Take off the intake side, then set the #1 cylinder to top dead center. When you install the cams, set them close to where the marks should be. Alignment is critical when you put the belt on. After the belt is on turn the engine two revolutions by hand and recheck/reset your marks. Every time you reset it, turn the engine again and recheck marks.

Instruction changing timing belt 1979 Alfa Romeo Spider Veloz?

With Cam Caps loosened, FIRST loosen timing chain tensioner, press it in to loosen tension, Crank using ratchet to TDC (Top Dead Center on crank pully, (to keep from damage to pistons), align Exhaust Cam Timing Mark to mark on #1 Exhaust cam cover, then take up slack between Exhaust & Intake Cams (on top between the cams), Then align the Intake Cam to mark on #1 Cam Cap, "Now" loosen the 17mm bolt to tighten timing chain, rotate engine using rachet two times, reset TDC at the crank, and look at "Cam Timing Marks on both the Exhaust, and Intake Cams. If you did all this correctly the "Timing Marks" should be lined up so TDC,Exhaust, and Intake marks are all the same.

When setting timing after broken timing belt, how do you know when # 1 is at TDC with both intake and exhaust valves closed? What is TDC?

TDC is an acronym for Top Dead Center. It is when the piston has reached the very top of its travel and there is nowhere for the piston to go but down. If you align the timing marks on the engine, the piston will be at TDC with the valves on #1 closed.

To position your crankshaft and cam to the correct position, it should be done BEFORE removing the belt if possible. If the belt has already been removed and/or the belt was broken, the same principles apply, but you will have to go about it completely different.

Turn the engine clockwise to align the "O" on the crankshaft pulley with the "O" on the outer timing belt cover.
Remove the plug in the outer timing belt cover and look through the hole. The timing marks on the camshaft pulley should align with the cover pointer. If they do not align, rotate the crankshaft one full revolution and align the "Os" again. They should now align. When every thing is lined up like this, your engine is timed to #1 at TDC and the valves on #1 cylinder will be closed.

Now if the belt has already been removed or if the belt was broken, You may have to temporarily put the outer cover back on. You may have to put it on and take it off several times until you get things lined up. Time the crankshaft "Os" first. It will not matter which rotation you are on if the belt is not installed. (TDC is TDC - the piston doesn't really care where the valves are - that's the camshaft's problem LOL)
After the crank shaft is lined up, turn the camshaft so the timing marks line up with the pointer. Then remove the front cover and install your belt.

After setting the timing belt tensioner, rotate the engine two full turns clockwise and recheck to make sure that all the timing marks still line up. If they do not - repeat the procedure.

Where is tdc on my 2001 dodge ram 1500

top dead center
ok look at your damper pulley its the pulley at the bottom of the motor
the damper pulley has a line cut in it
line the mark up with the degree marks
you want to put it on the zero mark
once you have done this you are on top dead center
also number one cylinder must be on a compression stroke
pull spark plug number one turn the motor over with your finger
over the hole when you feel compression that's when you line
up the marks.

hope this helps you
good luck

Okay. I'm fixing my 1994 Saturn SL2 timing chain and I did everything the directions told me, but the timing marks aren't lining up correctly. I don't know what to do. Please help me.

It is not rare for people to have problems with engine after replacing the timing belt. In all my cars I do it by myself. It is not impossible, but you will spend more time than a professional. If you decide to do it by yourself, then get the Haynes Repair Manual (Based on a complete tear down and rebuilt), specific for your car. I have one for each of my cars. Go to the part Engine, and use the chapter Timing belt removal inspection, and Top Dead Center (TDC) location, and put the number one piston at TDC on the compression stroke. This can be found by putting the thumb over the spark plug hole and the pressure will push your finger upward till piston reaches the upper point. You have the crank shaft with a wrench. Now you are in compression stroke. To locate Top Dead Center Location, this can be done by inserting a long blunt object into the spark plug hole. Note the point where the object stops moving out this is the TDC.
Are you sure that the piston at cylinder N#1 is at TDC on compression stroke. Please check it out, and if not correct.The timing marks can be lining up correctly, ONLY if the piston at cylinder N31 is at TDC in compression stroke. I repeat again in compression stroke.

I need to know how to set my cam in time so my car will start

to begin with timing a camshaft, the motor needs to be set at top dead center of the compression stroke. If you are unsure what this means, remove the valve cover on the driver side, rotate the crank pulley with a 32 mm socket, until you see the intake valve, which is the second valve spring, begin to compress. When I say compress, this means the valve spring is opening the valve. As the valve spring begins to close, the piston will be approaching the top of its travel. The crank shaft pulley/harmonic balancer, will have a mark to indicate top dead center on the timing cover. This Mark will align with the TDC mark on the timing cover just after the intake valve spring closes. Next, using a half inch wrench, remove the distributor and set to the side. With a flashlight, look down inside at the oil pump driveshaft. It will have a slot in the center of the gear. This slot should be pointing towards the number one intake manifold bolt hole. It will almost be front to back.

If it is not, using a long flat blade screwdriver, rotate the oil pump driveshaft clockwise until the slot lines up with the number one intake manifold bolt hole. Reinstall the distributor and snug the half inch bolt down. The rotor should be pointing towards the number one cylinder mark on the distributor plate. Reinstall the distributor cap and try to fire the motor over.

How to set timing mark

Timing mark is appearing with number 0 and line marks on the area near the pulley crankshaft.
The crankshaft pulley mark has to be lined up with the cam shaft mark and the piston # 1 has to be on top position providing its intake and exhaust valves in close position. This is called TDC ( top dead center). It sounds complicated to understand, but it is simple to imagine like this: All valves are closed and Piston #1 is up at high position to make a peak compression and a spark ignites to make a compression pushing the piston down to make a stroke. Hope this can help.
