The manufacturer recommends replacement of the timing belt on the Toyota Camry 2.2 model years 1990 through 1999 every 60,000 miles. This was determined after a study of the service history of this engine. The determining factor is the stretching of the belt after a period of time, which exceeds the ability of the tensioner to continue to apply the correct tension on the belt to prevent the belt from slipping. This motor has been defined as a freewheeling motor, which means that in the event of a failure the motor will not be damaged.
Raise and support the car on stands. Remove the right front wheel and the inner fender. Use the hydraulic jack to support the engine. Remove the right engine mount and bracket. Remove coolant reservoir and alternator bracket. Remove the top timing belt cover and rotate the engine clockwise until the mark on the crankshaft pulley aligns with the “O” mark located on the belt cover.
Make sure the hole in the camshaft groove aligns vertically with the mark on the shaft bearing cap behind the groove. Remove the crankshaft pin and, using the puller, remove the pulley. Remove the lower timing belt cover and belt guide washer. Loosen the tensioner bolt, pull the tensioner away from the belt and tighten the bolt slightly to hold the tensioner in place. Remove the timing belt.
Make sure the marks are aligned. Install the new belt starting at the crankshaft groove on the right side, and continue counterclockwise, keeping tension on the non-tensioned side.
Install belt guide washer, lower belt cover, and crankshaft pulley and pin. Torque the bolt to 80 foot-pounds. Make sure the notch in the crankshaft pulley aligns with the “O” mark on the pointer on the timing belt cover. Check the camshaft spline and make sure the hole is up and aligned with the mark on the bearing cap.
Release the tensioner and allow it to apply tension to the belt. Rotate the crankshaft twice and align the marks. If the tensioner has a silver spring, apply 31 foot-pounds of torque to the bolt. If the tensioner has a green spring, rotate the engine counterclockwise three teeth and torque the bolt to 31 foot-pounds. Install the components in the reverse order in which they were removed.
