Coolant Surge Tank Pressure Cap; Engine Overheating - Chevrolet 2007 Avalanche Owner's Manual

Adding Coolant
If you need more coolant, add the proper
®
DEX-COOL coolant mixture at the surge tank,
but only when the engine is cool. See Cooling
System on page 464.
CAUTION:
{
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
it is hand-tight and fully seated.
