Inspection
 
 
ENGINE OIL LEVEL
noteBefore starting engine, put vehicle horizontally 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 check that the engine oil level is within the range shown in the figure.
3. If it is out of range, adjust it.
 
 
ENGINE OIL APPEARANCE
  • Check engine oil for white turbidity or heavy contamination.
  • If engine oil becomes turbid and white, 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 (upper and lower)
  • Drain plug
  • Oil pressure sensor
  • Oil temperature sensor
  • Oil filter
  • Oil cooler
  • Exhaust valve timing intermediate lock control solenoid valve
  • Exhaust valve timing control solenoid valve
  • Front cover
  • Mating surface between cylinder block and cylinder head
  • Mating surface between cylinder head and camshaft bracket
  • Mating surface between cylinder head and rocker cover
  • Mating surface between camshaft bracket and rocker cover
  • Mating surface between camshaft position sensor bracket and high pressure fuel pump
  • Crankshaft oil seals (front and rear)
 
 
OIL PRESSURE CHECK
warning
  • Be careful not to get burned, as engine oil may be hot.
  • When checking engine oil pressure, shift position should be “Parking position”, and apply parking brake securely.
 
 
1. Check engine oil level.
2. Disconnect harness connector at oil pressure sensor , and remove oil pressure sensor using a deep socket (commercial service tool).
: Engine front
cautionNever drop or shock oil pressure switch.
3. Install oil pressure gauge [SST: ST25051001] (A) and hose [SST: ST25052000] (B).
4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under no-load.
noteWhen engine oil temperature is low, engine oil pressure becomes high.
Engine oil pressure: Refer to Engine Oil Pressure.
If difference is extreme, check oil passage and oil pump for oil leakage.
6. After the inspections, install oil pressure switch as follows:
(1) Remove old liquid gasket adhering to oil pressure switch and engine.
(2) Apply liquid gasket and tighten oil pressure switch to specification.
Use Genuine RTV Silicone Sealant or an equivalent.
Tightening torque: Refer to Exploded View.
(3) Check engine oil level.
(4) After warming up engine, check that there is no leakage of engine oil with running engine.
