Timing Belt: Service and Repair






REMOVAL
1. Remove coolant reserve tank.
2. Remove crankshaft pulley.
3. Follow removal procedure outlined in illustration, noting the following.

NOTE: Place the removed power steering oil pump in a place where it will not be a hindrance when removing and installing the timing belt, and tie it with a cord.

4. Remove the power steering oil pump from the bracket with the hose attached.
5. Place a garage jack against the engine oil pan with a piece of wood in between, jack up the engine so that the weight of the engine is no longer being applied to the engine mount bracket, and then remove the engine mount bracket.

CAUTION: Do not rotate the camshaft or crankshaft after removing the timing belt, or valve components may be damaged. Always align timing marks before removing timing belt.





6. Align timing marks. Loosen the timing belt tensioner to remove timing belt.
7. When the tensioner is removed from the engine, it is necessary to compress the plunger into the tensioner body.

NOTE: Index the tensioner in the vise the same way it is installed on the engine. This is to ensure proper pin orientation when the tensioner is installed on the engine.





8. Place the tensioner into a vise and slowly compress the plunger.
9. When the plunger is compressed into the tensioner body, install a pin through the body and plunger to retain plunger in place until tensioner is installed.

INSTALLATION
1. Follow removal procedure in reverse order noting the following.





2. Set the crankshaft sprocket to TDC by aligning the sprocket with the arrow on the oil pump housing.
3. Set the camshafts timing marks together by aligning notches on sprockets.
4. Move the crankshaft to 1/2 notch before TDC.





5. Install the timing belt. Starting at the crankshaft, go around the water pump sprocket, idler pulley, camshaft sprockets and then around the tensioner pulley.
6. Move the crankshaft sprocket to TDC to take up belt slack. Install the tensioner to block but do not tighter, fasteners.





7. Using a torque wrench on the tensioner pulley, apply 28 Nm (21 ft. lbs.) of torque to tensioner.
8. With torque being applied to the tensioner pulley, move the tensioner up against the tensioner pulley bracket and tighten fasteners to 31 Nm (23 ft. lbs.).
9. Pull the tensioner plunger pin. Pretension is correct when the pin can be removed and installed.
10. Rotate the crankshaft 2 revolutions and check the alignment of the timing marks. If marks are not aligned correctly, do it again.
11. Perform engine adjustments. Refer to Powertrain Management.
