Dodge 2005 PL Neon SRT4 - Manual (Page 161)

Points To Remember
NOTE: When the vehicle is stopped after a few kilome-
ters (a few miles) of operation, you may observe vapor
coming from the front of the engine compartment. This is
normally 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 recovery bottle.
• Check coolant freeze point in the system.
• If frequent coolant additions are required, the cooling
system should be pressure tested for leaks.
• Maintain coolant concentration at 50% HOAT ethylene
glycol engine coolant (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 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 gas
mileage, 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, tear, 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.
