To be certain, I think you need to index the TDC on the end of the compression stroke, making sure it's not the exhaust stroke. I think cylinder 4 is TDC on the exhaust stroke at the same time as 1 is on the compression. It's easy to figure out which stroke when the spark plug is removed and you feel pressure on your finger. Timing notches should be visible on the block and with a large notch on the crank sprocket (with the cover off). A timing mark should also be visible under the car on the main pulley. I use chalk, or soapstone, to trace, or rub, the edge of the pulley. The mark reveals itself when it is filled with the chalk so you can see it easier. Wipe the pulley and it's right there. Beyond that, cam alignment should be done with an alignment tool for exactness.

If your plugs are on top, take the 1 cylinder plug out an insert a screwdriver inside of it. turn the cam until the screwdriver is to the last point of coming up. do this slowly because you don't want to be on the down stroke of tdc

Take a piece of wood ie tongue depresor, or long que tips. Remove the no. 1 plug, put the stick in the whole. Now you need to also have set up a breaker bar or a large socket rench to turn your crank. While turning the crank make sure that you are noticing where it goes up to and when it starts to fall. After studying where it goes up to and starts to fall. When the no 1 piston raises to the highest point. Then its at its top dead center. The reason I don't ever use any form of metal device is that it can score or damage the piston wall or the piston. Also make sure you don't use the setting as it is comming down, just when it is at its highest point.

Special note, when you change your timming belt on a 4 cylinder if you don't replace the water pump at the same time. You will be just a litle later.

Set timing on dodge ram

remove #1 spark plug, then have someone bump the starter while you hold your finger over the plug hole, Bring #1 cylinder up to T.D.C. (Top Dead Center) on firing stroke you will feel a rush of air push your finger off of the plug hole, check that the mark(or groove) that is cut into harmonic balancer,(what crank shaft pully is mounted to) is lined up with timming indicator on timming chain cover, check to see that rotor button is pointing at #1 on cap.
this should get you back to where you need to be if distributor was removed and engine was turned or moved.
then look at lable under hood if it is still there , if not check service manual for degree either before, or after T.D.C.
I hope this will answer your question

How do you set the timming on a 2.3 when your putting the new timming belt on

The IGNITION timing on your Ranger is computer-controlled and is not adjustable.

Should the camshaft drive belt/timing belt jump timing by a tooth or two, the engine could still run; but very poorly. To visually check for correct timing of the crankshaft, auxiliary shaft, and the camshaft follow this procedure:
There is an access plug provided in the cam drive belt cover so that the camshaft timing cam be checked without moving the drive belt cover.
  1. Remove the access plug.
  2. Turn the crankshaft until the timing marks on the crankshaft indicate TDC.
  3. Make sure that the timing mark on the camshaft drive sprocket is aligned with the pointer on the inner belt cover.

Never turn the crankshaft of any of the overhead cam engines in the opposite direction of normal rotation. Backward rotation of the crankshaft may cause the timing belt to slip and alter the timing.

See Figures 1, 2 and 3

Fig. Fig. 3: Releasing the timing belt tensioner using a special tool

  1. 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.

Always turn the engine in the normal direction of rotation. Backward rotation may cause the timing belt to jump time, due to the arrangement of the belt tensioner.
  1. Drain cooling system. Remove the upper radiator hose as necessary. Remove the fan blade and water pump pulley bolts.

Set timming inGOLF 1992

it sounds like the timing is out on the car, it needs to be exactly at TDC (top dead center) and do not move any of the fly wheels crankshaft wheels when timing chain/belt is off it may be that the timing chain is not tight enough
