Question:
I just changed the t-stat and still overheated i took it to a shop and was told it was a blown intake manifold gasket.I,m going to change this myself but would like to know what kind of precautions i should take to prevent this from happening again and should i change the head gasket too because i have read that this engine is prone to overheating. 2002 Chevy Malibu 3100 or 3400 V6. Repairs this problem = i just changed the themostat.

Answer:
Thank you for the generous tip/donation. See picture below. There is no special valve adjustments on this motor as was the case with the chevy small block. Rocker arms are just torqued to specs. The most important thing is that the push rods are installed correctly. They are different lengths. Exhaust rods are longer and the Intake rods are shoter. GM recommends installing new lower intake bolts, and have updated the torque specifications on rocker arms and lower intake bolts. The intake and exhaust rocker / push rod location is in the picture below...

Question:2002 Chevy malibu 3100 V6. Repairs done prior = i just changed the engine. I changed the t-stat and the intake manifold gaskets. I did thi work above but the car is still overheating and losing water. I'm guessing it has to be a head gasket. I'm going to go ahead and change both of them with a Felpro severe duty gasket and hope and pray this solves the problem. Is there any advice you can give or something i should pay close attention to also could i get the torque specs in ft. Lbs for the head bolts.
