NOTE: If the oil pressure warning indicator stays on
with the engine running, check the engine oil l
evel. If
the oil level is correct do the following test:
1. With the engine stopped, remove the oil pressure switch (see page 8-9), then install an oil pressure
gauge (A).
2. Start the engine. Shut it off immediately if the gauge registers no oil pressure. Repair the problem
before continuing.
3. Allow the engine to reach operating temperature (fan comes on at least twice). The pressure should
be:
4. If the oil pressure is out of specifications, inspect these items:
 Blocking of oil filter (see page 8-11).
 Blocking of oil screen.
 Inspect the oil pressure relief valve (see page 8-15).
 Inspect the oil pump (see page 8-17). 1. Warm up the engine.
2. Remove the drain bolt (A), and drain the engine oil.
3. Reinstall the drain bolt with a new washer (B).
4. Refill the engine with the recommended oil
(see page 3-2).
Do not overtighten.

2. Drain the engine coolant (see page 10-8).
3. Remove the drive belt auto-tensioner pulley
(see page 4-33).
4. Remove the crankshaft pulley (see page 6-16).
5. Remove the six bolts securing the water pump, then remove the water pump (A).
6. Inspect, and clean the O-ring groove and mating surface of the water passage.
7. Install the water pump with a new O-ring (B).
8. Clean up any spilled engine coolant.
9. Install the crankshaft pulley (see page 6-17).
10. Install the drive belt auto-tensioner pulley (see page 4-33).
11. Install the drive belt (see page 4-31).
12. Refill the radiator with engine coolant, and bleed the air from the cooling system with the heater

1. Disconnect the VTC oil control solenoid valve 2P
connector.
2. Remove the ground wire (A).
3. Remove the bolt (B) and the VTC oil control solenoid valve (C).
4. Check the VTC oil control solenoid valve strainer for clogging. If the strainer is clogged, replace the
VTC oil control solenoid valve.
5. Note the amount of valve opening by observing the position of the piston shoulder (A) through the
valve retard drain port. If you see the shoulder of
the piston, the valve is open and must be replaced. 6. Connect the battery positive terminal to VTC oil
control solenoid valve 2P connector terminal No. 2.
7. Connect the battery negative terminal to VTC oil control solenoid valve 2P connector terminal No. 1.
Appearance of inner valve (A) in the port should be
at least 1.2 mm (0.05 in.). If the inner valve does not
open, replace it; then go to step 8.
