Checking Coolant - Chevrolet 2008 Silverado 1500 Pickup Owner's Manual

Checking Coolant

The coolant surge tank is located in the engine
compartment on the passenger's side of the vehicle.
See Engine Compartment Overview on page 5-14
for more information on location.
CAUTION:
{
Turning the surge tank pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. Never turn the surge tank pressure
cap — even a little — when the engine and
radiator are hot.
The vehicle must be on a level surface. When your
engine is cold, the coolant level should be at the
FULL COLD mark on the coolant surge tank.
If your vehicle has a low coolant sensor and the
LOW COOLANT LEVEL message comes on and
stays on, it means you are low on engine coolant.
See "LOW COOLANT LEVEL" under DIC Warnings
and Messages on page 3-66.
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 5-35
for more information.
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.
