Buick 2004 Automobile User Manual


 
If you have to add coolant more than four times a year,
have your dealer check your cooling system.
Notice: If you use the proper coolant, you do not
have to add extra inhibitors or additives which claim
to improve the system. These can be harmful.
Checking Coolant
The engine coolant
recovery tank is 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.
The vehicle must be on a level surface. When
your engine is cold, the coolant level should be at
FULL COLD, or a little higher.
Adding Coolant
If you need more coolant, add the proper DEX-COOL
®
coolant mixture at the coolant recovery tank.
{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.
