gauge registers no oil pressure. Repair the problem
before continuing.
4. A l l o w the engine to reach operating temperature
(fan comes on at least twice). The pressure should
be:
Engine Oil Temperature: 176°F (80°C)
Engine Oil Pressure:
At Idle: 70 kPa (0.7 kgf/cm 2 ,10 psi)
minimum
At 3,000 rpm: 340 kPa (3.5 kgf/cm 2 ,50 psi)
minimum
5. If oil pressure is NOT w i t h i n specifications, inspect
