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.

1. INSPECT RADIATOR CAP
NOTICE: When performing steps (a) and (b) below, keep
the radiator pump tester at an angle of over 30 above
the horizontal.
(a) Using a radiator cap tester, slowly pump the tester
and check that air is coming from the relief valve.
Pump speed:
1 push/ 3 seconds or more
NOTICE: Push the pump at a constant speed.
If air is not coming from the relief valve, replace the
radiator cap.
(b) Pump the tester several times and measure the relief
valve opening pressure.
Pump speed:
1 at time
1 push/1 second or less
2nd time or more
Any speed
Standard opening pressure:
74±103 kPa
(0.75±1.05 kgf/cm, 10.7 ± 14.9 psi)
Minimum opening pressure:
59 kPa (0.6 kgf/cm, 8.5 psi)
If the opening pressure is less than minimum, replace
the radiator cap.
RADIATOR
RADIATOR CLEANING
Using water or a steam cleaner, remove any mud or
dirt from the radiator core.
NOTICE: If using a high pressure type cleaner, be care±
full not to deform the fins of the radiator core. If the
cleaner nozzle pressure is 2,942 ± 3,432 kPa (30 ± 35
kgf/cm, 427 ± 498 psi), keep a distance of at least 40
cm (15.75 in.) between the radiator core and cleaner
