Adding Coolant
If you need more coolant, add the proper
®
DEX-COOL coolant mixture at the coolant
surge tank, but only when the engine is cool.

You can be burned if you spill coolant
on hot engine parts. Coolant contains
ethylene glycol, and it will burn if the
engine parts are hot enough. Do not
spill coolant on a hot engine.
When replacing the pressure cap, make sure to
turn the cap until it clicks.
