•The ignition and fuel systems are highly important to the emission control system and to efficient engine operation. All
inspections and adjustments must be made by an Authorized Mazda Dealer.
•After the prescribed 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: This is a full function check of electrical systems such as lights, wiper and washer systems (including wiper blades),
and power windows.

COMPRESSION INSPECTIONA6E231402000201
Warning
•When the engine and the oil are hot, they can badly burn. Be careful not to burn yourself during
removal/installation of each component.
1. Verify that the battery is fully charged.
•Recharge it if necessary. (See G–6 BATTERY INSPECTION.)
2. Warm up the engine to the normal operating system temperature.
3. Stop the engine and allow it to cool off for about 10 min.
Warning
•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 fuel from spurting out of the glow plug
hole, do not ground the fuel injector terminal. (See F2–45 Fuel Line Safety Procedures.)
4. Disconnect the fuel injector connector.
Warning
•If the glow plug harness connector is connected, the glow plug harness and engine component
can come into contact and cause a short when the engine switch is ON. Disconnect the glow plug
harness connector before turning the engine switch on.
5. Remove the engine cover. (See B2–9 TIMING BELT REMOVAL/INSTALLATION.)
6. Remove all the glow plugs. (See F2–42 GLOW
PLUG REMOVAL/INSTALLATION.)

7. Install the SSTs into the glow plug hole.
8. Crank the engine and note the maximum gauge
reading.
9. Inspect each cylinder as above.
•If the compression in one or more cylinders is
low, pour a small amount of clean engine oil
into the cylinder and reinspect the
compression.
—If the compression increases, the piston,
the piston rings, or cylinder wall may be
worn and overhaul is required.
—If the compression stays low, a valve may
be stuck or improperly seated and
overhaul is required.
—If the compression in adjacent cylinders stays low, the cylinder head gasket may be damaged or the
cylinder head may be distorted and overhaul is required.

TIMING BELT REMOVAL/INSTALLATIONA6E231612040201
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. Remove the front tire (RH).
3. Remove the splash shield (RH).
4. Remove the washer tank.
5. Remove the drive belt. (See B2–4 DRIVE BELT REPLACEMENT.)
6. Remove the fuel filter with the fuel hose still connected and position the fuel filter so that it is out of the way.
( L.H.D.) (See F2–50 FUEL FILTER COMPONENT REMOVAL/INSTALLATION.)
7. Remove in the order shown in the table.
8. Install in the reverse order of removal.
9. Start the engine and inspect the pulleys and the drive belt for runout and contact.
