Timing belt replacement for Toyota Corolla
Content
The timing belt is a very important part of the Toyota Corolla and plays an intermediate role between the timing mechanism and the pulley. While it is intact, there are no obvious manifestations of work on the toyota corolla, but as soon as it breaks down, subsequent operation becomes almost impossible. This will mean not only additional investment in repairs, but also a loss of time, as well as physical effort due to the absence of your vehicle.
On newer Toyota Corolla, a chain is used instead of a belt, so the procedure 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 on a Toyota Corolla is not difficult. If you are not confident in your abilities, it will be even more reliable to contact a Toyota Corolla service center or an ordinary service station, where professionals will carry out the replacement.
What is the timing belt cover for 1,6 and 1,8 liter engines:
- Cutout strap.
- Guide flange.
- Timing belt cover #1.
- guide pulley
- Heel.
- Timing belt cover #2.
- Timing belt cover #3.
Often, premature belt wear is due to the fact that too much tension was created and additional physical stress was created on the motor, as well as its bearings. However, with a weak tension, the gas distribution mechanism may collapse. To avoid such problems, it would be more convenient to regularly check and, if necessary, replace the belt drive, as well as professionally and promptly adjust its tension.
The procedure for dismantling the timing belt Toyota Corolla
First you need to disconnect the mass from the battery terminal, as well as the plus.
Block the rear pair of wheels and put the car on the parking brake.
We unscrew the nuts that hold the right front wheel, raise the car and put it on stands.
Remove the right front wheel and side plastic protection (to get to the crankshaft pulley).
Remove the windshield washer fluid reservoir.
We unscrew the spark plugs.
Remove the valve cover from the engine.
Remove the drive belts.
Remove the idler pulley from the A/C compressor drive belt.
If Toyota Corolla is equipped with cruise control, turn off the drive.
We install a wooden support under the car engine.
We put the piston of the first cylinder at TDC (top dead center) of the compression stroke, for this we reduce the mark on the crankshaft pulley with the mark "0" on the lower timing cover.
We pry off and remove the cover of the viewing window. We fix the flywheel and unscrew the bolt of the crankshaft pulley (should be removed without much effort).
Remove the timing belt covers, and then remove the timing belt guide flange.
Loosen the tension roller, push the roller and tighten the bolt again. We release the driven gear from the timing belt.
We unscrew a couple of nuts from the engine mount bracket at the bottom and one screw at the top.
Without completely removing the bracket, lower the engine and remove the timing belt.
We release the timing gear and it comes out of the engine compartment.
Precautions when replacing the timing belt:
- in no case should the strap be turned over;
- the belt must not get oil, gasoline or coolant;
- it is forbidden to hold the camshaft or crankshaft of the Toyota Corolla so that it does not rotate;
- The timing belt is recommended to be changed every 100 thousand kilometers.
Installing a timing belt on a Toyota Corolla
- We clean the engine well in front of the toothed belt section.
- Check if the crankshaft and camshaft marks match.
- 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 rest of the items in reverse order.
- We check the performance with the ignition on.
In no case should you start the toyota corolla engine until you make sure that the installation is done correctly.
