The serpentine belt is ok until you see fraying, or missing sections of the linear grooves(the ones running lengthwise.) Cracking across those grooves is ok, as long as none of that groove is missing. If you see cracking on the backside (smooth side) you also want to replace. Glazing of either side, where the rubber is smooth, shiny, and hard also warrants changing.

Serpentine belt diagram for a 2003 Chevy unpalatable 4.3


Pop the hood of the car and locate the serpentine belt routing diagram. The diagram on the 2003 Chevrolet Impala is on top of the fan shroud. The diagram will be a picture of all of the accessory pulleys and how the serpentine belt is routed among the pulleys. This diagram will give you the exact direction for routing the new belt onto the pulleys. If you cannot find a serpentine belt routing diagram, take a notepad and pen and draw out the exact routing diagram of the old belt across the pulleys.

  • 2 Locate the serpentine belt tensioner. It is located below the alternator on the left front side of the engine. The tensioner on the 3.4 liter, 3.5 liter and the 3.9 liter engines will require a 3/8 ratchet to release the belt tensioner. The 3.8 liter engine will require a ratchet and a 15 mm socket for the belt tensioner. Rotate the belt tensioner clockwise to loosen and remove the belt from the belt tensioner pulley.
  • 3 Slide the old belt from the belt tensioner pulley. Remove the belt from the remaining pulleys and pull the belt from the engine compartment.
  • 4 Route the new belt across the crankshaft pulley first. The crankshaft pulley is the big pulley on the bottom of the engine in the center. Then route the serpentine belt across the remaining pulleys as directed by the serpentine belt routing diagram. Leave the belt tensioner pulley for last.
  • 5 Rotate the belt tensioner clockwise again to relieve the tension and slide the new belt across the top of the belt tensioner pulley. Release the belt tensioner and the belt will tighten up as the tensioner applies pressure to the belt. Make sure the new belt is properly seated in all the pulleys.
  • 6 Crank the engine and inspect the belt again to make sure that it stays seated in the pulleys.

    What mi interval is a timing belt required?


    Are you sure you have a belt, not a metal chain? To my knowledge all the Chrysler V6 engines use a timing chain, which should last the life of the motor. Ask your local auto parts store, they can tell you for sure.
    (Don't confuse the timing belt/chain with the serpentine drive belt which runs the air conditioner, water pump, power steering pump, etc. The serpentine belt is always rubber and is visible at the front of the engine (your left as you face the car with the hood open). This should be inspected once a year beginning at 5 years or 60,000 miles, and replaced once it starts showing cracks or wear. If you have never replaced yours, you are due for it now. I just replaced mine on my 2005 T&C with 63,000 miles.)

    If you do have a rubber timing belt, I would replace it every 6 years or 60,000 miles (whichever is first) unless the owner's manual calls for a different interval.
    Many engines today have "negative valve clearance", which means if the timing belt breaks, the piston will run into the valve, possibly bending the valves. This means a full overhaul of the motor, which is *much* more expensive than replacing the belt.

    A metal timing chain is internal to the engine and lubricated by engine oil, and will not break like a rubber belt can. It will last the life of the motor (150,000 miles or more).

    The Service Engine Soon light came on. Could this be something serious or just a reminder that I just hit 80,000 miles and I should take it in. I had the oil changed and fluid levels checked and belts and...


    Service engine soon light is alerting you that a code is stored in your computer. If not checked out it could be something that will have an effect on other parts and may cost mor to fix. Most auto parts stores will check it for free.
