I have a 2001 Chevy
Monte Carlo with the 3.4 and it overheated.
From my knowledge it has to do with the intake
gaskets going bad. Then it
involves in the head gaskets going
bad.
I
have to now replace the motor at my cost of
$900 with 64k on this motor.
My original has 135,000
miles on it. I
hope this helps.
