check engine light BUICK PARK AVENUE 2005 User Guide

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. When your engine is warm, the
level should be up to FULL HOT or a little higher.
Adding Coolant
If you need more coolant, add the proper DEX-COOL
coolant mixtureat the coolant recovery tank,but
be careful not to spill it.
{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,
seeCooling System on page 5-28.
Radiator Pressure Cap
Notice:The radiator cap on your vehicle is a
pressure-type cap and must be tightly installed to
prevent coolant loss and possible engine damage
from overheating. Be sure the arrows on the cap line
up with the overow tube on the radiator ller neck.
SeeEngine Compartment Overview on page 5-12for
more information on location.
Engine Overheating
You will nd a warning light about a hot engine as well
as an engine coolant temperature gage on your
vehicle’s instrument panel cluster.
