Start the engine and allow it to warm up until the temperature of 

the coolant reaches 80

°C (176°F) to 90°C (194°F).

WARNING

Use care as oil could be hot.

1. Remove the engine oil filler cap.
2. Remove the drain plug to drain oil.
3. Install a new drain plug gasket so that it faces in the 

direction shown in the illustration, and then tighten the drain 
plug to the specified torque.

Tightening torque: 39 

± 5 N⋅m (29 ± 3 ft-lb)

4. Refill the specified quantity of oil.

Specified Engine Oil: Engine oils displaying ILSAC 
certification symbol ("Starburst" symbol) or conform-
ing the API classification SJ EC or SJ/CD EC

5. Apply a small amount of engine oil to the O-ring of the new 

oil filter.

6. Where the oil filter O-ring touches the oil pan flange, tighten 

the oil filter to the specified torque using the commercially-
available tool.

Tightening torque: Approximately 3/4 turn[14 

± 2 N⋅m 

(124 

± 18 in-lb)]

7. Install the drain plug and refill engine oil. (Refer to Engine 

Oil Replacement 

P.12-3

.) 

8. Rev the engine a few times, and check to be sure that no 

engine oil leaks from the installation section of the oil filter.

OIL PRESSURE CHECK

M1121002300272

Required Special Tool:
MD998054: Oil Pressure Switch Wrench
1. Check engine oil quantity.
2. Remove the oil pressure switch terminal.

CAUTION

Since sealant is applied to the thread of the oil pressure 
switch, take care not to damage the oil pressure switch 
when removing it.
3. Use special tool MD998054 to remove the oil pressure 

switch.

4. Install the oil pressure gauge.

NOTE: Use a 1/8 pipe thread adapter.

5. Run the engine to warm it.
6. After the engine has been warmed up, check that oil 

pressure is within the standard value.

Standard value:

At idle: 29 kPa (4.2 psi) or more
At 3,500 r/min: 294 

− 686 kPa (43 − 100 psi)

7. Remove the oil pressure gauge.
8. Apply the specified sealant 3M

ä AAD Part number 8672 or 

equivalent to thread of the oil pressure switch.
