You would better know how to change a belt for your car to save the money. Your car has 2 or more belts, including a timing belt and a fan belt. Cars have just one timing belt. Changing your timing belt requires some time and a few tools that you already have around your house.

It is vital for you to replace a timing belt before it wears out. Damage will occur if the timing belt wears down enough to break while the car is running. Cars require the timing belt to be changed every 105,000 miles. It’s a good idea to change the timing belt before the car reaches this point to avoid damage. There are no special tools needed to complete this job, and the recommended time is about three hours.

Jack the vehicle up and support it with jack stands. Remove the splash guard, the radiator, cooling fan, accessory belts, thermostat water hose, water pump pulley, distributor cover and the air intake tube on the valve cover.

Remove the crankshaft pulley bolt and the crankshaft pulley. Remove the top and bottom timing belt covers. You need to screw the crankshaft pulley bolt back in when you remove the covers. Turn the crankshaft until the Number 1 cylinder is on top dead center. The timing marks should be lined up. Timing marks are located on the camshaft pulleys and the crankshaft.

Loosen the timing belt tensioner nut. Turn the tensioner clockwise with an Allen wrench. Tighten the tensioner nut---this will keep the tensioner out of your way while you are removing and replacing the timing belt. Remove the timing belt.

You should make sure that the timing marks are still worked well. Starting at the crankshaft sprocket and moving counterclockwise, wrap the timing belt around the camshafts. Make sure the timing belt is tight between the sprockets on the opposite side of the tensioner.

Loosen the tensioner nut. Use an Allen wrench to keep the tensioner from moving while you loosen the nut. Turn the tensioner clockwise about 70 degrees and temporarily tighten the tensioner nut. Turn the crankshaft clockwise two complete turns. At the end of the second turn, the timing marks should line up again. If not, remove the belt and repeat Steps 4 and 5.

Put 22 pounds of pressure (with your hand) on the timing belt by pushing in on it at the half-way point between the tensioner and the left camshaft pulley. Hold the tensioner with an Allen wrench and loosen the tensioner nut. Insert a feeler gauge between the tensioner pulley and the belt. If your vehicle year is 1997 or older, the space between the belt and the pulley should be 0.014 ins thick by 0.5 ins. wide. If your vehicle is a 1998 or newer, the space should be 0.020 ins. thick by 0.5 ins. wide.

Turn the crankshaft clockwise (slowly) until the feeler gauge moves up to the 1 o'clock position of the tensioner pulley. It will be between the pulley and the belt. Hold the tensioner with the Allen wrench, then torque the tensioner nut to the following specifications

32-43 foot pounds of torque: 3.3 engines

32-43 foot pounds of torque: 3.0 engines up to 1996

58 to 65 foot pounds of torque: 3.0 engines from 1997 and on

Turn the crankshaft (slowly) clockwise to remove the feeler gauge. Remove the feeler gauge and turn the crankshaft until Number 1 cylinder is at top dead center and the timing marks line up. Use your hand to put pressure on the timing belt between the two camshaft sprockets. You should move the belt for 0.4 to 0.5 inches and if not , you need to do steps 6, 7 and 8 again.

Remove the crankshaft pulley bolt. Reinstall all of the components in the order you removed them. Replace the crankshaft pulley bolt when you replace the pulley. Torque the crankshaft pulley bolt to 95 foot pounds of torque if the year of your vehicle is 1993 or older. Torque the crankshaft pulley bolt to 150 foot pounds of torque if the year of your vehicle is 1994 or newer. Refill the Timing Belt Manufacturers.
