REMOVAL and INSTALLATION
See Figures 1, 2 and 3
Timing belts must always be handled carefully and kept completely free of dirt, grease, fluids and lubricants. This includes any accidental contact from spillage, fingerprints, rags, etc. These same precautions apply to the pulleys and contact surfaces on which the belt rides.The belt must never be crimped, twisted or bent. Never use tools to pry or wedge the belt into place. Such actions will damage the structure of the belt and possibly cause breakage.
- Disconnect the negative battery cable.
- Raise and safely support the vehicle.
- Remove the 4 crankshaft pulley bolts and remove the crankshaft pulley.
It is not necessary to loosen the crankshaft timing belt pulley bolt at the center.
- Remove the timing belt cover.
- Align the 4 timing marks by turning the crankshaft.
- Remove the timing belt tensioner, tensioner plate, tensioner spring, spring damper and timing belt.
After the timing belt is removed, never turn the camshaft or crankshaft independently. If turned, interference may occur among the pistons, and valves and parts related to the pistons and valves may be damaged.
- Inspect the timing belt for wear or cracks and replace as necessary. Check the tensioner for smooth rotation.
- Install the tensioner plate to the tensioner.
- Insert the lug of the tensioner plate into the hole of the tensioner.
- Install the tensioner, tensioner plate and spring. Do not tighten the tensioner bolt and stud, make the bolt hand tight only.
Be sure that plate movement is installed in the proper direction that causes the same directional movement of the tensioner inner race. If no movement between the plate and inner race occurs remove the tensioner and plate again and reinsert the plate lug into the tensioner hole.
- Check that the timing mark on the camshaft timing pulley is aligned with the V mark on the cylinder head cover. If not align the 2 marks by turning the camshaft by be careful not to turn it more than the allowable range.
- Check that the punch mark on the crankshaft timing belt pulley is aligned with the arrow mark on the oil pump case. If not align the 2 marks by turning the camshaft by be careful not to turn it more than the allowable range.
- With the 4 marks aligned, install the timing belt on the 2 pulleys in such a way that the arrow marks on the belt (if so equipped) coincide with the rotating direction of the crankshaft. In this state the No. 1 piston is at top dead center of its compression stroke.
- Install the tensioner spring and spring damper. To allow the belt to be free of any slack, turn the crankshaft 2 rotations clockwise after installing the tensioner spring and damper. After removing the belt slack, first tighten the tensioner stud to 8 ft. lbs.. (11 Nm) and then the tensioner bolt to 20 ft. lbs.. (27 Nm).
As a final check, confirm that both sets of timing marks are aligned properly.
- Ensure that the seal is between the water pump and the oil pump case. Install the timing belt outside cover. Torque the timing belt cover bolts to 8 ft. lbs.. (11 Nm).
- Install the crankshaft pulley. Fit the keyway on the pulley to the key on the crank timing belt pulley and tighten the 4 bolts to 8 ft. lbs.. (11 Nm).
- Lower the vehicle and install the negative battery cable.
