Procedures

Engine Oil: Inspection

OIL Level
^ Before starting the engine make sure the vehicle is parked on a flat and level surface, then check the oil level. If the engine is already running, turn it off and allow 10 minutes before checking.





^ Pull out oil level gauge and wipe clean.
^ Insert oil level gauge.
^ Check that the oil level is within the low (L) and high (H) range as indicated on the dipstick.
^ If the engine oil level is out of range, add oil as necessary.

CAUTION:
Do not overfill the engine with oil.

Engine OIL Appearance
^ Check the engine oil for a white milky appearance or excessive contamination.
^ If the engine oil is milky, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.

Engine OIL Leakage
Check for engine oil leakage around the following area.
^ Oil pan
^ Oil pan drain plug
^ Oil pressure switch
^ Oil filter
^ Oil cooler
^ Intake valve timing control cover and intake valve timing control solenoid valve
^ Front cover
^ Mating surface between cylinder block and lower cylinder block
^ 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 the engine and engine oil may be hot.
^ Put the A/T shift selector in the Park (P) position (A/T models) or Neutral position (M/T models), and apply parking brake securely.

1) Check engine oil level.
2) Remove engine under cover.
3) Disconnect the oil pressure switch harness connector.
4) Remove oil pressure switch using a suitable tool.

CAUTION:
Do not drop or shock oil pressure switch.

5) Install Tools.





Tool numbers: ST25051001 (J-25695-1)
: ST25052000 (J-25695-2)

6) Start the engine and warm it up to normal operating temperature.
7) Check the engine oil pressure with engine running under no-load.

CAUTION:
^ If the difference is extreme, check the oil passages and oil pump for leaks and blockages.
^ It is impossible to replace or adjust oil pump because oil pump is manufactured with balancer unit. If any malfunction is found on oil pump, replace balancer unit as an assembly.

8) After the inspections, install oil pressure switch as follows:
a) Remove old liquid gasket adhering to oil pressure switch and the engine.
b) Apply liquid gasket and tighten oil pressure switch to the specification.
Use Genuine RTV Silicone Sealant or equivalent.

Oil pressure switch torque: 14.7 Nm (1.5 kg-m, 11 ft-lb)

c) After warming up engine, make sure there is no leakage of engine oil with running engine.
