Adding Coolant; Radiator Pressure Cap - Buick 2008 Allure Owner's Manual

The vehicle must be on a level surface when checking
the coolant level.
When the engine is cold, the coolant level should be at
the COLD FILL line or a little higher. The COLD
FILL line is near the bottom of the recovery tank and
has an arrow pointing down at it.

Adding Coolant

If more coolant is needed, add the proper DEX-COOL
coolant mixture at the coolant recovery tank, but be
careful not to spill it.
If the coolant recovery tank is completely empty, add
coolant to the radiator. See Engine Overheating on
page 5-30.
CAUTION:
{
Turning the radiator pressure cap when the
engine and radiator are hot can allow steam
and scalding liquids to blow out and burn you
badly. With the coolant recovery tank, you will
almost never have to add coolant at the
radiator. Never turn the radiator pressure
cap — even a little — when the engine and
radiator are hot.
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.
®
Occasionally check the coolant level in the radiator.
For information on how to add coolant to the radiator,
see Cooling System on page 5-32.

Radiator Pressure Cap

Notice: If the pressure cap is not tightly installed,
coolant loss and possible engine damage may
occur. Be sure the cap is properly and tightly
secured.
The radiator pressure cap is located in the front of the
engine compartment on the passenger's side of the
vehicle. See Engine Compartment Overview on
page 5-12 for more information on location.
