2004 PONTIAC GRAND PRIX radiator cap

5. Fill the radiator with the proper DEX-COOLž
coolant mixture, up to the base of the ®ller
neck. SeeEngine Coolant on page 5-26for more
information about the proper coolant mixture.
If you see a stream of coolant coming from
an air bleed valve, close the valve. Otherwise,
close the valve after the radiator is ®lled.
6. Rinse or wipe any spilled coolant from the engine
and the compartment.7. Replace the 3800 Series III V6 engine cover shield.
7.1. Remove the oil ®ll tube, with cap attached,
from the valve cover.
7.2. Insert the catch tab on the cover shield
under the bracket on the engine.
7.3. Place the hole in the cover shield over the
hole in the valve cover. Install oil ®ll tube and
cap by twisting clockwise.
8. Then ®ll the coolant
recovery tank to the
COLD mark.
9. Put the cap back on the coolant recovery tank,
but leave the radiator pressure cap off.

10. Start the engine and let it run until you can feel the
upper radiator hose getting hot. Watch out for the
engine cooling fans.
11. By this time, the coolant level inside the radiator
®ller neck may be lower. If the level is lower, add
more of the proper DEX-COOL
žcoolant mixture
through the ®ller neck until the level reaches
the base of the ®ller neck.12. Then replace the radiator pressure cap. At any time
during this procedure if coolant begins to ¯ow out of
the ®ller neck, reinstall the pressure cap. Be sure
the arrow on the pressure cap lines up like this.
13. Check the coolant in the recovery tank. The level in
the coolant recovery tank should be at the HOT
mark when the engine is hot or at the COLD mark
when the engine is cold.

Engine Cooling System Inspection
Inspect the hoses and have them replaced if they
are cracked, swollen or deteriorated. Inspect all pipes,
®ttings and clamps; replace as needed. Clean the
outside of the radiator and air conditioning condenser.
To help ensure proper operation, a pressure test of
the cooling system and pressure cap is recommended
at least once a year.
Throttle System Inspection
Inspect the throttle pedal system for interference or
binding, and for damaged or missing parts. Replace
parts as needed. Replace any components that
have high effort or excessive wear.
Brake System Inspection
Inspect the complete system. Inspect brake lines and
hoses for proper hook-up, binding, leaks, cracks,
cha®ng, etc. Inspect disc brake pads for wear and rotors
for surface condition. Inspect other brake parts,
including calipers, parking brake, etc. Check parking
brake adjustment. You may need to have your brakes
inspected more often if your driving habits or
conditions result in frequent braking.
