OIL PUMP

3. Loosen the oil pump bolts in the reverse order as shown.
4. Remove oil pump and O-rings.

CAUTION:

• Do not reuse O-rings.

• Do not disassemble oil pump.

INSTALLATION

1. Install new O-rings on the oil pan (upper) before installing the oil pump. Refer to

EM-34, "Exploded View"

.

CAUTION:

Do not reuse O-rings.

2. Install the oil pump.
3. Tighten the oil pump bolts to specification in the order shown.
4. Install timing chain and oil pump drive chain. Refer to

EM-51,

"Removal and Installation"

.

5. Refill engine with new engine oil. Refer to

LU-8, "Refilling"

.

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

MA-12, "Fluids and Lubricants"

.

• Use procedure below to check for fuel leaks.

• Turn ignition switch ON (with engine stopped). With fuel pressure applied to fuel piping, check for fuel leaks

at connection points.

• Start engine. With engine speed increased, check again for fuel leaks 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 leaks 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 spec-

ified level, if necessary.

• Summary of the inspection items:

*Power steering fluid, brake fluid, etc.

REMOVAL

WARNING:

Do not remove the radiator cap when the engine is hot. Serious burns could occur from high-pressure

engine coolant escaping from the radiator. Wrap a thick cloth around the radiator cap. Slowly turn it a

quarter of a turn to release built-up pressure. Carefully remove radiator cap by turning it all the way.

NOTE:

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

ing.
1. Drain engine oil. Refer to

LU-8, "Draining"

.

2. Drain engine coolant. Refer to

CO-8, "Draining Engine Coolant"

.

3. Remove oil filter. Refer to

LU-10, "Removal and Installation"

.

4. Remove water hoses from the oil cooler.
5. Remove oil cooler and O-ring.

CAUTION:

Do not reuse O-rings.

OIL COOLER

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.

Relief Valve

Inspect relief valve for movement, cracks and breaks by pushing the ball. If replacement is necessary, remove

the valve by prying it out using a suitable tool. Install a new valve by tapping it in place.

INSTALLATION

Installation is in the reverse order of removal.

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

• Tighten connector bolt after aligning cutout (1) on oil cooler with

protrusion (2) on oil pan (upper) side.

CAUTION:

• Do not reuse O-ring.

• Replace relief valve if removed.

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

MA-12, "Fluids and Lubricants"

.
