2004 DODGE VIPER engine overheat

Adding Coolant
DO NOT remove the pressure cap when checking cool-
ant. When adding coolant or refilling system, a 50%
solution of ethylene glycol antifreeze coolant in water
should be used. Higher concentrations (not to exceed
65%) are required if temperatures below ±37ÉF are antici-
pated.
Use only high purity water such as distilled or deionized
water when mixing the water / antifreeze solution. The
use of lower quality water will reduce the amount of
corrosion protection in the engine cooling system.
NOTE:It is the owner's responsibility to maintain the
proper level of protection against freezing according to
the temperatures occurring in the area where the vehicle
is operated.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.
Cooling System Pressure Cap
The cap must be fully tightened to prevent loss of
coolant, and to insure that coolant will return to the
radiator from the coolant reserve tank.
The pressure cap should be inspected and cleaned if there
is any accumulation of foreign material on the sealing
surfaces.

WARNING!
The warning words ªDO NOT OPEN HOTº on the
pressure cap are a safety precaution. Never add
coolant to the radiator when the engine is over-
heated. Do not loosen or remove the pressure cap to
cool overheated engine. Heat causes pressure to
build up in the cooling system. To prevent scalding
or injury, do not remove the pressure cap while the
system is hot or under pressure.
Coolant Level
The coolant recovery bottle provides a visual method for
checking the coolant level without removing the pressure
cap.
With the engine warmed up, the coolant level should be
between MIN and MAX on the coolant recovery bottle.
