service attendant of this. As long as the engine operating
temperature is satisfactory, the coolant recovery bottle
need only be checked once a month.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant recovery
bottle. Do not overfill.
Points To Remember
NOTE: When the vehicle is stopped after a few kilome-
ters (a few miles) of operation, you may observe vapor
coming from the front of the engine compartment. This is
normally a result of moisture from rain, snow, or high
humidity accumulation on the radiator and being vapor-
ized when the thermostat opens, allowing hot water to
enter the radiator.
If an examination of your engine compartment shows no
evidence of radiator or hose leaks, the vehicle may be
safely driven. The vapor will soon dissipate.
Do not overfill the coolant recovery bottle.
Check coolant freeze point in the system.
If frequent coolant additions are required, the cooling
system should be pressure tested for leaks.
Maintain coolant concentration at 50% HOAT ethylene
glycol engine coolant (minimum) and distilled water
for proper corrosion protection of your engine which
contains aluminum components.
Make sure that the radiator and coolant recovery
bottle hoses are not kinked or obstructed.
Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean,
also.
