ENGINE OIL
Inspection INFOID:0000000004784337
ENGINE OIL LEVEL NOTE:
Park vehicle on a level surface, wait 10 minutes and check the engine oil level.
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) shown.
3. If it is out of range, adjust it.
ENGINE OIL APPEARANCE • Check engine oil for white milky or excessive contamination.
• If engine oil becomes white, it is highly probable t hat it is contaminated with engine coolant. Repair or
replace damaged parts.
ENGINE OIL LEAKAGE Check for engine oil leakage around the following areas:
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure switch
• Oil filter
• Intake valve timing control solenoid valve
• Front cover
• Mating surface between cylinder head and camshaft bracket
• Mating surface between cylinder block and cylinder head
• Mating surface between cylinder head and rocker cover
• Crankshaft oil seals (front and rear)
• Oil filter (for intake valve timing control)
OIL PRESSURE CHECK WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• For engine oil pressure check the transaxle should be in “ Park position” (A/T models) or “Neutral
position” (M/T models), and apply the parking brake securely.
1. Check engine oil level.
2. Disconnect harness connector at oil pressure switch (2), and remove oil pressure switch (2) from the cylinder block (1) using
suitable tool.
CAUTION:
Never drop or shock oil pressure switch. PBIC3817E

Engine Oil Pressure " .
If difference 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 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. Refer to GI-42, " Recommended Chemical Product
and Sealant " .
c. Check engine oil level.
d. After warming up engine, make sure there are no leaks of engine oil with running engine.
Draining INFOID:0000000004784338
WARNING:
• Be careful not to burn yoursel f, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause ski n 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 vehicle on a level surface and check for engine oil leakage from engine compo- nents. Refer to LU-7, " Inspection " .
2. Stop the engine and wait for 10 minutes.
3. Loosen oil filler cap.
4. Remove drain plug and then drain engine oil.
Refilling INFOID:0000000004784339
1. Install drain plug with new washer. Refer to EM-39, " Exploded View " .
CAUTION:
Be sure to clean drain plug and install with new washer.
2. Refill with new engine oil. Engine oil specification and viscosity: Refer to MA-14, " Fluids and Lubricants " .
CAUTION:
• The refill capacity depends on the engine oi l temperature and drain time. Use these specifica-
tions for reference only.
• Always use oil level gauge to determine the pr oper amount of engine oil in the engine.
3. Warm up engine and check area around drain plug and oil filter for engine oil leakage.
4. Stop engine and wait for 10 minutes.
5. Check the engine oil level. Refer to LU-7, " Inspection " .

Drain and refill
With oil filter change Approximately 3.0 (3 1/8, 2 5/8)
Without oil filter change Approximately 2.8 (3, 2 1/2)
Dry engine (engine overhaul) Approximately 3.5 (3 3/4, 3 1/8) Engine speed rpm
Approximate discharge pressure* [kPa (bar, kg/cm 2
, psi)]
Idle speed More than 60 (0.60, 0.61, 9) 2,000 More than 270 (2.7, 2.8, 39)
