Removal and Installation

Oil Cooler: Removal and Installation

WARNING:

Be careful not to burn yourself, as the engine oil and engine coolant may be hot.

CAUTION:

- Do not spill engine coolant on the drive belt.
- Do not spill engine oil on rubber parts such as drive belts and engine mounting insulator.

NOTE:

When removing components such as hoses, tubes/lines, etc., cap or plug openings to prevent fluid from spilling.

Removal

1) Drain engine coolant from radiator and cylinder block. Refer to [Changing Engine Coolant] Service and Repair and [Engine Unit: Disassembly and Assembly] Disassembly and Assembly.

NOTE:
Perform this step only when removing water pipes and hoses.

2) Remove engine front under cover. Refer to [Front Bumper: Removal and Installation] Service and Repair.
3) Disconnect water hoses from oil cooler.

CAUTION:
Perform this step when engine is cold.

4) Remove oil filter. Refer to [Oil Filter: Removal and Installation] Service and Repair.
5) Remove connector bolt, oil cooler, and O-ring.

CAUTION:
Do not reuse O-ring.

Inspection after Removal

Oil Cooler

Check oil cooler for cracks. Check oil cooler for clogging by blowing compressed air through engine coolant inlet. If necessary, replace oil cooler assembly.

Relief Valve

Check relief valve for movement, cracks and breaks by pushing the ball. If necessary, replace relief valve.

Installation

Installation is in the reverse order of removal, paying attention to the following.

- If replacement of the relief valve is necessary, install the new relief valve in place by tapping it in using suitable tool.

CAUTION:
Do not reuse relief valve.

- Confirm that no foreign objects are adhering to the sealing surfaces of the oil cooler and oil pan (upper).





- Tighten connector bolt after aligning cutout on oil cooler with protrusion on oil pan (upper) side.

CAUTION:
Do not reuse O-ring.

Inspection after Installation

- Before starting engine, check oil/fluid levels including engine coolant and engine oil. If less than required quantity, fill to the specified level. Refer to [Recommended Fluids and Lubricants [for USA and Canada] [1][2]Maintenance ] (United States and Canada). Refer to [Recommended Fluids and Lubricants [for Mexico] ] (Mexico).
- Use procedure below to check for fuel leakage.
- Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leakage at connection points.
- Start engine. With engine speed increased, check again for fuel leakage at connection points.
- Run engine to check for unusual noise and vibration.

NOTE:
If hydraulic pressure inside timing chain tensioner drops after removal and installation, slack in the guide may generate a pounding noise during and just after engine start. However, this is normal. Noise will stop after hydraulic pressure rises.

- Warm up engine thoroughly to make sure there is no leakage of fuel, exhaust gas, or any oils/fluids including engine oil and engine coolant.
- Bleed air from passages in lines and hoses, such as in cooling system.
- After cooling down engine, again check oil/fluid levels including engine oil and engine coolant. Refill to specified level, if necessary.
