Jeep Wrangler: Cooling System / Cooling System Notes
NOTE:
When the vehicle is stopped after a few miles/
kilometers 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 accumulating on
the radiator and being vaporized when the thermostat
opens, allowing hot engine coolant (antifreeze)
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 expansion bottle.
- Check the coolant freeze point in the radiator
and in the coolant expansion bottle. If engine
coolant needs to be added, the contents of
the coolant expansion bottle must also be
protected against freezing.
- If frequent engine coolant additions are
required, the cooling system should be pressure
tested for leaks.
- Maintain engine coolant concentration at a
minimum of 50% OAT coolant (conforming to
MS.90032) and distilled water for proper
corrosion protection of your engine which
contains aluminum components.
- Make sure that the coolant expansion bottle
overflow hoses are not kinked or obstructed.
- Keep the front of the radiator clean. If your
vehicle is equipped with air conditioning,
keep the front of the condenser clean.
- Do not change the thermostat for Summer or
Winter operation. If replacement is ever
necessary, install ONLY the correct type thermostat.
Other designs may result in unsatisfactory
engine cooling performance, poor gas
mileage, and increased emissions.
WARNING!
Do not open hot engine cooling system.
Never add engine coolant (antifreeze) when
the engine is overheated. Do not loosen or
remove the cap to cool an overheated
engine...
In order to ensure brake system performance,
all brake system components should be
inspected periodically. For the proper
maintenance intervals.
WARNING!
Riding the brakes can lead to brake failure
and possibly a collision...
