cooling DODGE DURANGO 2006 2.G User Guide

Adding Coolant
When adding coolant, or refilling the system, a minimum
solution of 50% recommended HOAT ethylene glycol
engine coolant (antifreeze) and distilled water should be
used. Use higher concentrations (not to exceed 70%) if
temperatures below34°F (37°C) are anticipated.
Use only high purity water such as distilled or deionized
water when mixing the water/engine coolant solution.
The use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
Please note that it is the owner’s responsibility to main-
tain the proper level of protection against freezing ac-
cording to the temperatures occurring in the area where
the vehicle is operated.
NOTE:Mixing coolant types will decrease the life of the
engine coolant and will require more frequent coolant
changes.WARNING!
Never add coolant to the radiator when the engine is
overheated. Do not loosen or remove pressure cap to
cool overheated engine. The coolant is under pres-
sure and severe scalding could result.
Coolant Pressure Cap
The coolant pressure cap must be fully tightened to
prevent loss of coolant, and to insure that coolant will
return to the radiator from the coolant recovery bottle.
The pressure cap should be inspected and cleaned if there
is any accumulation of foreign material on the sealing
surfaces.

WARNING!
The warning words “DO NOT OPEN HOT” on the
coolant pressure cap are a safety precaution. Heat
causes pressure to build up in the cooling system. To
prevent scalding or injury, do not remove the pres-
sure cap when the system is hot or under pressure.
Coolant Level
The coolant bottle system provides a quick visual method
for determining that the coolant level is adequate. With
the engine idling, and warmed to normal operating
temperature, remove the cap from the bottle, remove the
dipstick and wipe the excess coolant from it. Reinsert the
dipstick and remove. Observe the dipstick checking the
holes along the stem for coolant. Check the coolant level
whenever the hood is raised.The radiator normally remains completely full, so there is
no need to remove the pressure cap except checking
coolant freeze point or replacement with new antifreeze
coolant. Your service attendant should be advised of this.
When additional coolant is needed to maintain the
proper level, it should be added to the coolant bottle. Do
not overfill.
Points To Remember
A. Do not overfill the coolant bottle.
B. Check coolant freeze point in the radiator and in the
coolant bottle. If antifreeze needs to be added, contents of
coolant bottle also must be protected against freezing.
C. If frequent coolant additions are required, or if the
level in the coolant bottle does not drop when the engine
cools, the cooling system should be pressure tested for
leaks.

D. Maintain coolant concentration at 50% HOAT ethyl-
ene glycol engine coolant (minimum) and distilled water
for proper corrosion protection of your engine.
E. Make sure that the radiator and coolant bottle over-
flow hoses are not kinked or obstructed.
F. Keep the front of the radiator clean. If your vehicle is
equipped with air conditioning, keep the front of the
condenser clean also.
G. The thermostat should not be changed for summer or
winter operation. If replacement is ever necessary, install
ONLY the correct type thermostat. Other designs may
result in unsatisfactory cooling performance.

Fuel System Hoses And Vapor/Vacuum Harnesses
When the vehicle is serviced for scheduled maintenance,
inspect surface of hoses and nylon tubing for evidence of
heat and mechanical damage. Hard and brittle rubber,cracking, checking, tears, cuts, abrasions, and excessive
swelling suggest deterioration of the rubber. Particular
attention should be given to examining hose surfaces
nearest to high heat sources, such as the exhaust mani-
fold.
Insure nylon tubing in these areas has not melted or
collapsed.
Inspect all hose clamps and couplings to make sure they
are secure and no leaks are present.
NOTE:Fluids such as oil, power steering fluid, and
brake fluid are used during assembly plant operations to
ease the assembly of hoses to couplings. Therefore, oil
wetness at the hose-coupling area is not necessarily an
indication of leakage. Actual dripping of hot fluid when
systems are under pressure (during vehicle operation),
should be noted before hose is replaced based on leakage.
