Replace a 1998 Toyota Camry 2.2L Timing Belt
The timing belt, which transfers engine rotation from the camshaft to the oil pump, water pump and crankshaft, is the basic utility that powers all of the engine accessories. Once the belt is damaged or broken, the engine accessories aren't able to function, so the belt should be replaced at the earliest sign of abnormal wear or function. Do-it-yourself mechanics with average automotive experience can complete this task on a 1998 Toyota Camry with a 2.2-liter engine within a few hours.
Instructions
1. Raise the right front of the vehicle with a hydraulic jack. Slide a jack stand under the frame rail near the right front of the car. Unscrew the wheel lug nuts with a socket wrench. Pull the rim and tire from the car. Pull the splash shield inside the fender away from the car to remove it.
2. Unscrew the retaining bolt attaching the coolant reservoir to the body with a socket wrench. Detach the hose from the top of the reservoir. Pull the reservoir up from the retaining bracket and out of the engine compartment.
3. Unscrew the pivot bolt and locking bolt on the alternator with a socket wrench. Loosen the drive belt adjusting bolt near the alternator with a socket wrench, then slip the belt off of the alternator pulley, air conditioning compressor pulley and crankshaft pulley. Remove it from the engine compartment.
4. Remove any remaining mounting bolts holding the alternator and alternator bracket in place, then pull the alternator and bracket from the engine compartment.
5. Unscrew the adjustment bolt attaching the power steering pump to the power steering pump bracket with a socket wrench. Pivot the pump toward the engine to loosen the drive belt. Slip the belt off of the power steering pump pulley. This step is only needed for models equipped with power steering.
6. Unscrew the three mounting bolts holding the engine cover in place with a socket wrench. Turn the fastener on the center of the cover counterclockwise to remove it, then pull the cover up from the engine and out of the engine compartment.
7. Pull the spark plug boots from the spark plugs. Grasp the lower portion of the boot, not the thin wire portion, then pull the boot from the socket. Label the location of each spark plug wire. Remove the spark plugs with a socket wrench and spark plug socket.
8. Place a flat block of wood on the top of the hydraulic vehicle jack. Slide the jack under the right side of the engine and raise the engine slightly. Do not raise the engine by the oil pan. Remove the right engine mount and engine support rod mounting bolts with a socket wrench, then pull the engine mount and support rod from the engine and frame.
9. Unscrew the wiring harness bracket retaining bolt attaching the harness to the upper timing cover with a socket wrench. Set the wiring aside. Unscrew the upper timing belt cover mounting bolts with a socket wrench and remove the upper timing belt cover and gasket. Loosen the upper idler pulley with a socket wrench and detach the spring from the pulley with pliers.
10. Unscrew the retaining bolts holding the flywheel inspection cover in place on models equipped with manual transmissions with a socket wrench. Pull the inspection cover away the transmission. Place a large screwdriver between the spokes of the crankshaft pulley to stop it from rotating and unscrew the crankshaft pulley bolt with a socket wrench.
11. Attach a vibration damper puller to the crankshaft pulley. Rotate the center of the pulley with a socket wrench to draw the pulley away from the crankshaft. Remove the pulley and the puller from the engine compartment.
12. Unscrew the lower timing belt cover mounting bolts with a socket wrench and remove the lower timing belt cover and gasket. Slip the timing belt off of the camshaft and crankshaft sprockets and the water pump, oil pump and idler pulleys. Slip the new belt onto the pulleys and sprockets, ensuring the sprockets do not rotate during removal and installation of the drive belt.
13. Place the lower timing belt cover and gasket against the engine block and install the retaining bolts with a socket wrench. Guide the crankshaft pulley onto the crankshaft. Place a large screwdriver between the spokes of the pulley to stop it from rotating. Install the crankshaft pulley bolt and tighten it to 80 foot-pounds.
14. Attach the spring to the upper idler pulley with pliers. Tighten the upper idler pulley with a socket wrench. Attach the wiring harness and wiring harness bracket to the upper timing cover with a socket wrench.
15. Attach the inspection cover to the transmission on models equipped with manual transmissions and install the retaining bolts with a socket wrench. Place the upper timing belt cover and gasket against the engine block and install the retaining bolts with a socket wrench.
16. Position the right front engine mount and engine support rod into place and tighten the mounting bolts with a torque wrench. Tighten the engine mount bolts to 49 foot-pounds and the support rod mounting bolts to 47 foot-pounds. Lower the hydraulic jack and remove the block of wood from the top of the jack.
17.Install the spark plugs with a torque wrench and spark plug socket. Tighten each spark plug to 13 foot-pounds. Push the boot of each spark plug wire firmly onto each spark plug.
18. Place the engine mounting cover over the spark plugs on the top of the engine. Install the fasteners in the center of the cover by turning it clockwise. Tighten the three mounting bolts holding the engine cover in place with a socket wrench.
19. Slip the power steering pump belt over the power steering pump pulley. Pivot the power steering pump away from the engine to increase tension on the pump belt, then tighten the adjustment bolt attaching the power steering pump to the power steering pump bracket with a socket wrench. This step is only needed for models equipped with power steering.
20. Install the alternator bracket and tighten the mounting bolts with a socket wrench. Position the alternator against the bracket and install the mounting bolts with a socket wrench. Thread the pivot bolt and locking bolt on to the alternator, but do not tighten them.
21. Slip the drive belt over the air conditioning compressor pulley, crankshaft pulley and alternator pulley. Tighten the pivot bolt and locking bolt with a socket wrench. Tighten the belt adjusting nut near the alternator with a socket wrench.
22. Place the coolant reservoir tank against the body and install the mounting bolt with a socket wrench. Push the coolant hose onto the fitting on top of the reservoir.
23. Push the splash shield against the edges of the fender to engage the retaining clips. Guide the tire and rim over the lug nut studs and install the lug nuts with a torque wrench. Tighten each lug nut to 76 foot-pounds.
24. Place the hydraulic jack under the from of the car to support it. Remove the jack stand then lower the car with the hydraulic jack.
