Replacing the Toyota Corolla timing belt, how to change the chain in the engine?

Repairing and replacing a Toyota Corolla timing belt or replacing a chain in a Toyota Corolla engine is a rather labor-intensive process and requires the skills of a real car mechanic. The only consolation is that the timing chain on the Toyota Corolla requires virtually no maintenance.

But if the mileage on the car is quite high, and the noise under the hood increases, then this operation cannot be avoided.

But if you still decide to carry out the repair yourself, then carefully read the following instructions. Without this, it will not be possible to replace the chain, since the operation is quite complex, painstaking and very long.

The ideal option is to carry out such a replacement on a removed motor.

https://www.youtube.com/watch?v=aiz6HlP2fhs

The timing chain components are shown in the schematic diagram just below.

To get to the Toyota Corolla timing belt, you will need to perform the following operations:

1. Remove the right engine mount cushion 2. Remove the ignition coils 3. Remove the cylinder head cover 4. Remove the poly V-belt tensioner assembly

5. Remove the right engine mount bracket

An important point is to install the piston of the first cylinder at TDC of the compression stroke, for which you need to perform the following operations -
Rotate the crankshaft pulley and align the mark on it with the synchronizing mark “0” on the timing chain drive cover. Make sure that the marks (dots) on the camshaft drive gears are located opposite each other, as shown in the following diagram.

Otherwise, rotate the crankshaft 1 revolution (360°) and align the marks as indicated above.

Next, we remove the crankshaft pulley, for which official dealers use a special tool SST 09960-10010 (09962-01000, 09963-01000).

Another important point is removing the chain tensioner, for which you need to unscrew two nuts, see the photo below.

NOTE
Do not rotate the crankshaft if the chain is not tensioned by the tensioner.

Removing the Toyota Corolla timing chain drive cover. Remove 10 bolts and 2 nuts. Using a TORX E8 socket wrench, remove the stud. Separate the timing cover by inserting a screwdriver between the cover, the cylinder head and the cylinder block, looking at the location of the bolts on the cover.

The timing chain drive cover seal must be changed when replacing the chain.
Next, remove the chain tensioner shoe by unscrewing just one bolt.

To remove the Toyota Corolla timing chain, use 2 screwdrivers to remove the chain along with the drive gear, as shown in the figure below.

Be sure to place a rag under the screwdriver to avoid damaging the engine. If it is necessary to turn the camshafts with the chain removed from the gears, the crankshaft should be turned no more than 1/4 turn to avoid contact of the valves with the pistons.

Installing a new timing chain.

Set the piston of the first cylinder to TDC on the compression stroke. To do this, align the marks on the timing gears. Turn the camshafts by the hexagonal part so that the 2 marks (dots) on the drive gears are located opposite each other.

Turn the crankshaft by the crankshaft pulley bolt until the timing gear key aligns with the dot mark on the oil pump, as in the following diagram.

Install the chain tensioner shoe and secure it with the bolt. Tightening torque: 18.5 Nm. Install the crankshaft angle sensor sprocket with the “F” mark toward the front of the vehicle.

Installing the Toyota Corolla timing chain drive cover is a very important operation that requires care and precision.
Remove any remaining old sealant from the mating surface of the cylinder block and drive cover.

Apply the sealant in a continuous bead (diameter 3.5–4.5 mm) as shown in the following illustration. Scheme for laying sealant on the timing cover side.

Secure the timing chain cover with 10 bolts and 2 nuts.
Tightening torque: 13 Nm for bolt A and nut A. 18.5 Nm for bolt B. Using a TORX E8 socket wrench, tighten the stud. Tightening torque: 9.5 Nm.

Installing the chain tensioner assembly.

Make sure there is no dirt on the O-ring, then install the hook as shown in the figure below.
Apply a thin layer of engine oil to the O-ring. Secure the chain tensioner with 2 nuts. Tightening torque: 9.0 Nm. If the hook comes loose when installing the chain tensioner and releases the plunger, re-lock the plunger with the hook.

Next, install the crankshaft pulley and tighten it to 138 Nm. The position of the crankshaft when removing the plunger should be as shown below.

Turn the crankshaft counterclockwise, then remove the hook from the locking pin and release the plunger.

Checking the operation of the plunger will ensure that the chain tensioner is working properly. Turn the crankshaft clockwise and make sure that the plunger presses the chain tensioner shoe. If the plunger does not extend, use a screwdriver to push the shoe toward the tensioner until the hook disengages from the locking pin so that the plunger can extend.

Apply a thin layer of engine oil to the crankshaft position sensor O-ring.
Secure the crankshaft position sensor with 2 bolts. The tightening torque of these bolts is 9.0 Nm. Install the coolant pump assembly. Install the right engine mount bracket with a tightening torque of 47 Nm. Install the serpentine belt tensioner assembly.

Secure the cylinder head cover and 3 mounting brackets with 9 bolts, 2 sealing washers and 2 nuts. Bolt tightening torque: 11 Nm for bolt A and nut A, 9.0 Nm for bolt B.

The long-term and reliable operation of the Corolla engine depends on the correct assembly of the timing belt, so install and assemble the chain carefully. Don’t forget to apply sealant to all the places where you removed it during disassembly, in order to avoid oil leaks in the future.

How does a Toyota timing belt change?

The timing belt is one of the most important engine components. The service life of the power unit depends on the timeliness of its replacement. If you have special skills and tools, and, most importantly, if you strictly follow the sequence, replacing the Toyota Corolla timing belt is a simple operation. You can do it yourself in a garage.

The timing belt in your engine is the most important maintenance item for your vehicle. What happens if this component breaks? How often does the belt need to be changed? Is it difficult to replace the timing belt yourself? You will get answers to these and other questions in our material today.

Japanese cars are very reliable and high quality, however, they do not last forever. This primarily applies to such a car brand as Toyota.

Like any other car, the service life of many components depends on the conditions and time of operation of the car. First of all, it affects filters, all kinds of rubber bands, chassis, and also the timing belt.

In this article we will talk about how to correctly replace and adjust the timing belt according to the marks on a Toyota Corolla.

Many car owners ignore the need to replace the timing belt due to the high cost of this procedure. Unfortunately, this oversight can lead to more serious damage to the engine and its components, which will cost much more to repair than just replacing the belt. And if the belt, for example, breaks, the engine will simply stall and stop functioning.

The timing belt performs a very important function in the design of a car, since it is an intermediary between the gas distribution mechanism and the pulley (its drive). The quality of the engine itself and its power characteristics depend on the operation of the timing belt. The consequences of a belt failure are immediately noticeable to the driver, as driving the car becomes almost impossible.

More details: grandrepairauto.ru

I got around to the timing belt and bought it in the fall. Either there is no tool, or there is no place, but then I discovered My Own Mechanic and went to change it. You can find the numbers of the belt and rollers in my last blog post. Climbed from below, unscrewed the power steering belt tensioner (red mark) and loosened the lower bolt of the power steering pump (yellow mark)

To replace the timing belt you will need the following tools: - Socket heads for 10, 12, 14, 19 and an extension for them - A driver and a ratchet - A set of open-end wrenches - Clamps or a strong thin thread. — Powerful clamps — Hammer 300-400g.

— Claw puller with a jaw span of at least 100 mm. for oil seals - Clamps for tightening the timing belt - Marker for marks - It is advisable to prepare a device for fixing the pulley. You can make do with improvised means, but this is quite inconvenient and you need a large selection of improvised means.

— It is advisable to use a torque wrench.

https://www.youtube.com/watch?v=K7XcLe-3sAc

Making room for access to the belt First of all, you need to disconnect the resonator, the cooling system hose and the air cleaner. Afterwards the spark plugs are disconnected, but you don’t have to do this.

Don’t forget to disconnect the battery, and you also need to remove the radiator fan and all V-belts, and the belt cover also needs to be removed.

To remove the belt, you need to remove it in the place where the triangles are, the force should be directed according to the arrows.

repair, information for maintenance, automotive news, reviews, diagnostics, forum Replacing the timing belt (timing belt), oil seals, tension pulley of the engine of a Toyota model 4a-fe.

Toyota equips cars with a particularly common and reliable type of engine, the 4a-fe model. It features a sixteen valve timing system, eight intake and eight exhaust valves, and two camshafts. Cylinder displacement 1.

6 liters, developing a power of 115 horsepower, delivering maximum comfortable, maneuverable driving.

The timing belt is responsible for the quality operation of the engine, and it is with its help that the gas distribution mechanism of the internal combustion engine is driven.

The mechanism, in turn, promotes the correct supply of the fuel mixture to the cylinders, then removes combustion products. When the engine is running, the timing belt is in constant motion, performing a transfer function.

Replacing the timing belt on a Toyota Corolla is an important routine procedure.

Toyota Corolla timing belt replacement

The timing belt is a very important part of the Toyota Corolla and it plays an intermediary role between the gas distribution mechanism and the pulley.

While it is intact, there are no obvious signs of work in the Toyota Corolla, but once it breaks, further operation will become almost impossible.

This will entail not only additional capital investments in repairs, but also loss of time, as well as physical stress due to the absence of your own vehicle.

On newer Toyota Corolla cars, a chain is used instead of a belt, so the order of work will be different. In this article, the replacement is made on the 4A-FE engine, but the same will be done on the 4E-FE, 2E and 7A-F.

Technically, replacing a belt drive in a Toyota Corolla is not difficult. If you are not confident in your abilities, it would be safer to contact a Toyota Corolla service center or a regular service station, where the replacement will be carried out by professionals.

What does the timing belt cover of 1.6 and 1.8 liter engines consist of:

Toothed strap.
Guide flange.
Toothed belt cover No. 1.
Drive pulley.
Stub.
Toothed belt cover No. 2.
Toothed belt cover No. 3.

Often, premature wear of the strap is due to the fact that too much tension was created and unnecessary physical stress was created on the engine, as well as its bearings.

However, if the tension is weak, the gas distribution mechanism may be destroyed.

To avoid such problems, it would be more advisable to regularly check and, if necessary, replace the belt drive, and also professionally and efficiently adjust its tension.

Procedure for removing the Toyota Corolla timing belt

First you need to disconnect the ground from the battery terminal, as well as the plus.
Block the rear pair of wheels and set the car to the handbrake.
We unscrew the nuts securing the front right wheel, lift the car and place it on stands.
Remove the front right wheel and the side plastic protection (to get to the crankshaft pulley).
Remove the washer fluid reservoir.
We turn out the spark plugs.
Remove the engine valve cover.
Remove the drive straps.
Remove the intermediate roller of the air conditioning compressor drive belt.
If the Toyota Corolla is equipped with cruise control, unscrew the actuator.
We install a wooden stand under the car engine.
We set the piston of the first cylinder to TDC (top dead center) of the compression stroke; to do this, align the mark on the crankshaft pulley with the “0” mark on the lower timing cover.
We pry up and take out the cover of the inspection window. We fix the flywheel and unscrew the bolt on the crankshaft pulley (it should come off without much effort).
Remove the timing belt timing belt covers, and then remove the timing belt guide flange.
Loosen the tensioner roller, press the roller in and tighten the bolt again. We release the driven gear from the timing belt.
We unscrew a couple of nuts on the engine mount support at the bottom and a bolt at the top.
Without completely removing the support, lower the engine and pull out the timing belt.
We free the drive gear from the timing belt and it is removed from the engine compartment.

Precautions when replacing the timing belt:

Under no circumstances should you turn the strap inside out;
The strap should not come into contact with oil, gasoline or coolant;
It is prohibited to hold the camshaft or crankshaft of a Toyota Corolla from turning;
It is recommended to replace the timing belt every 100 thousand km.

Installing a timing belt on a Toyota Corolla

We thoroughly clean the front part of the engine in the area of the toothed belt.
We check whether the crankshaft and camshaft marks are aligned.
We put the belt drive on the driven and driving gears.
We put the guide flange on the crankshaft.
Install the bottom cover and crankshaft pulley.
Install the remaining elements in the reverse order.
We check the functionality with the ignition on.

Replacing the timing belt on 4e-fe - logbook of the 1994 Toyota Corolla Lastochka on DRIVE2

Here is my mini photo report.

I put chocks under the rear wheels , jacked up the car, and removed the left wheel

Opened the hood, loosened the power steering pump bolt

Climbed from below, unscrewed the power steering belt tensioner (red mark) and loosened the lower bolt of the power steering pump (yellow mark)

Next, I loosened the generator tension bolt.

Unscrew the four bolts of the timing belt cover

I took out the power steering and alternator belts. Pulled out the top of the protective cover

We move under the wheel arch and unscrew one of the pulleys. We hold the central bolt (at 19), and unscrew the small ones (I think at 12)

In theory, the pulley should be removed without effort, but I had to sweat to remove it. Just in case for beginners: crankshaft - from below, camshaft - from above =)

Next, use a crank to turn the central bolt of the pulley clockwise until the mark on the camshaft aligns. And the slot on the pulley should meet the zero on the plastic protective timing cover . My timing belt was at -10, when I removed the timing belt, I turned the crankshaft by about one tooth.

Now you need to clamp the pulley so that it does not turn and unscrew the central nut. It got really stuck on me, it didn’t want to wrench, after a lot of watering with WD40 and a pneumatic gun, it came unscrewed.

Next, I removed the remaining pulley with a puller, although in theory it should also come out without effort.
Unscrew the 3 remaining bolts of the protective timing cover and pull it out. I miraculously didn’t have a photo, but you can see them, I think you’ll figure it out. After you remove the cover, there will be something like a perforated washer . She just pulls it out by hand.

We removed the cover and see this picture. It is necessary to loosen the tension roller bolt and remove the spring.

Next, unscrew the parasitic roller bolt and remove the timing belt.

Next we install a new parasitic roller

Then put the new timing belt on from below, pull it into tension through the parasitic roller and put it on the camshaft. Make sure it doesn't sag or jump off the tooth.

Next, install the tension roller and put the spring in place

Tighten the idler and tension pulley bolts.

Next we assemble in reverse order. Reinstall the perforated washer , the toothed belt protective cover, then the pulley on the crankshaft and tighten the bolt.

Check the labels again

Just in case: the marks on the crankshaft (zero on the toothed belt protective cover) and the camshaft (point 4E with the top point) must align.
There is also an intermediate shaft, to the right of the crankshaft. The intermediate shaft does not have any clear position that needs to be “set”. Its rotation only causes the gears in the oil pump to rotate.

Now use the crank to turn the crankshaft pulley a couple of turns clockwise, thereby checking that you have assembled it correctly.

If everything is OK, then we assemble the rest: the second pulley, the upper part of the toothed belt protective cover.

We tighten the power steering belt with a bolt, and we need to rest the generator against the crowbar so that the poly V-belt is tensioned and tighten the nut.
Well, now you can start the engine and enjoy life.

Renting a box with a tool for 2.5 hours cost me 500 rubles, instead of 3-4 thousand for a replacement at the service. I'm happy)

Toyota Corolla timing belt replacement

The timing belt performs a very important function in the design of a car, since it is an intermediary between the gas distribution mechanism and the pulley (its drive).

The quality of the engine itself and its power characteristics depend on the operation of the timing belt.

The consequences of a belt failure are immediately noticeable to the driver, as driving the car becomes almost impossible.

If you drive a car without eliminating this problem, you can break down many other parts located in the gas distribution mechanism, which will entail large material costs. But in addition to the integrity of the timing belt, setting the belt tension plays an important role in its performance.

The belt should not be too tight, otherwise this will lead to its failure, as well as to additional mechanical loads on the engine and bearings.

But also, the belt should not be loosely tensioned, as this will lead to improper operation of the gas distribution mechanism, which will lead to its destruction.

To solve a problem with the timing belt you need to:

Replacing the timing belt with a new model of appropriate quality.
Adjustment of belt tension according to all rules.
Maintenance of the timing belt during machine operation.

The process of replacing the timing belt in a Toyota Corolla is not a complicated procedure, which is why it is easier to do it yourself than to take your car to a car service center, where you will spend a lot of money and time.

Precautionary measures

What to watch out for when replacing a timing belt:

Don't forget to remove the battery terminal.
Do not turn the crankshaft and camshaft on the timing belt, as this can lead to valve failure.
Also, do not forget to unscrew the spark plugs, otherwise you may get injured when turning the crankshaft with a wrench.
If the tension pulley bolt is loose, the engine should never be started, as the timing belt and cover may be damaged.
It is not recommended to use the starter when unscrewing the pulley bolt.
The belt must not be stretched, bent or twisted.
Also, do not stretch high-voltage wires.
The plastic cover is very easy to damage, so when you fix the pulley, do not lock it by the surface that is located under it.
Do not use a hammer to hit the edges of the pulley as they are very fragile.

Replacing the timing belt

To replace the timing belt on a Corolla you need:

First you need to remove the battery terminal, explosive wires and unscrew the spark plugs.
Remove the cover that covers the window in the engine shield and loosen the generator belt, then remove it.
Now you need to fix the pulley and loosen the fastening bolt.
The next step is to unscrew the nuts securing the cover, lifting it up.
Now unscrew the other valve cover mounting nuts.
Unscrew the fastening bolts in the upper timing belt cover.
Now carefully inspect the belt, if it is tight, without cracks or damage, this may mean that it is a new model or is still in good working order.
The hole on the camshaft pulley should be 5 mm and marked 2E; if this is not the case, turn the crankshaft and check the marks.
Now you need to unscrew the pulley mounting bolt, after which you need to spray this place.
Slightly rock the pulley in different directions and try to remove it. If it doesn't work, use a wooden block for this.
After this, you can unscrew the bolts securing the timing cover and remove it, then remove the guide washer.
Now temporarily secure the pulley in place and turn the crankshaft clockwise, now remove the pulley.
After you loosen the tension roller, you need to push it all the way to the left and then tighten it.
Finally you can remove the timing belt. Loosen the bolt, remove the spring, and then remove the tension roller itself.
Next, you need to clean the space under the timing cover from dirt, dust, and so on.
The next step is to install a new idler and tension roller and a second spring.
To tighten the tension roller bolt, it must be pressed down until it stops.
Check that everything is in place and has not moved, and now you can put on the new timing belt from bottom to top.
Now install and secure the belt washer and its lower cover.
Rotate the crankshaft in a clockwise direction until all marks line up.
Check the belt tension; if the tension is correct, it can be twisted 90 degrees.
Now you need to tighten the pulley bolt, install the upper timing cover and tighten the bolt.
Next, you need to install and tension the alternator belt, and then install the spark plugs.
The work has almost come to an end; we need to reinstall the valve cover and engine boot cover.
Now we connect the battery terminal, making sure to tighten it with a bolt.
Finally, start the engine and check for normal operation; there should be no extraneous sounds.
