How to find timing belts marks toyota rav4 2l

How to find timing belts marks toyota rav4 2l



Can not find proper timing marks to set timing belt on toyota rav4 2 liter.



I have just replaced my water pump on my 1998 RAVE4, also, the timing belt and the other two belts. I had a tough time with the timing marks. The way you line these marks up is easy if you take the time, First, if you are changing the timing belt you pull the balancer and both top and bottom plastic covers,(do not try to pull top cover off before you take off balencer and the motor mount off or you will just break it.), Second after covers are removed you will have access to the timing belt, you can now remove it by loosening the tensioner bolt and pushing down on the tensioner wheel, the belt then can be taken off. Third take out number one sparkplug and replace the bottom cover by maybe two bolts so that you can see marks on cover, next replace the balancer and bolt. Turn the motor over by hand with the balancer so the small divit on the back of the balancer is on 0 or top dead center on the compression stroke, you can use a compression gauge for this or I just used a mirror and light to shine in the number one cylinder to see the piston. Next remove the balancer and cover and make sure to make a mark on crankshaft gear and housing. Next you will need mirror and flashlight, now turn camshaft gear clockwise to line the hole in the gear with the top timing mark. I recommend a small circle mirror for this. Now replace the belt. I turned the crank shaft gear one tooth counter clockwise off mark and the camshaft one tooth clock wise off mark so when the belt is on you can turn the camshaft gear counter clockwise to get tension on the belt and marks will line up. I would recommend changing water pump,tensioner wheel, and the idler wheel. After belt is on I would replace the bottom cover the balancer and the crankshaft sensor. Iwould then start it to make sure the water pump is not leaking and the motor is not pinging or you will have to tear it back apart again.

There is a hole in the cam gear that if you look through it with a mirror and light you should see a small notch in the cam cap. on the crank gear there is a small divot between the teeth just to the left of the keyway notch that should align with a small dimple on the oil pump cover.

How do I Time a Honda Accord?

Honda Accord Timing Setting



Properly timing a Honda Accord is one way to get the most out of your Honda Accord engine. An internal combustion engine's timing refers to its ignition timing. The ignition timing determines when a spark will occur to start the Accord's VTEC engine. The factory recommended setting for the Honda Accord VTEC engine varies from year to year but it generally falls between 12 to 18 degrees before top dead center. You can adjust the ignition time with a few tools and mechanical skills.

To Time The Honda accord You Will Need Few Basic Tools Like

timing light,timing adjustment setting,wrench and wheel chocks.

Follow The Steps Below:----

Park your car.Turn off all accessories in the car including the radio, air conditioning and heat.


Use wheel chocks to chock the wheels of your car. Put the transmission in neutral, firmly engage the emergency brake, and gradually take the engine to an idle speed of 750 rpm.


Exit the Honda Accord allowing the rpm to go back to zero and open the hood to your VTEC engine.


Connect the timing light to the battery by placing the red clip on the positive terminal first and the black clip on the negative terminal second. Next, connect the timing light clamp to the number 1 spark plug wire connected the the cylinder head. Then, shine the timing light on the pulley connected to the engine's crankshaft to see check the timing mark.


Check where the timing mark on the pulley falls compared to the degree tab on the front of the engine. You should now be able to see what the current ignition timing is. You can remove the installed components if the timing is correct.


Locate the distributor lock-down bolt at the base of the distributor housing and loosen it with your wrench. Disconnect the distributor vacuum hose from the distributor housing and you will not be able to adjust the ignition timing safely.

Rotate the distributor with your hand until the timing mark on the pulley aligns with the timing index you desire. Remember, 12-18 degrees is the factory recommendation.


Reconnect the distributor vacuum hose into the distributor housing and tighten the lock-down bolt with your wrench. Remove the timing from the battery, spark plug wire, and pulley. Close the hood of your car and remove the wheel chocks.


This Will Help.
