Chrysler 2005 Town and Country manual Hoses And Vacuum/Vapor Harnesses

•Check 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.

•If 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.

•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 overflow 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, also.

MAINTAINING YOUR VEHICLE 399

•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.

•Increasing 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.
