Jeep Wrangler: Cooling System / Coolant Level
The coolant bottle provides a quick visual
method for determining that the coolant level is
adequate. With the engine OFF and cold, the
level of the engine coolant (antifreeze) in the
bottle should be between the ranges indicated
on the bottle.
The radiator normally remains completely full,
so there is no need to remove the radiator/
coolant pressure cap unless checking for
engine coolant freeze point or replacing
coolant. Advise your service attendant of this.
As long as the engine operating temperature is satisfactory, the coolant bottle
need only be
checked once a month.
When additional engine coolant is needed to
maintain the proper level, only OAT coolant that
meets the requirements of the manufacturer
Material Standard MS.90032 should be added
to the coolant bottle. Do not overfill.
Used ethylene glycol-based coolant (antifreeze)
OAT or HOAT, is a regulated substance requiring
proper disposal. Check with your local
authorities to determine the disposal rules for
your community...
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...
