5. Loosen the camshaft holder bolts two turns at a time, in a crisscross pattern. Then remove the
camshaft holders from the cylinder head.
6. Lift the camshafts out of the cylinder head, wipe them clean, then inspect the lift ramps. Replace the
camshaft if any lobes are pitted, scored, or
excessively worn.
7. Clean the camshaft journal surfaces in the cylinder head, then set the camshafts back in place. Place a
plastigage strip across each journal.
8. Install the camshaft holders, then tighten the bolts to the specified torque as shown in step 2.
9. Remove the camshaft holders. Measure the widest portion of plastigage on each journal.
 If the camshaft-to-holder clearance is within the service limits, go to step 11.
 If the camshaft-to-holder clearance is beyond the service limit, and the camshaft has been replaced,
replace the cylinder head.
 If the camshaft-to-holder clearance is beyond the service limit, and the camshaft has not been
replaced, go to step 10. 10. Check the total runout with the camshaft supported
on V-blocks.
 If the total runout of the camshaft is within the service limit, replace the cylinder head.
 If the total runout is beyond the service limit, replace the camshaft, and recheck the camshaft-
to-holder oil clearance. If the oil clearance is still
beyond the service limit, replace the cylinder
head.

9. Apply a thin coat of new engine oil to the outside of
the new valve guide. Install the guide from the
camshaft side of the head, use the valve guide
driver to drive the guide in to the specified installed
height (A) of the guide (B). If you have all 16 guides
to do, you may have to reheat the head. 10. Coat both valve guide reamer, 5.5 mm and the
valve guide with cutting oil.
11. Rotate the reamer clockwise to the full length of the valve guide bore.
12. Continue to rotate the reamer clockwise while removing it from the bore.
13. Thoroughly wash the guide in detergent and water to remove any cutting residue.
14. Check the clearances with a valve (see page 6-55). Verify that a valve slides into the intake and
exhaust valve guides without sticking.
15. Inspect the valve seating, if necessary renew the valve seat using a valve seat cutter (see page 6-58).

1. Disconnect the 2P connectors from the radiator fan motor and the A/C condenser fan motor.
2. Test the motor by connecting battery power to terminal No. 2 and ground to terminal No. 1.
3. If the motor fails to run or does not run smoothly, replace it (see page 10-19). Replace the thermostat if it is stuck in the open position
at room temperature.
To test a closed thermostat:
1. Suspend the thermostat (A) in a container of water. Do not let the thermostat and the thermometer (B)
touch the bottom of the hot container.
2. Heat the water, and check the temperature with a thermometer. Check the temperature when the
thermostat first opens, then check the temperature
again when the thermostat is fully open.
3. Measure the lift height of the thermostat when it is fully open. If it thermostat is not within the
specification, replace it.
