COOLING SYSTEM BLEEDING
CAUTION: Avoid spilling coolant mixture on engine parts. Coolant may
cause undue corrosion. If coolant is spilled during
procedure, rinse area with clean water.
(1.3L, 1.8L, 1.9L, 2.2L, 2.4L, 3.0L, 3.1L, 3.4L & 3.8L)
1) Fill radiator to base of radiator filler neck. Fill
coolant reservoir to FULL mark on reservoir. On 2.4L models, open
coolant air bleed valve until a continuous stream of coolant flows
from valve. Install reservoir hose to reservoir cap. Operate engine
until coolant reaches operating temperature. Operating temperature is
reached when, hoses feel warm and when coolant flows through radiator.
2) Add coolant to radiator until coolant level reaches
radiator filler neck. Install radiator cap.
(3.5L, 4.0L & 4.6L)
1) Refill cooling system. Start engine. Place heater and A/C
control in any A/C mode except Max and temperature at highest setting.
Allow engine to continue idling until lower radiator to water pump
hose is hot. Turn engine off.
2) Allow engine to cool. Recheck fluid level. Add as
necessary.
(5.7L - Camaro & Firebird)
1) Refill cooling system to half capacity with 100 percent
concentration of coolant. Refill remaining system capacity with water,
until fluid reaches bottom of filler neck.
2) Start engine. With pressure cap removed, idle engine until
normal operating temperature is reached. Close air bleed screw when
coolant is visible dripping from bleed screw. With engine still
idling, add coolant to radiator until coolant level reaches bottom of
fill neck. Install pressure cap.
(5.7L - Corvette)
1) Refill cooling system to half capacity with 100 percent
concentration of coolant. Refill remaining system capacity with water,
until fluid reaches bottom of filler neck.
2) Start engine and idle for one minute. Install surge tank
cap. Raise RPM level to 3000 in 30 second intervals until normal
operating temperature is reached. Turn off engine. Remove surge tank
cap.
3) Start engine. Idle for one minute. Fill surge tank .5"
(12.7 mm) above COLD FULL mark. Install surge tank cap. Raise RPM
level to 3000 in 30 second intervals until normal operating
temperature is reached. Turn off engine. Remove surge tank cap. Refill
coolant as necessary, .5" (12.7 mm) above COLD FULL mark.
