WARNING:
 Be careful not to get burn yourself, as engine oil may be hot.
 Prolonged 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 thorough ly with soap or hand cleaner as
soon as possible.

2. Warm up the engine, and check for engine oil leakage from engine components. Refer to LU-5, "
Inspec-
tion".
3. Stop the engine and wait for 10 minutes.
4. Loosen oil filler cap and then remove drain plug.

WARNING:
Be careful not to get burn yourself, as en
gine oil and engine coolant may be hot.
NOTE:
When removing oil cooler only, step 2 is unnecessary.
1. Remove front engine undercover with power tool.
2. Drain engine coolant from radiator and cylinder block. Refer to CO-10, "
Changing Engine Coolant" and
EM-123, "

3. Disconnect water hoses from oil cooler.  When removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant from spill-
ing out.
 Remaining engine coolant in piping will come out. Use a tray to collect it.
CAUTION:
 Perform this step when the engine is cold.
 Do not spill engine coolant on drive belts.
4. Using oil filter wrench [SST: KV10115801 (J38956)], remove oil filter. Refer to LU-8, "

NOTE:
When engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure [Eng ine oil temperature at 80°C (176 °F)]
Uni t: kPa (kg/cm2, psi)
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 presser switch and engine.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Seal ant or equivalent. Refer to GI-44, "
