Revision: 2005 July 2005 FX

Crankshaft oil seals (front and rear)

Camshaft position sensor (PHASE)
OIL PRESSURE CHECK
WARNING:

Be careful not to get burn yourself, as engine oil may be hot.

Oil pressure check should be done in “Parking position”.
1. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
2. Remove front engine undercover with power tool.
3. Disconnect harness connector at oil pressure sensor, and remove oil pressure sensor using deep socket (commercial ser-
vice tool).
CAUTION:
Do not drop or shock oil pressure switch.
4. Install the oil pressure gauge [SST] and hose [SST].
5. Start the engine and warm it up to normal operating temperature.
6. Check the engine oil pressure with engine running under no-load. NOTE:
When the engine oil temperature is low, the engine oil pressure becomes high.
Engine oil pressure [Engine oil temperature at 80 °C (176 °F)]
If difference is extreme, check engine oil passage and oil pump for engine oil leaks.
7. After the inspections, install oil pressure switch as follows:

Engine speed (rpm) Approximate discharge pressure [kPa (kg/cm2 , psi)]
Idle speed More than 98 (1.0, 14) 2,000 More than 294 (3.0, 43)

a. Remove old liquid gasket adhering to oil pressure switch and the mating surface.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-48, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .
c. After warming up engine, make sure there is no leakage of engine oil with running engine.
Changing Engine OilABS004SV
WARNING:

Be careful not to get burn yourself, as engine oil may be hot.

Prolonged and repeated contact with used engine oil may cause skin cancer; try to avoid direct
skin contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand
cleaner as soon as possible.
1. Remove front engine undercover with power tool.
2. Warm up the engine, and check for engine oil leakage from engine components. Refer to LU-7, "
ENGINE
OIL LEAKAGE" .
3. Stop the engine and wait for 10 minutes.
4. Loosen oil filler cap and then remove drain plug.
5. Drain engine oil.
6. Install drain plug with new washer. Refer to EM-30, "
OIL PAN AND OIL STRAINER" .
CAUTION:
Be sure to clean drain plug and install with new washer.
7. Refill with new engine oil. Engine oil specification and viscosity:
Refer to MA-12, "
RECOMMENDED FLUIDS AND LUBRICANTS" .
Engine oil capacity (Approximate):
Unit: (US qt, lmp qt)
CAUTION:

When filling engine oil, do not pull out oil level gauge.

The refill capacity depends on the engine oil temperature and drain time. Use these specifica-
tions for reference only.

Always use oil level gauge to determine the proper amount of engine oil in engine.
8. Warm up the engine and check area around drain plug and oil filter for engine oil leakage.
9. Stop the engine and wait for 10 minutes.
10. Check the engine oil level. Refer to LU-7, "
ENGINE OIL LEVEL" .
Oil pressure switch:
: 14.8 N·m (1.5 kg-m, 11 ft-lb)
Oil pan drain plug: : 34.3 N·m (3.5 kg-m, 25 ft-lb)
Drain and refill With oil filter change 4.7 (5, 4-1/8)

REMOVAL
WARNING:
Be careful not to get burn yourself, as engine oil may be hot.
1. Remove front engine undercover with power tool.
2. Using the oil filter wrench [SST: KV10115801 (J38956)], remove oil filter. Refer to LU-10, "
OIL FILTER" .
CAUTION:
Do not spill engine oil on drive belt.
3. Remove oil cooler connector bolt, and then oil cooler with water hoses connected.
4. Disconnect oil temperature sensor and oil pressure switch harness connectors.
5. Remove oil filter bracket from oil pan (upper).
6. Remove oil temperature sensor and oil pressure switch from oil filter bracket.
INSTALLATION
Note the following, and install in the reverse order of removal.

Install oil pressure switch and oil temperature sensor as follows:
–Remove old liquid gasket adhering to oil pressure switch and oil filter bracket.
–Apply liquid gasket and install oil pressure switch, and then oil temperature sensor with a new washer.
Use Genuine RTV Silicone Sealant or equivalent. Refer to GI-48, "
RECOMMENDED CHEMICAL
PRODUCTS AND SEALANTS" .

Align cutout on oil cooler with protrusion on oil filter bracket. Refer to LU-16, "INSTALLATION" .
