Cooling System
Cooling System Maintenance
At the intervals shown in the Maintenance Schedules
Section of the manual, the system should be drained,
flushed and filled.
Inspection
Check engine coolant (antifreeze) protection every 12
months (before the onset of freezing weather, where
applicable). If coolant is dirty or rusty in appearance, the
system should be drained, flushed and refilled with fresh
coolant as specified.
Inspect the entire cooling system for leaks. Check the face
of the radiator for any accumulation of bugs, leaves, or
other foreign matter. If dirty, clean the radiator core with
a garden hose. With the engine OFF, gently spray water
from the back of the radiator core.
Check the coolant reserve tank tube for condition and
tightness or connections at the reserve tank and radiator.
Check the coolant pressure cap and coolant reserve
system for proper vacuum sealing. With the engine at
normal operating temperature, note the level of the
coolant in the coolant reserve tank. Without removing the
pressure cap (with the engine off), drain a small amount
of coolant from the radiator draincock. If the coolant level
in the reserve tank drops, the system is sealing properly.
Coolant Level
The coolant reserve system provides a quick visual
method of determining that the coolant level is adequate.
With the engine idling, and warmed to the normal
operating temperature, the level of the coolant on the
overflow bottle should be between the fluid level marks.
Check the coolant level whenever the hood is raised.
The radiator normally remains completely full, so there is
no longer a need to remove the coolant pressure cap
except for checking coolant freeze point or replacement
with new antifreeze coolant.
