Brake System - Jeep Liberty 2011 Owner's Manual

462 MAINTAINING YOUR VEHICLE
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 bottle.
• Check coolant freeze point in the radiator and in the
coolant recovery bottle. If engine coolant (antifreeze)
needs to be added, contents of coolant recovery bottle
must also be protected against freezing.
• If frequent engine coolant (antifreeze) additions are
required, or if the level in the coolant recovery bottle
does not drop when the engine cools, the cooling
system should be pressure tested for leaks.
• Maintain engine coolant (antifreeze) concentration at
50% HOAT engine coolant (antifreeze) (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 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 cooling performance, poor gas
mileage, and increased emissions.

Brake System

In order to assure brake system performance, all brake
system components should be inspected periodically.
Refer to the "Maintenance Schedule" for the proper
maintenance intervals.
