Warning
•Fuel vapor is hazardous. It can very easily ignite, causing serious injury and damage. Always keep
sparks and flames away from fuel.
•Fuel line spills and leakage are dangerous. Fuel can ignite and cause serious injures or death and
damage. Fuel can also irritate skin and eyes. To prevent this, always complete the “Fuel Line
Safety Procedure”. (See F2–45 Fuel Line Safety Procedures.)
1. Disconnect the negative battery cable.
2. Drain the engine coolant, engine oil, and transaxle oil.
3. Remove the radiator.
4. Remove the engine cover. (See B2–9 TIMING BELT REMOVAL/INSTALLATION.)
5. Remove the air cleaner and air hose. (See F2–36 INTAKE-AIR SYSTEM REMOVAL/INSTALLATION.)

12. Disconnect the P/S oil pump pressure pipe and P/S oil pump relief hose from the P/S oil pump side. (See N–16
POWER STEERING OIL PUMP (MZR-CD (RF Turbo)) REMOVAL/INSTALLATION.)
Note
•The P/S oil pump will not be removed from the engine.
13. Remove the A/C compressor with the pipe still connected. Position the A/C compressor so that it is out of the
way. Use wire or rope to secure it. (See U–11 A/C COMPRESSOR REMOVAL/INSTALLATION.)

15. Remove the front drive shaft (LH) from the transaxle.
16. Remove in the order indicated in the table.
17. Install in the reverse order of removal.
18. Fill the engine coolant, engine oil, and transaxle oil.
19. Bleed the air from the fuel line. (See F2–45 AFTER REPAIR PROCEDURE.)
20. Start the engine and:
•Inspect the pulleys and the drive belt for runout and contact.
•Inspect the engine oil, engine coolant transaxle oil, P/S fluid, and fuel for leakage.
•Inspect the idle speed. (See F2–34 IDLE SPEED INSPECTION.)
21. Perform a road test.
22. Reinspect the engine oil, engine coolant, transaxle oil, and P/S fluid levels.

Warning
•Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your
skin by washing with soap and water immediately after working with engine oil.
•Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the
engine oil have cooled.
1. Disconnect the negative battery cable.
2. Remove the under cover.
3. Remove the oil pressure switch.
4. Screw the SST into the oil pressure switch
installation hole.
5. Warm up the engine to normal operating
temperature.
6. Run the engine at the specified speed, and note
the gauge readings.
•If the pressure is not as specified, inspect for
the cause and repair or replace if necessary.

Note
•The oil pressure can vary with oil viscosity and temperature.
7. Stop the engine and wait until it is cool.
8. Remove the SST.
Caution
•Any sealant stuck at the end of the oil pressure switch can cause operation malfunction of the oil
pressure switch.
Be sure there is no sealant at the end of the oil pressure switch.
9. Apply silicone sealant to the oil pressure switch
threads as shown.
10. Install the oil pressure switch.

Warning
•Hot engines and engine oil can cause severe burns. Turn off the engine and wait until it and the
engine oil have cooled.
•A vehicle that is lifted but not securely supported on safety stands is dangerous. It can slip or fall,
causing death or serious injury. Never work around or under a lifted vehicle if it is not securely
supported on safety stands.
•Continuous exposure to USED engine oil has caused skin cancer in laboratory mice. Protect your
skin by washing with soap and water immediately after working with engine oil.
Caution
•In case you spill engine oil on the front pipe, wipe it off completely. If you fail to wipe the spilled
oil, it will produce fumes because of the heat.
1. Position the vehicle on level ground.
2. Remove the the oil filler cap.
3. Remove the under cover.
4. Remove the oil pan drain plug.
5. Drain the engine oil into a container.
6. Install the oil pan drain plug with a new the washer.
Tightening torque

Note
•The amount of residual oil in the engine can vary with the replacement method, oil temperature, etc. Verify
the oil level after engine oil replacement.
7. Refill the engine oil with the specified type and amount, then install the oil filler cap.
