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.)
6. Disconnect the fuel hose. (See F2–45 BEFORE REPAIR PROCEDURE.)
7. Remove the front pipe. (See F2–57 EXHAUST SYSTEM REMOVAL/INSTALLATION.)
8. Remove the battery and tray. (See G–5 BATTERY REMOVAL/INSTALLATION.)
9. Remove the shift cable, select cable and clutch release cylinder related to the transaxle. (See J2–7 MANUAL
TRANSAXLE REMOVAL/INSTALLATION.)
10. Remove the clutch release cylinder.
11. Remove the vacuum hose and the heater hose.
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.)
14. Remove the joint shaft.
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.

NO.21 ENGINE NOISEA6E408018881223
Diagnostic Procedure
21 ENGINE NOISE
DESCRIPTION•Engine noise under hood.
POSSIBLE
CAUSE•Engine internal damage
•Timing belt displacement
•Fuel injector malfunction
•Loose attaching bolts or worn parts
•Improper drive belt tension
•Air leakage from intake-air system
•Incorrect injection timing
•Erratic signal from CKP sensor
•Erratic signal from CMP sensor
•Fuel pressure sensor or related circuit malfunction
•Boost sensor or related circuit malfunction
•Accelerator position sensor or related circuit malfunction
•MAF/IAT sensor or related circuit malfunction
•ECT sensor or related circuit malfunction
•EGR system or malfunction
•IAT sensor No.2 or related circuit malfunction
•Vacuum leakage
•Suction control valve malfunction (built-in supply pump)
•Air leakage from intake-air system
•Air in power steering fluid line
•Turbocharger operating noise
•Solenoid valve operating noise
Warning
The following troubleshooting flow chart contains the fuel system diagnosis and repair
procedures. Read the following warnings before performing the fuel system services:
•Fuel vapor is hazardous. It can 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 injury or death
and damage. Fuel can also irritate skin and eyes. To prevent this, always complete “BEFORE
REPAIR PROCEDURE” and “AFTER REPAIR PROCEDURE” described in this manual.
Note
•PCM checks fuel injection amount during a set interval while idling, and automatically corrects it to
maintain engine efficiency. It is normal that engine noise and vibration might be a little louder during
this process.
STEP INSPECTION RESULTS ACTION
1 Is squeal, click or chirp sound present? Yes Inspect engine oil level, solenoid valves installation or
drive belt.
No Go to next step.
2 Is rumble or grind sound present? Yes Inspect drive belt tension or power steering system
fluid level.
If okay, perform power steering fluid line air bleed.
No Go to next step.
3 Is rattle sound present? Yes Inspect location of rattle for loose parts.
No Go to next step.
4 Is hiss sound present? Yes Inspect for vacuum leakage and intake-air system
leakage.
No Go to next step.
5 Is rap or roar sound present? Yes Inspect exhaust system or loose parts.
No Go to next step.

OUTLINE OF CONSTRUCTIONA6E660201036201•The construction and operation of the steering system is essentially carried over from that of the current
Mazda6 (GG), except for the following features. (See Mazda6 Training Manual 3359-1*-02C.)
• Due to the addition of the MZR-CD (RF Turbo) engine, a gear-driven power steering oil pump has been
adopted. The operation of the oil pump is the same as that of the current Mazda6 (GG).
• The disassembly/assembly procedures for the steering gear and linkage of the newly equipped MZR-CD (RF
Turbo) engine, wagon and 4WD models are the same as that of the current Mazda6 (GG).

POWER STEERING FLUID INSPECTIONA6E661432040201Fluid Level Inspection
1. Inspect the power steering fluid level.
•Add fluid to the specified level as necessary.

Fluid Leakage Inspection
Caution
•If the steering wheel is kept in the fully turned position for more than 5 seconds, the fluid
temperature will rise excessively and adversely affect the oil pump.
1. Start the engine and let it idle.
2. Turn the steering wheel fully to the left and right to apply fluid pressure.
Note
•The points where fluid leakage may occur are indicated in the figure.
3. Inspect for fluid leakage.
•If fluid leakage is found, replace the related pipe or hose.
