INSPECTION
1, Remove the intake manifold bracket.
2. Remove the oil pressure switch.
3. Screw the SST into the oil pressure switch installation hole.
4. Warm up the engine to normal operating temperature.
5. Run the engine at 1,000 rpm and 3,000 rpm, and note the
gauge reading.
Oil pressure:
196-294 kPa (2.0-3.0 kg/cm2, 28-43 psi)-1,000 rpm
294-392 kPa (3.0-4.0 kg/cm2, 43-57 psi)-3,000 rpm
6. If the pressure is not as specified, check for the cause and
repair. (Refer to Troubleshooting Guide.)
7. Remove the SST and install the oil pressure switch.
Tightening torque:
12-18 N-m (1.2-l .8 m-kg, 104-156 in-lb)
8. Install the intake manifold bracket.

Free length: 45.5mm (1.791 in) -
Rotor Clearance
1. Measure the following clearances. Replace the rotor if
necessary.
Tooth tip clearance: 0.20mm (0.0079 in) max.
Outer rotor to pump body clearance:
0.22mm (0.0087 in) max.
Side clearance: 0.14mm (0.0055 in) max.
Assembly Note
Oil seal
1, Apply a small amount of clean engine oil to the lip of a new
oil seal.
2. Push the oil seal slightly in by hand,
Caution
l The oil seal must be pressed in until it is flush with
the edge of the oil pump body.
-’
3. Press the oil seal in evenly with a suitable pipe.
Oil seal outer diameter: 44mm (1.73 in)

Warning
l Never remove the radiator cap while the engine is
hot.
l Wrap a thick cloth around the cap when removing it.
l When removing the radiator cap, loosen it slowly
to the first stop until the pressure in the radiator is
released, and then remove it.
03UOEX~006
Coolant Level (Engine cold)
1. Verify that the coolant level is near the radiator filler neck.
2. Remove the coolant level gauge and check the coolant level.
Coolant Quality
1. Verify that there is no buildup of rust or scale around the
radiator cap or radiator filler neck.
2. Verify that coolant is free of oil. Replace the coolant if
necessary.
Coolant Leakage
1. Connect a radiator tester (commercially available) and the
SST to the radiator filler neck.
2. Apply
103 kPa (1.05 kg/cm2, 15 psi) pressure to the
system.
3. Verify that the pressure is held.
If not, check for coolant leakage.
