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 CO-11, "
Changing Engine Coolant" and
EM-123, "
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.

OIL COOLER
Revision: 2005 July 2005 FX
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
Inspect relief valve for movement, cracks and breaks by pushing ball. If replacement is necessary, remove
relief valve by prying it out with a suitable tool. Install a new relief valve in place by tapping it.
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 Model
Align cutout on oil cooler with protrusion on oil pan (upper) side, and
tighten connector bolt.
AW D M od e l
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.
3. Stop the engine and wait for 10 minutes.
4. Check the engine oil level and the engine coolant level again. Refer to LU-7, "
ENGINE OIL" and Refer to
CO-11, "
ENGINE COOLANT" .

REMOVAL
1. Remove oil pans (lower and upper) and oil strainer. Refer to EM-30, "OIL PAN AND OIL STRAINER" .
2. Remove front timing chain case and timing chain (primary). Refer to EM-64, "
TIMING CHAIN" .
3. Remove oil pump assembly.
INSTALLATION
CAUTION:
Before installation, apply new engine oil to the parts as instructed in the figure.
Note the following, and install in the reverse order of removal.

When installing, align crankshaft flat faces with oil pump inner rotor flat faces.
INSPECTION AFTER INSTALLATION
1. Check the engine oil level. Refer to LU-7, "ENGINE OIL" .
2. Start the engine, and check there is no leaks of engine oil.
3. Stop the engine and wait for 10 minutes.
4. Check the engine oil level and adjust the level. Refer to LU-7, "
ENGINE OIL" .
Disassembly and AssemblyABS004SZ
DISASSEMBLY
1. Remove oil pump cover.
2. Remove oil pump inner rotor and oil pump outer rotor from oil pump body.
3. After removing regulator valve plug, remove regulator valve spring and regulator valve.

INSPECTION AFTER DISASSEMBLY
Oil Pump Clearance

Measure the clearance with feeler gauge.
–Clearance between oil pump outer rotor and oil pump body
(position “1”)
–Tip clearance between oil pump inner rotor and oil pump outer
rotor (position “2”)

Measure the clearance with feeler gauge and straightedge.
–Side clearance between oil pump inner rotor and oil pump body
(position “3”)
–Side clearance between oil pump outer rotor and oil pump body
(position “4”)

Calculate the clearance between oil pump inner rotor and oil pump body as follows:
OIL PUMP BODY INNER DIAMETER
–Measure the inner diameter of oil pump body with inside
micrometer. (Position “5”)
OIL PUMP INNER ROTOR OUTER DIAMETER
–Measure the outer diameter of protruded portion of oil pump
inner rotor with micrometer. (Position “6”)
OIL PUMP INNER ROTOR TO OIL PUMP BODY CLEARANCE
–(Clearance) = (Oil pump body inner diameter) – (Oil pump inner rotor outer diameter)

If measured/calculated values are out of the standard, replace oil pump assembly. Standard : 0.114 - 0.260 mm (0.004 - 0.010 in)
Standard : Below 0.180 mm (0.007 in)
SLC932A
Standard : 0.030 - 0.070 mm (0.001 - 0.003 in)

Regulator Valve Clearance
(Clearance) = (Valve hole diameter) – (Regulator valve outer diame-

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.
ASSEMBLY
Note the following, and assemble in the reverse order of disassembly.

Install oil pump inner rotor with the groove faced to oil pump
cover side. Standard : 0.040 - 0.097 mm (0.0016 - 0.0038 in)
