Cam shaft How can you tell where the timing marks are without taking the cover off of the cam lower pulley marks

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.

Hi, the crankshaft marks are on the belt pulley and timing cover, so you have to mate it up to see them. The cam sprocket mark goes on the bottom, and aligns with another mark on the timing cover. There is a plug you pull out and hole to look thru to align the cam sprocket/shaft.








Rotate the engine so that No. 1 cylinder is at TDC on the compression stroke. Check that the timing marks are aligned on the camshaft and crankshaft pulleys. An access plug is provided in the cam belt cover so that the camshaft timing can be checked without removal of the cover or any other parts. Set the crankshaft to TDC by aligning the timing mark on the crank pulley with the TDC mark on the belt cover. Look through the access hole in the belt cover to make sure that the timing mark on the cam drive sprocket is lined up with the pointer on the inner belt cover.

All Mitsubishi cars pretty much hide the water pump under the timing belt. You should buy all new belts for the car and consider replacing the water pump at the same time.You will have to take off the power steering belt, the alternator belt, the upper belt cover, support the motor, take off the motor mount, jack up the right front corner of the car, take off the front right tire, take off the engine plastic under cover, line up the TDC timing mark, Take off the front wheel ,take off the plastic splash cover, using an air wrench take off the lower pulleys, take off the lower engine cover, observe the timing marks/arrows and highlight with paint (on the crankshaft,counter balancer shaft , and cam shaft),take off the timing belt, counter balancer belt if there is one, water pump belt, and now you can unbolt the water pump, scrape the gasket, and replace it. Now the good news, if you have tools,a compressor, an air gun(for lower pulley bolt), patience , and four to eight hours to kill, you can actually do it your self.

rule of thumb on most applications the keyway on the cam and crankshaft is at the 12o'clock position for top dead center

He said it's a 2.0 Liter. 1990 and 91 are the same. the crank shaft pulley lines up with the "0" mark located on the lower portion of the timing belt/water pump/oil pump cover. the top cam pulley lines up with the hole and a small dimple in the engine block behind the pulley, it;s super irritating to find and see, to be sure it;s correct you can put a small dill bit backwards into that hole and look careful with a flash light, sucks but it works. why am i here? i wanted to know what the crank shaft is positioned at when the cover is not on so i don't have to install the pulley to find it again. I have accidentally moved everything when I was installing the belt after the water pump and all the other stuff. i think they should have put the marks on the block as well as the plastic cover.it's a pretty important thing after all.

when the thing you are reading says somethings at 11 o clock, it means it;s at 11 o clock. Not 11 O clock after and earth quake tilts your house. the dimple in the engine lines the cam shaft pulley up with the hole in that pulley at 11 o clock. 12 being straight up 11 being behind that towards the windshield/passenger seat.

when you are installing that timing belt make sure your slack that is going to get grabbed up when un blot the spring tensioner is coming from below. if there is slack between the water pump and cam shaft pulley it will still be there when you release the tensioner.

put it on tdc
and go from there
tdc top dead center

You did it the right way. If you tried to make a full cam revolution you would have hit the pistons with the valves. Put the lower timing cover and crank pulley back on. If the cam marks are aligned right and the mark on the lower timing cover lines up with the mark on the crank pulley, you're good to go.

1. remove air intake pipe, and box (upper and lower section)
2. take off timing belt cover
3. take off serpintine belt, and v belt
4. rotate engine to TDC marks line up on crank and cam. camshaft says O^T on it and on the cover behind gear, crank has a notch in the pulley and a arrow on the cover to line up
5. remove crank pulley 6mm allens not the 19mm 12 bolt
6. make sure timing belt is still at TDC remove lower timing belt cover there is 3 bolts and a nut holding it on the nut is by the water pump and the bolts are on on top and 2 behind the crank pulley
7. remove cover
8. mark intermediate shaft shaft right above the crank pulley
9. remove belt
10. install reverse of removal make sure to line up all 3 pulleys cam crank and intermediate shaft or it wont run and depending on how bad it is out of time if you do it wrong you could bend valves

Assuming this is a 2.0 8v your question is pretty vague

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.

the crank has the only mark you have a procedure for the cam gear you should see if the local dealer will print this out for you
