Pontiac 2008 grand prix Automobile User Manual


 
{CAUTION:
Heater and radiator hoses, and other engine
parts, can be very hot. Do not touch them. If you
do, you can be burned.
Do not run the engine if there is a leak. If you
run the engine, it could lose all coolant. That
could cause an engine fire, and you could be
burned. Get any leak fixed before you drive the
vehicle.
If there seems to be no leak, with the engine on, check
to see if the electric engine cooling fan(s) are running.
If the engine is overheating, the fan(s) should be
running. If the fan(s) are not running, the vehicle
needs service.
Notice: Engine damage from running your engine
without coolant is not covered by your warranty. See
Overheated Engine Protection Operating Mode on
page 5-29 for information on driving to a safe place
in an emergency.
Notice: Using coolant other than DEX-COOL
®
may
cause premature engine, heater core, or radiator
corrosion. In addition, the engine coolant could
require changing sooner, at 30,000 miles (50 000 km)
or 24 months, whichever occurs first. Any repairs
would not be covered by the warranty. Always use
DEX-COOL
®
(silicate-free) coolant in the vehicle.
How to Add Coolant to the Coolant
Recovery Tank
{CAUTION:
Adding only plain water to the cooling system
can be dangerous. Plain water, or some other
liquid such as alcohol, can boil before the
proper coolant mixture will. The vehicle’s
coolant warning system is set for the proper
coolant mixture. With plain water or the wrong
mixture, the engine could get too hot but you
would not get the overheat warning. The
engine could catch fire and you or others
could be burned. Use a 50/50 mixture of clean,
drinkable water and DEX-COOL
®
coolant.
If you have not found a problem yet, but the coolant
level is not at the COLD FILL line, add a 50/50 mixture
of clean, drinkable water and DEX-COOL
®
engine
coolant at the coolant recovery tank. See Engine
Coolant on page 5-24 for more information.
