air conditioning DODGE CARAVAN 2004 4.G User Guide

²Check coolant freeze point in the radiator and in the
coolant recovery bottle. If antifreeze needs to be
added, contents of coolant recovery bottle must also be
protected against freezing.
²If frequent coolant additions are required, or if the
level in the coolant recovery bottle does not drop when
the engine cools, the cooling system should be pres-
sure tested for leaks.
²Maintain coolant concentration at 50% ethylene glycol
antifreeze (minimum) in water for proper corrosion
protection of your engine which contains aluminum
components.
²Make sure that the radiator and coolant recovery
bottle overflow hoses are not kinked or obstructed.
²Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean, also.
²Do 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.
²Increasing engine speed at idle does not reduce cool-
ant temperature! Put transmission in NEUTRAL and
let engine idle at normal engine idle speed.
Hoses And Vacuum/Vapor Harnesses
Inspect surfaces of hoses and nylon tubing for evidence
of heat and mechanical damage. Hard or soft spots,
brittle rubber, cracking, tears, cuts, abrasions, and exces-
sive swelling indicate deterioration of the rubber.
Pay particular attention to those hoses nearest to high
heat sources such as the exhaust manifold. Inspect hose
routing to be sure hoses do not come in contact with any
heat source or moving component which may cause heat
damage or mechanical wear.
322 MAINTAINING YOUR VEHICLE

The Heated Mirrors, Lower Instrument Panel Power
Outlet and Removable Floor Console, when in the front
position are fused with self resetting fuses that are only
serviceable by an authorized dealer. The power seats are
fused by a 30 Amp circuit breaker located under the
driver's seat. The Power Windows are fused by a 25 Amp
circuit breaker located under the instrument panel near
the steering column. If you experience temporary or
permanent loss of these systems see your authorized
dealer for service.VEHICLE STORAGE
If you are leaving your vehicle dormant for more than 21
days you may want to take steps to protect your battery.
You may:
²Remove the 20 Amp mini fuse in the Integrated Power
Module labeled Ignition-Off Draw (IOD).
²Or, disconnect the negative cable from the battery.
²Anytime you store your vehicle, or keep it out of
service (i.e. vacation) for two weeks or more, run the
air conditioning system at idle for about five minutes
in the fresh air and high blower setting. This will
insure adequate system lubrication to minimize the
possibility of compressor damage when the system is
started again.
