Chevrolet 2007 IMPALA Automobile User Manual


 
When the engine is cold, the coolant level should
be at or above the cold fill line on the coolant
recovery tank. To check the coolant level, look
for the cold fill line on the side of the coolant
recovery tank that faces the engine. If the level is
not correct, there may be a leak at the pressure
cap or in the radiator hoses, heater hoses,
radiator, water pump, or somewhere else in the
cooling system.
{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 fans are
running. If the engine is overheating, the fans
should be running. If the fans are not running, your
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 329 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 your warranty. Always use
DEX-COOL
®
(silicate-free) coolant in your
vehicle.
