problem with engine overheating, see “Engine
Overheating”
in the Index.
A 50/50 mixture of water and DEX-COOL’
coolant will:
J
Give freezing protection down to -34°F (-37°C).
Give boiling protection up to 265 OF 129 ” C).
Protect against rust and corrosion.
Help keep the proper engine temperature.
Let the warning lights and gages work as
they should.

NOTICE:
When adding coolant, it is importrant that you use
O~Y DEX-CQOE~ (sficate-free) COQI~~.
If coolant other than DEX-COOL is added to the
system, premature engine, heater
core or
radiator corrosion may result.
Hw addition, the
engine coolant
will require change SQB~~F -- at
