REMARKS
After 80,000 km or 48 months, continue to follow the described maintenance at the recommended intervals.
As for * marked items in this maintenance chart, note the following points.
* 1 Major service interval at 12 months120,OOO km (12,000 miles).
Lubrication service based on distance only 10,000 km (6,000 miles) not time.
*2 Adjust or inspect alternator and water pump drive belt, and power steering and air conditioner drive belt
if equipped.
“3 Replacement of the timing belt is required at every 100,000 km (60,000 mile). failure to replace the tim-
ing belt may result in damage to the engine.
“4 If the vehicle is operated under any of the following conditions, it is suggested that the engine oil and
oil filter be changed more often than the &commended intervals.
a) Driving in dusty conditions.
b) Extended periods of idling or low speed operation.
c> Driving for a prolonged periods in cold temperatures or regularly driving only short distances.
*5 If the vehicle is operated in very dusty or sandy areas, inspect and, if necessary, replace more oten
than at usual recommended intervals.
*6 This is a full function check of all electrical systems, i.e, all lights, washers (including condition of blades)
electric windows, sunroof, horn etc.
“7 Replace every two years.
If there has been continuous hard driving, mountain driving, or if the brakes are used extensively or the
vehicle is operated in extremely humid climates, the brake fluid should be changed annually.
Emission Control and Related Systems
The ignition and fuel systems are vitally important to the proper operation of the emission control and related
system, as well as for efficient engine operation. It is strongly recommended that all servicing related to these
systems be done by your Authorised Mazda Dealer.

COMPRESStON
If the engine exhibits low power, poor fuel economy, or poor idle, check the following:
1. Ignition system (Refer to Section G.)
2. Compression
3. Fuel system (Refer to Section F3.)
93G032-774 93GO32-712
1NSPECTION
1. Verify that the battery is fully charged. Recharge it if
necessary.
2. Warm up the engine to normal operating temperature.
3. Turn the engine OFF.
4. Remove all of the spark plugs.
5. Disconnect the ignition coil connector.
6. Connect a compression gauge to the No.7 spark plug hole.
7. Fully depress the accelerator pedal and crank the engine.
8. Record the maximum gauge reading.
9. Check each cylinder in the same manner.
Compression:
1,059 kPa (IO.8 kg/cm2, 154 psi)-300 rpm
Minimum:
785 kPa (8-O kg/cm2, 114 psi)-300 t-pm
Allowable difference between cylinders:
196 kPa (2.0 kglcm2, 28 psi) max.
IO. If the compression in one or more cylinders is low, pour a
small amount of engine oil into the cylinder and recheck
the compression.
(1) If the compression increases, the piston, piston rings,
or cylinder waII may be worn.
(2) If the compression stays tow, the valve may be stuck
or seating improperly.
(3) If the compression in adjacent cylinders stays low, the
cylinder head gasket may be defective or the cylinder
head distorted.
1 I. Connect the ignition coit connector.
12. Apply antiseize compound or molybdenum-based lubricant
to the spark plug threads.
73. Install the spark plugs.
Tightening torque:
15-23 N-m (1.5-2.3 m-kg, If-17 ft-Ib)

82 INSTALLATION
Steps after installation
1. If the engine oil was drained, refill with the specified amount and type of engine oil.
2. Fill the radiator with the specified amount and type of engine coolant.
3. Fill the transaxie with the specified amount and type of transaxle oil. (Refer to page J3-36.)
4. Connect the negative battery cable.
5. Start the engine and check the following:
(I) Engine oiI, transaxle oil, and engine coolant for leakage
(2) Ignition timing and idle speed
(3) Operation of emission control system
6. Perform a road test.
7. Recheck the engine oil and engine coolant levels.

Operation 1. When the coolant temperature exceeds 97OC (207*F), the water thermoswitch turns ON to close the No.7
relay, and connects the + I and -1 terminals of the fan motor
connector. The fan motor turns at low
speed (about 1,660 rpm).
2. When the coolant temperature exceeds 105OC (221 OF), the radiator thermoswitch turns ON, to close the
No.2 and No.3 relays, and connects
the +2 and -2 terminals of the fan motor connector. The fan mo-
tor turns at high speed (about 2,200 rpm).
3. if the vehicle is equipped with air conditioning, the cooling fan motor operates whenever the
NC switch
and the blower switch are on, regardless of
the coolant temperature. Also, when the A/C switch and the blower switch are on, the A/C retay closes
to operate the additional fan
motur.
Note
l The water thermoswitch and the cooling fan reIay are normally-open switches.
Checking cooling fan operation 1. Jump across the TFA and the GND terminals
of the diagnosis connector with a jumper wire.
2. Turn the ignition switch to ON and verify that the cooling fan operates smoothly.
Note
l When the water thermoswitch connector is disconnected, the cooling fan wiif not operate.

E-10 SYSTEM INSPECTION
1. Jump across the test fan (TFA) terminal and the ground
(GN D) terminal of the diagnosis connector.
2. Turn the ignition switch ON and verify that the fan operates.
If the fan does not operate, inspect the cooling fan system
components and wiring harness.
3. Remove the radiator cap and place a thermometer in the
radiator filler neck.
4. Start the engine.
5. Verify that the fan operates when the coolant temperature
reaches approx. 97*C (207°F).
If it does, check the water thermoswitch.
