Caution
l Do not use alcohol- or methanol-based coolant.
l Use only soft (demineralized) water in the coolant
mixture.
1. Measure the coolant temperature and specific gravity with
a thermometer and a hydrometer.
2. Determine the coolant protection by referring to the graph
shown.
If the coolant protection is not proper, add water or coolant.

Warning
l Never open the radiator cap while the engine is hot.
l Wrap a thick cloth around the cap when loosening.
. Use caution when draining hot coolant.
Caution ..-
l Do not use alcohol- or methanol-based coolant.
l Use only soft (demineralized) water in the coolant
mixture.
1. Remove the radiator cap and loosen the drain plug.
2. Drain the coolant into a suitable container.
3. Flush the cooling system with water until all traces of color
are gone; then let the system drain completely.
4. Install the drain plug.
5. Fill with the proper amount and mixture of ethylene glycol
based coolant by referring to the table above.
Coolant capacity
MTX: 5.0 liters (5.3 US qt, 4.4 Imp qt)
ATX: 6.0 liters (6.3 US qt, 5.3 Imp qt)
6. Run the engine with the radiator cap removed until the up-
per radiator hose is hot.
7. With the engine idling, add coolant to the radiator until it
reaches the bottom of the filler neck.
8. Install the radiator cap.

INSPECTION
Radiator Cap Valve
1. Remove foreign material (such as water residue) from be-
tween the radiator cap valve and the valve seat.
2. Attach the radiator cap to a radiator cap tester (commer-
cially available) with the
SST. Apply pressure gradually to
74-103 kPa (0.75-l .05 kg/cm , 11-15 PSI).
3. Wait about 10 seconds. Verify that the pressure has not
decreased.
Negative Pressure Valve
1. Pull the negative pressure valve to open it. Verify that it
closes completely when released.
2. Check for damage on the contact surfaces and for cracked
or deformed seal packing.
3. Replace the radiator cap if necessary.

SYSTEM INSPECTION
1. Jump across the fan test (TFA) terminal and the ground
(GND) 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 wire 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. 97OC (207OF).
If it does, check the water thermoswitch.
(Refer to page E-16.)
FAN MOTOR
INSPECTION
Single-Speed Type
1. Check that the battery is fully charged.
2. Disconnect the fan motor connector.
3. Connect the battery and an ammeter to the fan motor con-
nectar.
4. Verify that current is as specified.

6.6 f 1 -
6.6 f 1 -
5. If current is not within specification and/or the fan does not
turn smoothly, replace the fan motor.
Two-Speed Type
1. Check that the battery is fully charged.
2. Disconnect the fan motor connector.
3. Connect the battery and an ammeter to the fan motor con-
nectors for low-speed inspection. 4. Verify that the fan motor operates smoothly at the standard
current.
Current (A): 8.8 + 10% MAX

BASIC INSPECTION
Engine Oil
1. Remove the engine oil level gauge and check the engine
oil level and oil condition.
2. Add or change the oil as necessary.
Coolant
Warning
l Never remove the radiator cap while the engine is
hot.
l Wrap a thick cloth around the cap before carefully
removing it.
1. Remove the coolant level gauge from the coolant reservoir.
2. Check that the coolant level is between the L and F marks
of the gauge.
3. Add coolant if necessary.
Battery
1. Check for corrosion on the terminals and for loose cable
connections. If necessary, clean the clamps and tighten
them firmly.
2. Check that the electrolyte level is between the UPPER LEV-
EL and LOWER LEVEL marks.
3. Add distilled water if necessary.
4. Check the specific gravity with a hydrometer.
Gravity: 1.27-l .29 (at 20% [68OF] )
