Jeep Wrangler: Cooling System / Coolant Checks
Check the engine, battery (if equipped),
intercooler (if equipped), and Motor Generator
Unit (MGU) (if equipped) coolant (antifreeze)
protection every 12 months (before the onset of
freezing weather, where applicable). If the
engine, battery (if equipped), intercooler (if
equipped), and MGU (if equipped) coolant is
dirty or rusty in appearance, the system should
be drained, flushed and refilled with fresh OAT
coolant (conforming to MS.90032) by an
authorized dealer. Check the front of the A/C
condenser (if equipped) or radiator for any
accumulation of bugs, leaves, etc. If dirty, clean
by gently spraying water from a garden hose
vertically down the face of the A/C condenser (if
equipped) or the back of the radiator core.
Check the engine, battery (if equipped),
intercooler (if equipped), and MGU (if equipped)
cooling system hoses for brittle rubber,
cracking, tears, cuts, and tightness of the
connection at the coolant recovery bottle and
radiator. Inspect the entire system for leaks. DO
NOT REMOVE THE COOLANT PRESSURE CAP
WHEN THE COOLING SYSTEM IS HOT.
WARNING!
You or others can be badly burned by hot
engine coolant (antifreeze) or steam from
your radiator. If you see or hear steam
coming from under the hood, do not open
the hood until the radiator has had time to
cool...
NOTE:
Some vehicles require special tools to add
coolant properly. Failure to fill these systems
properly could lead to severe internal engine
damage...
