Inspection

ENGINE OIL LEVEL

1. Park vehicle on a level surface, wait 10 minutes before checking the engine oil level.
2. Pull out oil level gauge and wipe it clean.
3. Insert oil level gauge and make sure the engine oil level is within the range (A) as shown.
4. If it is out of range, adjust it.

ENGINE OIL APPEARANCE

• Check engine oil for white milky appearance or excessive contamination.
• If engine oil becomes white, it is highly probable that it is contaminated with engine coolant. Repair or replace damaged parts.

ENGINE OIL LEAKS

Check for engine oil leakage around the following areas:

• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Oil cooler
• Oil level sensor
• Engine oil temperature sensor
• Intake valve timing control solenoid valve
• Exhaust valve timing control solenoid valve
• Mating surface between front cover and rocker cover
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seals (front and rear)
• Front cover

OIL PRESSURE CHECK

WARNING:

• Be careful not to get burned, as engine oil may be hot.
• For engine oil pressure check, the transaxle should be in P (Park) (A/T and CVT models) or N (Neutral) (M/T models), and apply the parking brake securely.

1. Check engine oil level.
2. Disconnect harness connector at oil pressure sensor (2), and remove oil pressure sensor (2) from the cylinder block (1) using suitable tool.

CAUTION:

Do not drop or shock oil pressure switch.

    3.   Install oil pressure gauge and hose.

Tool number : ST25051001 (J256951)

: ST25052000 (J256952)

4. Start engine and warm it up to normal operating temperature.
5. Check oil pressure with engine running under noload.

   If difference between the specification and the tested pressure is extreme, check oil passage and oil pump for oil leaks.

   NOTE: When engine oil temperature is low, engine oil pressure becomes high.

6. After the inspections, install oil pressure switch as follows:

    a. Remove old liquid gasket from the oil pressure switch and engine.

    b. Apply liquid gasket and tighten oil pressure sensor to specification.

Use Genuine Silicone RTV Sealant or equivalent.

    c. Check engine oil level.

    d. After warming up engine, make sure there are no engine oil leaks.

Draining

WARNING:

• Be careful not to get burned, 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. Warm up the engine, park the vehicle on a level surface and check for engine oil leaks.
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove drain plug and then drain engine oil.

Refilling

1. Install drain plug with new copper sealing washer. CAUTION: - Be sure to clean drain plug and install new copper sealing washer. - Do not reuse copper sealing washer.
2. Refill with new engine oil. CAUTION: - The refill capacity depends on the engine oil temperature and drain time. Use these specifications for reference only. - Always use oil level gauge to determine the proper amount of engine oil in the engine.
3. Warm up engine and check area around drain plug and oil filter for engine oil leaks. Repair as necessary.
4. Stop engine and wait for 10 minutes.
5. Check the engine oil level.
