2. CHECK ENGINE COOLANT QUALITY
There should not be any excessive deposits of rust or
scales around the radiator cap or radiator filler hole,
and the engine coolant should be free from oil.
If excessively dirty, replace the engine coolant.
3. REPLACE ENGINE COOLANT
(a) Remove the radiator cap.
CAUTION: To avoid the danger of being burned, do not
remove It while the engine and radiator are still hot, as
fluid and steam can be blown out under pressure.
(b) Drain the engine coolant from the radiator drain cock
and engine drain plug. (Engine drain plug at the right
rear of cylinder block.)
(c) Close the drain cock and plug.
Torque (Engine drain plug):
13 N±m (130 kgf±cm, 9 ft±lbf)
(d) Slowly fill the system with coolant.
Use a good brand of ethylene±glycol base
coolant and mix it according to the
manufacturer 's directions.
Using engine coolant which includes more than
5096 ethylene±glycol (but not more than 7096) is
recommended.
NOTICE:
wDo not use a alcohol type coolant.
wThe engine coolant should be mixed with demineral±
ized water or distilled water.
Capacity (w/ Heater):
8.3 liters (6.7 US qts, 5.5 Imp.qts)
(a) Reinstall the radiator cap.
(f) Warm up the engine and check for leaks.
(g) Recheck the engine coolant level and refill as neces±
sary.
COOLANT CHECK AND
REPLACEMENT
1. CHECK ENGINE COOLANT LEVEL AT RESERVOIR
TANK
The engine coolant level should be between the
ºLOWº and ªFULLº lines.
If low, check for leaks and add engine coolant up to
the ªFULLº line.
± 5S±FE ENGINECOOLING SYSTEMEG1±241

2. INSPECT COOLING SYSTEM FOR LEAKS
(a) Fill the radiator with coolant and attach a radiator cap
tester.
(b) Warm up the engine.
(c) Pump it to 118 kPa (1.2 kgf/cm
, 17.1 psi), and check
that the pressure does not drop.
If the pressure drops, check the hoses, radiator or
water pump for leaks. If no external leaks are found,
check the heater core, cylinder block and head.
RADIATOR REMOVAL
1. DISCONNECT NEGATIVE (±) TERMINAL CABLE
FROM BATTERY
CAUTION: Work must be started after 90 seconds from
the time the ignition switch is turned to the ªLOCKº
position and the negative (±) terminal cable is discon±
nected from the battery.
