1. REMOVE RADIATOR CAP
CAUTION:
To avoid the danger of being burned, do not remove the ra-
diator cap while the engine and radiator are still hot, as fluid
and steam can be blown out under pressure.
2. INSPECT RADIATOR CAP
NOTICE:
If the radiator cap has contaminations, always rinse
it with water.
Before using a radiator cap tester, wet the relief valve
and pressure valve with engine coolant or water.
When performing steps (a) and (b) below, keep the
tester at an angle of over 30° above the horizontal.
(a) Using a radiator cap tester, slowly pump the tester and
check that air is coming from the vacuum valve.
Pump speed: 1 push/(3 seconds or more)
NOTICE:
Push the pump at a constant speed.
If air is not coming from the vacuum valve, replace the radiator
cap.
(b) Pump the radiator cap tester, and measure the relief valve
opening pressure.
Pump speed: 1 push within 1 second
NOTICE:
This pump speed is for the first pump only (in order to close
the vacuum valve). After this, the pump speed can be re-
duced.
Opening pressure:
Standard74 to 103 kPa (0.75 to 1.05 kgf/cm2,10.7 to 14.9 psi)
Minimum59 kPa (0.6 kgf/cm2, 8.6 psi)
HINT:
Use the tester's maximum reading as the opening pressure.
If the opening pressure is less than minimum, replace the radia-
tor cap.
3. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap tes-
ter.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
2, 17.1 psi), and check that
the pressure does not drop.
If the pressure drops, check the hoses, radiator or water pump
for leaks. If no external leaks are found, check the heater core,
cylinder block and head.

INSPECTION
1. CHECK ENGINE OIL QUALITY
Check the oil for deterioration, entry of water, discoloring or thin-
ning.
If the quality is visibly poor, replace the oil.
Oil grade:
API grade SL Energy±Conserving or ILSAC multi-
grade engine oil.
2. CHECK ENGINE OIL LEVEL
The oil level should be between the ºLº and ºFº marks on the dip-
stick.
If low, check for leakage and add oil up to the ºFº mark.
NOTICE:
Do not fill with engine oil above the ºFº mark.
3. REMOVE ENGINE UNDER COVER
4. REMOVE OIL PRESSURE SWITCH
5. INSTALL OIL PRESSURE GAUGE
6. WARM UP ENGINE
Allow the engine to warm up to normal operating temperature.
7. CHECK OIL PRESSURE
Oil pressure:
At idle29 kPa (0.3 kgf/cm2, 4.2 psi) or more
At 3,000 rpm294 ± 588 kPa (3.0 ± 6.0 kgf/cm2, 43 ± 85 psi)
8. REMOVE OIL PRESSURE GAUGE
9. REINSTALL OIL PRESSURE SWITCH
(a) Apply adhesive to 2 or 3 threads of the oil pressure switch.
Adhesive:
Part No. 08833±00080, THREE BOND 1344, LOCTITE
242 or equivalent
(b) Reinstall the oil pressure switch.

INSPECTION
1. INSPECT RELIEF VALVE
Coat the valve with engine oil and check that it falls smoothly
into the valve hole by its own weight.
If it doesn't, replace the relief valve. If necessary, replace the oil
pump assembly.
2. INSPECT DRIVE AND DRIVEN ROTORS
(a) Place the drive and driven rotors into the oil pump body.
(see page LU±14)
(b) Inspect the rotors for the body clearance.
Using a feeler gauge, measure the clearance between
the drive and driven rotor tips.
Standard tip clearance:
0.060 to 0.180 mm (0.0024 to 0.0071 in.)
Maximum tip clearance: 0.18 mm (0.0071 in.)
If the tip clearance is greater than maximum, replace the rotors
as a set.
(c) Inspect the rotors for the side clearance.
Using a feeler gauge and precision straight edge, mea-
sure the clearance between the rotors and precision
straight edge.
Side clearance:
0.030 to 0.090 mm (0.0012 to 0.0035 in.)
Maximum body clearance: 0.09 mm (0.0035 in.)
If the side clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(d) Inspect the rotor for the body clearance.
Using a feeler gauge, measure the clearance between
the driven rotor and body.
Standard body clearance:
0.250 to 0.325 mm (0.0098 to 0.0128 in.)
Maximum body clearance: 0.325 mm (0.0128 in.)
If the body clearance is greater than maximum, replace the ro-
tors as a set. If necessary, replace the oil pump assembly.
(e) Remove the drive and drive rotors.
