LU-4
< PRECAUTION >[QR25DE]
PRECAUTIONS
4. Apply the liquid gasket using suitable tool without breaks to the
specified location.
• If there is a groove for the liquid gasket application, apply the
liquid gasket to the groove.
• As for the bolt holes, normally apply the liquid gasket inside the holes. If specified, it should be applied outside the holes.
Make sure to read the text of this manual.
• Within five minutes of the liquid gasket application, install the mating component.
• If the liquid gasket protrudes, wipe it off immediately.
• Do not retighten after the installation.
• After 30 minutes or more have passed from the installation, fill the engine with the specified oil and coolant. Refer to MA-11,
"FOR USA AND CANADA : Fluids and Lubricants".
CAUTION:
If there are more specific instruct ions in the procedures contained in this manual concerning liquid
gasket applicatio n, observe them.

OIL LEVEL
• Before starting the engine, check the oil level. If t
he engine is already started, stop it and allow 10 minutes
before checking.
• Check that the oil level is within the range (A) on the oil level
gauge.
• If it is out of range, add oil as necessary.
ENGINE OIL APPEARANCE
• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes milky, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
OIL LEAKAGE
Check for oil leakage around the following areas:
•Oil pan
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Oil cooler
• Valve timing control cover and valve timing control solenoid valve
• Front cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seal (front and rear)
OIL PRESSURE CHECK
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Put the CVT shift selector in the Park "P" position.
1. Check engine oil level. Refer to OIL LEVEL.
2. Remove fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.
3. Disconnect oil pressure switch harness connector at oil pressure switch. Remove oil pressure switch and install Tools.
CAUTION:
Do not drop or shock oil pressure switch.
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load, using Tool. NOTE:

ENGINE OIL
• When engine oil temperature is low, engine oil pressure becomes high.
• If difference is extreme, check oil passage and oil pump for oil leaks.
6. After the inspections, install oil pressure switch as follows:
a. Remove old liquid gasket adhering to oil pressure switch.
b. Apply liquid gasket and tighten oil pressure switch to the specification. Use Genuine RTV Silicone Sealant or equivalent.
c. After warming up engine, make sure there are no engine oil leaks.
7. Install fender protector side cover (RH). Refer to EXT-26, "FENDER PROTECTOR : Exploded View"
.

WARNING:
• Be careful not to burn yourself, as the 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 oil. If skin contact is made, wash thoroughly with soap or hand cleaner as soon as
possible.
1. Position the vehicle so it is level on the hoist.
2. Warm up the engine and check for oil leaks from the engine.
3. Stop engine and wait for 10 minutes.
4. Remove the oil pan drain plug (1) and oil filler cap.
5. Drain the engine oil.
6. Install the oil pan drain plug with a new washer and refill the engine with new engine oil.
CAUTION:
• Be sure to clean the oil pan drain plug and install using a new washer.
• The refill capacity depends on the oil temper ature and drain time. Use these specifications for
reference only. Always use the oil level gauge to determine when the proper amount of oil is in
the engine.
7. Warm up the engine and check around the drain plug and oil filter for oil leaks.
8. Stop the engine and wait for 10 minutes.
9. Check the oil level using the oil level gauge. CAUTION:
Do not overfill the engine with engine oil. Engine oil pressure : Refer to
LU-18, "Oil Pressure"
Oil pressure switch : Refer to EM-28, "Exploded View"

- Measure the inner diameter of inner rotor (1) with inside microme-
ter (A).
- (Clearance) = (Inner rotor inner diameter) – (Oil pump inner rotor outer diameter)
• If measured/calculated values are out of the st andard, 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.
