3. Disconnect harness connector at oil pressure switch (1), and
remove oil pressure switch (1) using deep socket (commercial
service tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge and hose [SST].
5. Start engine and warm it up to normal operating temperature.
6. Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80°C(176°F)]
If difference is extreme, check oil passage and oil pump for oil leaks.
7. After the inspections, install oil pressure switch as follows.
a. Remove old liquid gasket adhering to oil pressure switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine Liquid Gasket or equivalent.
c. After warming up engine, make sure that there is no leakage of engine oil with running engine.

WARNING:
lBe careful not to burn yourself, as the engine oil may be hot.
lProlonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Warm up engine, put vehicle horizontally and check for engine oil leakage from engine components. Refer
toLU-5, "
ENGINE OIL LEAKAGE".
2. Stop engine and wait for 10 minutes.
