Oil Pressure Check
| WARNING | To avoid danger of being burned, do not touch exhaust manifold when exhaust system is hot. When servicing, be sure to perform it after exhaust system has cooled down. |
Note. Prior to checking oil pressure, check the followings. Oil level in oil pan. If oil level is low, add oil up to Full level hole on oil level gauge. Oil quality. If oil is discolored, or deteriorated, change it. For particular oil to be used. See ENGINE OIL & FILTER CHANGE . Oil leaks. If leak is found, repair it.

- Remove exhaust manifold cover and then oil pressure switch (1) from cylinder block.
- Install special tools (Oil pressure gauge) to vacated threaded hole. Special tool (A): 09915-77310 (B): 09915-78211 CAUTION: Be careful not to make special tools touch exhaust manifold when installing because exhaust manifold becomes very hot.
- Start engine and warm it up to normal operating temperature. NOTE: Be sure to place transmission gear shift lever in "Neutral" (shift selector lever to "P" range for A/T model), and set parking brake and block drive wheels.
- After warming up, raise engine speed to 4000 rpm and measure oil pressure. Oil pressure specification: 390-470 kPa (3.9-4.7 kg/cm 2 , 55.5-66.8 psi) at 4000 rpm
- After checking oil pressure, stop engine and remove oil pressure gauge.
- Before reinstalling oil pressure switch, be sure to wrap its screw threads with sealing tape (1) and tighten switch to specified torque. Tightening torque Oil pressure switch (a): 14 N.m (1.4 kg-m, 10.5 lb-ft) NOTE: If sealing tape edge is bulged out from screw threads of switch, cut it off.
- Start engine and check oil pressure switch for oil leakage.
