REMOVAL

WARNING:
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 Changing Engine Coolant and EM-120, "Disassembly and Assembly".

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.
- Never spill engine coolant on drive belt.
4. Using oil filter wrench [SST: KV10115801 (J38956)], remove oil filter. Refer to Removal and Installation.

CAUTION:
Never spill engine oil on drive belt.
5. Remove connector bolt, and remove oil cooler.

CAUTION:
Never spill engine oil to rubber parts such as drive belt and engine mounting insulator.
6. Remove water pipes if necessary.

INSPECTION AFTER REMOVAL

Oil Cooler
Check oil cooler for cracks. Check oil cooler for clogging by blowing through engine coolant inlet. If necessary, replace oil cooler.

Relief Valve
Check relief valve with the following procedure.
- Press steel ball of relief valve using a clean plastic stick. Check that valve moves smoothly and proper spring repulsion is felt.
- Replace relief valve, if necessary, with the following procedure.
- Remove the relief valve by prying using a screwdriver.

CAUTION:

- Check that no foreign objects are adhering to the installation planes of oil filter and oil cooler bracket.

2WD Models
Align cutout (B) on oil cooler (1) with protrusion (C) on oil filter bracket side, and tighten connector bolt.






AWD Models
Align cutout (B) on oil cooler (1) with protrusion (A) on oil filter bracket side, and tighten connector bolt (3).






INSPECTION AFTER INSTALLATION
1. Check the engine oil level and the engine coolant level and add engine oil and engine coolant. Refer to Testing and Inspection and Inspection Changing Engine Coolant.
2. Start the engine, and check there is no leakage of engine oil or engine coolant.
3. Stop the engine and wait for 10 minutes.
4. Check the engine oil level and the engine coolant level again. Refer to Testing and Inspection and Inspection Changing Engine Coolant.
