SOURCE: serpentine belt slips off idler pulley

The A/C pully is supposed to spin freely until the AC is activated to run.. The cranshaft pully does not. Replace the tensioner pully. The belt has to fit in between the grooves on the pullys.

SOURCE: can't remove crankshaft timing belt pulley BOLT!

You will have to brace the crankshaft somehow, either by way of the flywheel, or the pulley. The trick to getting the bolt to break is "heat". Propane will sometimes work, but it's generally not hot enough. You want to get that bolt glowing if you can, and hit it with air impact then. Be careful not to burn yourself!

I hope this helps you, and I wish you luck on your repair.

Serpentine belt 1999 chevy malibu is slipping off cranshaft pulley


Make sure that the belt is fully seated in ALL pulleys, if it still slips off, then you have a pully that is bent, or out of alignment.

2003 impala was making squealing noise from serpentine pulley area, finally belt slipped off. Changed both Tensioner and belt, same problem as before, belt slipped off again, pulleys seem to turn alright,...


Remove the belt, and check each pulley for resistance, or play. Each pulley should turn with ease, and have little to no play. Replace any pulleys that are found to be faulty. Check for pulley alignment. If the Crankshaft Pulley or any other pulley has loosened up, or not aligned properly, the belt will come right off. This is usually due to a frozen or faulty Idler Pulley or Tensioner Pulley. If all else checks out, ensure that the ribs are properly installed on each pulley, and no ribs are hanging off of any pulleys.

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.
REMOVAL & INSTALLATION

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.

  1. Step 1 Find the belt tensioner pulley. The tensioner pulley is generally between the crankshaft and a component toward the top of the hood area.
  2. Step 2 Check the belt routing so you know how to replace the belt. You may be able to find a belt routing diagram on a decal on the fan shroud or in support documentation. Otherwise, make you own sketch for reference.
  3. Step 3 Rotate the belt tensioner pulley, using the wrench, to and relieve tension on the belt.
  4. Step 4 Slip off the old belt and slowly release the tensioner pulley.
  5. Step 5 Use your belt routing diagram to put the new belt onto all of the pulleys. Pay close attention to the water pump pulley, as incorrect routing can cause the water pump to run backwards and overheat.
  6. Step 6 Make sure the belt is correctly routed and seated on all pulleys. Rotate the tensioner again to allow for the belt to slip onto all pulleys and then release the tensioner again to regain correct tension on the belt.
