Hoses And Vacuum/Vapor Harnesses - Chrysler Crossfire 2007 Owner's Manual

Points to Remember
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 nor-
mally a result of moisture from rain, snow, or high
humidity accumulation on the radiator and being vapor-
ized when the thermostat opens, allowing hot water 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 bottle.
• Check coolant freeze point in the system.
• If frequent coolant additions are required, or if the
level in the recovery bottle does not drop when the
engine cools, the cooling system should be pressure
tested for leaks.
• Maintain a coolant concentration of a minimum of 50%
ethylene glycol Extended Life Coolant and high qual-
ity water with recommended antifreeze for proper
corrosion protection of your engine cooling system
that contains aluminum components.
• Make sure that the radiator and coolant bottle hoses
are not kinked or obstructed.
• Keep the front of the radiator clean. If your vehicle has
air conditioning, keep the front of the condenser clean,
also.
• 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 coolant performance, poor fuel
economy, and increased emissions.

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, checking, tears, cuts, abrasions,
and excessive swelling indicate deterioration of the rub-
ber.
Pay particular attention to the hoses nearest to high heat
sources such as the exhaust manifold. Inspect hose rout-
ing to be sure hoses do not touch any heat source or
moving component that may cause heat damage or
mechanical wear.
