Are you sure the belt tensioner spring is strong enough to keep the belt tight ?
You should have to move the tensioner to put the belt on, then it should keep the belt tight when you finish.

Change sepertine belt on engine.


it is not that fun, you need to have 1/4 inch tools, 10mm socket 8mm socket, 12 mm socket,18mm socket. and wrenches to match. you need to support car on jack stands and remove pass tire. Go to your local auto parts store and get a manual first. as the valve timing is very critical in the installation process !!!!!!!!!!! if this timing is not done exactly you will cause severe engine damage to valves and pistons. read manual and read again then assemble it right the first time as there is no room for error. Belt is 30 -50 $$$ depending where you go.

I have found the crankshaft marks but I cannot find marks to align the to over head cams on my car, the dohc are run from 1 wheel. I am trying to re-align the timing belt as i think they have gone off.


if it's a dual overhead cam then each head has two cams and two pully's, a single overhead cam engine has one cam and one pulley on each head. if the belt has more than 60,000 miles on it you should replace it. you need to find out if the engine is an interference engine or not to determine the level of damage caused if the belt has jumped or slipped. your overhead cam timing marks are usually on the cam faces and the backing plate behind the cam or sometimes there's two marks on the cam that you align with the surface of the head behind them. the first thing you need is a diagram of the belt routing and mark positions because timing marks are very important especially on an interference engine. starting or cranking an interference engine with the timing marks misaligned can bend all your valves or even punch holes in your pistons! so proper alignment is crucial, good luck.

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.

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.

I need to know the proper procedure for installing the dual overhead cam, where the timimg marks should be


If you look behind the cam gears you will see a little nipple or indention in the metal baking and in the cam gears there should be a little hole line the two of them up to have the cam gears lined up. On the crank gear you will have a little notch on the back edge of the gear and on the block you will see either a notch or a nipple on it at about 1 or 2 o'clock line them up. Put your belt on, sometimes you have to turn the crank counter clockwise one or two notches then put the belt on and turn it make clockwise to get all the slack out of the belt. This should get it right in time.
