Dodge 18681 Viper - Manual (Page 169)

WARNING!
The warning words “DO NOT OPEN HOT” 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.
