Inspection
ENGINE OIL LEVEL
NOTE:
Before starting engine, park vehicle on a level surface and check the engine oil level. If engine is already started, stop it and allow 10 minutes before checking.
1.Pull out oil level gauge and wipe it clean.
2.Insert oil level gauge and make sure the engine oil level is within the range (A) as shown.
3.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 that it is contaminated with engine coolant. Repair or replace damaged parts.
ENGINE OIL LEAKS
Check for engine oil leaks around the following areas:
- Oil pan (upper and lower)
- Oil pan drain plug
- Oil pressure switch
- Oil filter
- Intake valve timing control oil filter
- Intake 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 seals (front and rear)
OIL PRESSURE CHECK
WARNING:
- Be careful not to burn yourself, as engine oil may be hot.
- For M/T models, put the shift selector in the Neutral "N" position and apply the parking brake securely.
- For CVT models, put the shift selector in the Park "P" position.
1.Check engine oil level.
2.Remove engine undercover. Service and Repair.
3.Disconnect harness connector at oil pressure switch (1), and remove oil pressure switch (1) using a suitable tool.
- Oil pan (lower) (2)
-White arrow indicates : Front
CAUTION:
Do not drop or shock oil pressure switch.
4.Install oil pressure gauge and hose.
Tool number: ST-25051001 (J-25695-1)
: ST-25052000 (J-25695-2)
5.Start engine and warm it up to normal operating temperature.
6.Check oil pressure with engine running under no-load. [1][2]Engine Oil Pressure.
CAUTION:
If the difference between the measured pressure and the specification is extreme, check the oil passages and oil pump for leaks or blockages.
7.After the inspections, install oil pressure switch as follows:
a.Remove old liquid gasket adhering to oil pressure switch and engine.
b.Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine Silicone RTV Sealant or equivalent.Recommended Chemical Products And Sealants.
Oil pressure switch: 14.7 Nm (1.5 kg-m, 11 ft-lb)
c.Check engine oil level.
d.After warming up engine, make sure there are no engine oil leaks with engine running.
8.Install engine undercover. Service and Repair.
