REMOVAL
WAR NING :
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, "
OIL FILTER" .
CAUTION:
Do not spill engine oil on drive belts.
5. Remove connector bolt, and remove oil cooler.

Revision: 2006 January2006 M35/M45
CAUTION:
Do not spill engine oil to rubber parts such as drive belts and engine mounting insulator.
6. Remove water pipes, as 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. Make sure 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:
Be careful not to damage the mounting hole.
–Press in the relief valve until it reaches a depth of 7 mm (0.28 in) from end surface of oil pan (upper) using
approximately 10 mm (0.39 in) diameter drift.
CAUTION:
Carefully press in the relief valve by aligning its mounting hole side with the axle center so as not
to cause deformation.
INSTALLATION
Note the following, and install in the reverse order of removal.
Make sure that no foreign objects are adhering to the installation planes of oil cooler, oil pan (upper) (2WD
models) or oil cooler bracket (AWD models).
2WD Models
Align cutout on oil cooler with protrusion on oil pan (upper) side, and
tighten connector bolt.
AW D M od e ls
Align cutout on oil cooler with protrusion on oil cooler bracket side, and tighten connector bolt.
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, "
ENGINE OIL" and Refer to CO-11, "ENGINE COOLANT" .
2. Start the engine, and check there is no leaks of engine oil or engine coolant.

Regulator Valve Clearance
(Clearance) = (Regulator valve hole diameter) – (Regulator valve
outer diameter)
If the calculated value is out of the standard, replace oil pump
assembly.
CAUTION:
Coat regulator valve with engine oil.
Make sure that it falls smoothly into valve hole by its own
weight.

Precautions for Liquid GasketNBS004Q7
LIQUID GASKET APPLICATION PROCEDURE
1. Remove old liquid gasket adhering to the liquid gasket application surface and the mating surface.
Remove liquid gasket completely from the liquid gasket application surface, mounting bolts, and bolt
holes.
2. Wipe the liquid gasket application surface and the mating surface with white gasoline (lighting and heating
use) to remove adhering moisture, grease and foreign materials.
3. Attach liquid gasket tube to tube presser [SST: WS39930000
(—)].
Use Genuine RTV Silicone Sealant or equivalent. Refer to
GI-48, "
RECOMMENDED CHEMICAL PRODUCTS AND
SEALANTS" .
Within five minutes of liquid gasket application, install the mat-
ing component.
If liquid gasket protrudes, wipe it off immediately.
Do not retighten mounting bolts or nuts after the installation.
After 30 minutes or more have passed from the installation, fill
