SCHEDULED MAINTENANCE
•To ensure efficient operation of the engine and all systems related to emission control, the ignition and fuel systems must
be serviced regularly. It is strongly recommended that all servicing related to these systems be done by an authorized
Mazda Dealer.
•After the described period, continue to follow the described maintenance at the recommended intervals.
•Refer below for a description of items marked* in the maintenance chart.
*1: If the vehicle is operated under any of the following conditions, change the engine oil and oil filter every 10,000 km
(6,250 miles) or shorter.
a. Driving in dusty conditions.
b. Extended periods of idling or low speed operation.
c. Driving for long period in cold temperatures or driving regularly at short distance only.
*2: Also inspect and adjust the power steering and air conditioner drive belts, if installed.
*3: If the brakes are used extensively (for example, continuous hard driving or mountain driving) or if the vehicle is
operated in extremely humid climates, change the brake fluid annually.
*4: If the vehicle is operated in very dusty or sandy areas, clean and if necessary, replace the air cleaner element more
often than the recommended intervals.
*5: Replacement of the timing belt is required at every 100,000 km (62,500 miles).
Failure to replace the timing belt may result in damage to the engine.
*6: Replacement of the timing belt is required at every 120,000 km (75,000 miles).
Failure to replace the timing belt may result in damage to the engine.
*7: If the vehicle is operated under any of the following conditions, change the rear differential oil
every 40,000 km (25,000 miles).
a. Towing a trailer or using a car - top carrier
b. Driving in dusty, sandy or wet condition
c. Extended periods of idling or low speed operation
d. Repeated short trips of less than 16 km (10 miles)
*8: If this component has been submerged in water, the oil should be changed.

•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 injuries 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. Remove the timing belt. (See B2–9 TIMING BELT REMOVAL/INSTALLATION.)
2. Remove the vacuum pump. (See P–13 VACUUM PUMP REMOVAL/INSTALLATION (MZR-CD (RF
TURBO)).)
3. Remove the P/S oil pump with the oil hose still connected. Position the P/S oil pump so that it is out of the way.

5. Remove all the glow plugs. (See F2–42 GLOW PLUG REMOVAL/INSTALLATION.)
6. Remove in the order shown in the table.
7. Install in the reverse order of removal.
8. Inspect valve clearance. (See B2–5 VALVE CLEARANCE INSPECTION.)
9. Inspect the engine oil level.
•If necessary, add oil. (See D–8 ENGINE OIL INSPECTION.)
10. Inspect the compression. (See B2–8 COMPRESSION INSPECTION.)
11. Start the engine and:
(1) Inspect the pulleys and the drive belt for runout and contact.
(2) Inspect the engine oil, engine coolant, and fuel leakage.
