Buick 2004 Automobile User Manual


 
The coolant level should
be at least up to the
FULL COLD mark.
If it isn’t, you may have
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.
CAUTION: (Continued)
CAUTION: (Continued)
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, start the engine again.
The engine cooling fan speed should increase when idle
speed is doubled by pushing the accelerator pedal down.
If it doesn’t, your vehicle needs service. Turn off the
engine.
Notice: Engine damage from running your engine
without coolant is not covered by your warranty.
Notice: Using coolant other than DEX-COOL
®
may
cause premature engine, heater core or radiator
corrosion. In addition, the engine coolant may
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.
