Be careful not to get burn yourself, as engine 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-11, "
Changing Engine Coolant" and
EM-124, "
DISASSEMBLY" .
NOTE:
Perform this step when removing water pipes.
3. Disconnect water hoses from oil cooler.
When removing oil cooler only, pinching water hoses near oil cooler to prevent engine coolant from
spilling 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-10, "

(position “1”)
–Tip clearance between oil pump inner rotor and oil pump outer
rotor (position “2”)
Measure the clearance with feeler gauge and straightedge.
–Side clearance between oil pump inner rotor and oil pump body
(position “3”)
–Side clearance between oil pump outer rotor and oil pump body
(position “4”)
Calculate the clearance between oil pump inner rotor and oil pump body as follows:
OIL PUMP BODY INNER DIAMETER
–Measure the inner diameter of oil pump body with inside
micrometer. (Position “5”)
OIL PUMP INNER ROTOR OUTER DIAMETER
–Measure the outer diameter of protruded portion of oil pump
inner rotor with micrometer. (Position “6”)
OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE
–(Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)
If measured/calculated values are out of the standard, replace oil pump assembly. Standard : 0.114 - 0.260 mm (0.004 - 0.010 in)
