OIL COOLER

LU-13

< REMOVAL AND INSTALLATION >

5. Remove oil cooler bolts in reverse numerical order.

6. Remove oil cooler and gasket.

CAUTION:

• Be careful not to get burned when engine and engine oil may be hot.

• When removing, prepare a shop cloth to absorb any engine oil leaks or spillage.

• Completely wipe off any engine oil that adheres to engine and vehicle.

7. Remove relief valve.

INSTALLATION

Installation is in the reverse order of removal.
1. Tighten oil cooler to specification as shown.

CAUTION:

• Do not reuse gasket.

• Ensure gasket and oil cooler sealing surface is free from dust, flaws, or deformation.

• Ensure water hose assembly is installed without kinks or areas of collapse.

• Replace relief valve, if removed.

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

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.

INSPECTION AFTER INSTALLATION

1. Check the engine oil level and the engine coolant level and add engine oil and engine coolant. Refer to

LU-7, "Inspection"

and

CO-8, "Inspection"

2. Start the engine, and check that there are no leaks of engine oil or engine coolant.
3. Stop the engine and wait for 5 minutes.
4. Check the engine oil level and the engine coolant level again. Refer to

LU-7, "Inspection"

and

CO-8,

"Inspection"

INSPECTION AFTER DISASSEMBLY

OIL PUMP CLEARANCE

• Measure the clearance using a suitable tool (A).

- Clearance between outer rotor (B) and front cover (C)

- Tip clearance between inner rotor and outer rotor (B)

• Measure the clearance using suitable tools (A/B).

- Side clearance between inner rotor (3) and front cover (1)

- Side clearance between outer rotor (2) and front cover (1)

• Calculate the clearance between oil pump inner rotor and oil pump body as follows:

- Measure the outer diameter of protruded portion of inner rotor (1)

using a suitable tool (A).

OIL PUMP

- Measure the inner diameter of inner rotor (1) using a suitable tool

(A).

- (Clearance) = (Inner rotor inner diameter) – (Oil pump inner rotor outer diameter)

• If measured/calculated values are out of the standard, replace front cover and oil pump assembly.

REGULATOR VALVE TO OIL PUMP COVER CLEARANCE

- (Clearance) = (Regulator valve hole (1) diameter) – (Regulator

valve (2) outer diameter)

• If the calculated value is out of the standard, replace front cover

and oil pump assembly.

CAUTION:

• Coat regulator valve with engine oil.

• Make sure that it falls smoothly into valve hole by its own

weight.

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-11, "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 are 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.
