You are changing the timing belt and you need o know where the timing marks are for the cam shaft and the crankshaft on a 1994 corolla Also how do you align the marks to put engine in time?

If you removed the tensioner and didn't lock the cams and crank down then you have to re-time the engine. It sounds like you let the exhaust and intake cams move.

Remove the spark plugs, put a ratchet on the crank pulley, slowly rotate engine until the cams line up. Once the cams are lined up remove, the timing belt and bring the crank around to the timing mark. put belt back on and let the tensioner go. put plugs back in...see if it'll start.

1996-1999 Toyota Corolla valve timing:
It is very easy to install the timing belt on 1997 Toyota Corolla. Do the following:
- Mark the numbers 1,2 and 3 on the spark plug wires with permanent marker or nail polish and remain the 4th one unmarked. This is necessary so that you can easily remember the spark plug wires order later on their original position.
- Remove the spark plugs so that the engine can easily be rotated.
- Rotate the crankshaft clockwise to align the v- groove mark on the crankshaft pulley with the 0 mark on the timing belt cover. If these marks are aligned the piston is always on the Top Dead Position (TDC).


- To replace the timing belt remove the crankshaft pulley, upper and lower timing covers.
- Temporarily screw in the crankshaft bolt in its place to rotate the crankshaft with the spanner and align the v- groove of lower crankshaft gear with the index mark on the oil pump cover as shown in the following diagram.
- Inspect the cam shaft mark through the small hole on the cam shaft sprocket. The punch mark should be exactly behind the hole on the cam shaft sprocket as shown in the following diagram.



- Loosen the timing bearing bolt, press the bearing forcefully against the spring with some suitable tool and lock it there temporarily.
- Remove the timing belt.
- Remove the timing bearing.
- Replace the new timing belt and bearing with the original.
- Install in the reverse order of dis-assembly.
NOTE: NEVER PUT EXTRA FORCE ON TIMING BEARING TO ADJUST THE TIMING BELT TENSION. JUST LOOSEN THE TIMING BEARING BOLT AND THE SPRING ATTACHED TO IT WILL PULL THE BEARING IT SELF WITH THE PRESET TENSION TO ADJUST THE TIMING BELT.
Thank you for visiting Fixya.

Line up the cam shaft pulley mark with the mark on the head. Bring the crankshaft pulley timing mark to 0 and put the belt on.

2.3 Liter distributorless engines the timing belt keeps the cam in time with crankshaft and the auxiliary shaft runs the oil pump line up marks to corresponding marks install belt. but there is a inspection hole on front of cover rotate crankshaft line up on tdc remove plug a dimple in gear should line up pointer if not rotate crankshaft 360 degrees check again no dimple belt has jumped from loose tensioner.

the marks are on the gears of the cams and crank shaft easy to see might have to cleah it off some line marks up in between dots and install tenson hope this helps.

Why remove the gears? No need to. Just be sure they are clean of any belt residue. The gears are locked in the correct position for the shafts.
You need to rotate the gears to position the shafts (Crank and Cam) to the correct position before installing the belt. Follow the instructions that should have come with the belt. Usually need to line up some marks on the gears to marks on the engine case for the valve timing to work right.
Pull the spark plugs so you can turn the crankshaft easier (BY HAND ONLY) Mark the wires to reinstall correctly. I did this a long time ago. Seem to remember pointing the mark on one gear to the mark on the other gear. Use a straight edge to line up the two. Dont take this as gospel.
Good luck.

Here is the trick. Align marks. Put the timing belt on the crank shaft pulley first, and after on the overhead cam pulley. Release tensioner and rotate the crank shaft till the timing belt makes two full circles. Try to align marks, you will be at least one tooth off. Align the crank shaft on the mark, and find out how many teeth you are off at the cam shaft pulley. Count the teeth. Remove the timing belt from cam shaft pulley only. Move cam shaft pulley in reverse according to the number of teeth you counted. Make sure the crank shaft pulley is on the mark. Mount the belt at cam shaft pulley.Rotate the belt two circles and check the marks. Repeate this procedure til after releasing the tensioner, and rotating the timing belt two full circles, the mars will be align.

My sincere apologies for the severly delayed response.
I am personally going back to answer your unanswered questions.

I do not know if you still need this information, however I am answering it in case you still do.


Click on the following direct Link. It has the Timing Belt Diagrams with Marks for the Camshaft and Crankshaft that you will need.

Again my apologies...
Let me know if this helped, or if you have additional information or questions. Feel Free to contact me at FixYa.com

The timing marks are on the car. Line up the dot on the cam pulleys with the line on the head. The Crank-shaft sprocket has a groove and the block has a dot to line up with. Make sure the crank-shaft is at TDC on the compression stroke, not the exhaust stroke. You can do this by removing the spark plug at the #1 piston, and inserting a wood dowel to feel for the top of the piston. It needs to be at the top, not the bottom.
No belt slack betwwen the cam pulleys...all slack should be at tensioner. Check the tension of the timing belt at a top point halfway between the two camshaft sprockets. The correct deflection is 4mm at 4.4 lbs. pressure (2 kg). If the tension is correct, tighten the idler pulley bolt to 27 ft. lbs. (37 Nm).
Let me know if you need any other tips.
Good luck!

I hope you've solved the problem by now, but there are alignment marks on the crank shaft (top pulley), idler (lower side), and cam shaft (smaller, bottom pulley) which should be aligned with stationary marks on the timing belt rear cover.

The belt has marks that align with the aforementioned marks (lines). The double marks on the belt align with the camshaft marks and the single marks with the others.

Loosen the tensioner clamp (nut) to allow the spring loaded tensioner to press on the belt and retighten the nut.

Rotate the crank shaft (clockwise, probably two revolutions) and make sure the pulley marks realign to the marks on the cover (they don't have to realign with the marks on the belt).

Rotate the crank shaft a full revolution once the belt is on and check that alignment is preserved.

Periodically loosen and retension the tensioner nut (access through a hole in the cover) to ensure that tension is maintained as the belt relaxes.
