COOLING SYSTEM
SERVICE INFORMATION
GENERAL
I NOTICE I
Using coolant with silicate corrosion inhibitors may cause premature wear of water pump seals or blockage of radiator
passages. Using tap water may cause engine damage.
Add coolant at the reserve tank. Do not remove the radiator cap except to refill or drain the system.
Avoid spilling coolant on painted surfaces.
After servicing the system, check for leaks with a cooling system tester.
When the coolant temperature exceeds 120 °C (248 °F), the coolant temperature indicator will blink. The ECM will then
control the ignition and reduce engine speed to 9 mph (15 km/h). At this time, check the cooling system and engine for
leaks or damage. If everything is OK, then check the coolant indicator circuit and thermosensor (page 19-15).
