Engine Coolant - Chevrolet 2007 Corvette Owner's Manual

Engine Coolant

The cooling system in your vehicle is filled with
®
DEX-COOL engine coolant. This coolant is
designed to remain in your vehicle for five years
or 150,000 miles (240 000 km), whichever
occurs first, if you add only DEX-COOL
extended life coolant.
The following explains your cooling system
and how to add coolant when it is low. If you
have a problem with engine overheating,
see Engine Overheating on page 350.

whichever occurs first. Any repairs would
not be covered by your warranty. Always
