1E-21 Engine Lubrication System: For F9Q Engine

For F9Q Engine

General Description

Engine Lubrication Description

S6JB0A1531001

The oil pump is of a gear type, and mounted downward in the cylinder block. Oil is drawn up through the oil pump 
strainer and passed through the pump to the heat exchanger, then the oil filter, and the filtered oil flow to each engine 
part.

Diagnostic Information and Procedures

Oil Pressure Check

S6JB0A1534001

NOTE
Prior to checking oil pressure, check the 
following.
• Oil level in oil pan

If oil level is low, add oil up to Full level 
mark (1) on oil level gauge referring to 
“Engine Oil and Filter Change (Diesel 
Engine Model) in Section 0B”.

• Oil quality

If oil is discolored or deteriorated, change 
it. For particular oil to be used, refer to 
“Engine Oil and Filter Change (Diesel 
Engine Model) in Section 0B”.

• Oil leaks

If leak is found, repair it.

 

1) Disconnect oil pressure switch coupler (1).
2) Remove oil pressure switch (2) from cylinder block.

3) Install special tools to vacated threaded hole of oil 

pressure switch.

Special tool
(A):  09915–77311
(B):  09915–77420
(C):  09915–77430

4) Start engine and warm engine up to normal 

operating temperature.

NOTE
Be sure to shift transmission gear shift lever 
in “Neutral” (shift select lever in “P” range for 
A/T vehicle), set parking brake and block 
drive wheels.

 

5) After warming up, measure oil pressure.

Oil pressure specification
Standard:
Approx. 120 kPa (1.2 kgf/cm

2

, 17.4 psi) at 1,000 r/

min
Approx. 350 kPa (3.5 kgf/cm

2

, 50.8 psi) at 3,000 r/

min
Limit:
Min. 70 kPa (0.7 kgf/cm

2

, 10.2 psi) at 1,000 r/min

Max. 400 kPa (4.0 kgf/cm

2

, 58.0 psi) at 3,000 r/min

6) After checking oil pressure, stop engine and remove 

special tool.

7) Tighten oil pressure switch (2) to specified torque.

Tightening torque
Oil pressure switch (a):  38 N·m (3.8 kgf-m, 27.5 
lb-ft)

8) Start engine and check oil pressure switch for oil 

leakage. If oil leakage is found, repair it.

9) Connect oil pressure switch coupler (1).
