SOURCE: how to find timing belts marks toyota rav4 2l
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. Good luck and no I am not a certified mechanic just thought this would be helpful from my own experience.

On the crankshaft gear there is a VERY small dimple that aligns with a mark on the motor. The mark on the motor (a small triangle) is at roughly 11 o'clock. After you line these timing marks up look at the camshaft gear and you will see that on one of the spokes there is a hole. You need to use a mirror to line this hole up with the dimple on the cover that is behind the camshaft gear. (It is at roughly 1 o'clock) If this hole is 180 degrees from where it should be you need to rotate the motor 1 more revolution at the crankshaft and it should now be lined up, or close. Once lined up I like to take a silver (metallic) Sharpie and make my own mark on the camshaft gear and on the backing plate that is behind it. You can make this mark where ever it is convenient for you. As long as you know where your marks line up, that is all that matters. This way I don't have to use the mirror as often.

On the 4A-FE engine do the following:
Align the camshaft knock pin with the knock pin groove on the pulley side with the K mark, the slide on the timing pulley.
Align the camshaft knock pin with the knock pin groove of the pulley, and slide on the pulley.
Align the camshaft knock pin with the groove on the pulley side with the K mark-4A-FE engine
Temporarily install the timing pulley bolt. Hold the hexagonal wrench head portion of the camshaft with a wrench, and then tighten the timing pulley bolt to 43 ft. lbs. (59 Nm).
Install the crankshaft pulley. Align the pulley set key with the groove of the pulley. Slide on the timing pulley, facing the flange side inwards.
