Re: head gasket
2002 Alero GL2 (3.4L) - 38K miles. The most common problem is the lower intake manifold and throttle body gaskets not the head gaskets. However, failure to correct a bad LIM gasket will probably result in blowing a head gasket. We had our LIM gaskets changed out at 30K miles by the Olds dealer under warranty. We had a slight coolant leak at the lower intake manifold gasket.
I recently put on new polished and ported UIM and LIM and a 62mm RSM Racing throttle body. The gaskets put in by the dealer looked good with no visible signs of Dexcool damage. The Dexcool drained out looked good with no visible contamination. Stuff actually looked pretty good so we stayed with it. However, Dexcool after about 5 years doesn't look too good and I would use something like Prestone Extended Life (yellow bottle) which is Dexcool compatible.
We still have the original brake pads and rotors. Still have the original hub/bearings on all four wheels.
Good luck with your Alero.
