Question about 2004 Chevrolet Impala
Posted by Anonymous on
I going to assume you have the 3.4L or 3.8 L motor
these motors are notorious for trapping air in coolant system
which sounds like what your problem is
not a problem tho they have bleeder screw built into them
there should be one or two bleeders (depending on model year and motor size)
i think yours should have two
one should be on top of thermostat housing
other one right above water pump on bypass tube
open one bleeder at time with motor running until u see just water and no air
repeat with other bleeder
continue to work back and forth between the two bleeders until thermostat opens
then work back and forth a couple times after thermostat opens
keep checking radiator add coolant as needed
