3800 Series 3 SC to a 3800 Series 2 SC

Asked by Feb 01, 2017 at 06:05 AM about the 2004 Pontiac Grand Prix GTP

Question type: Maintenance & Repair

My car (1999 Buick Pk Ave Ultra) was hit parked in
the driveway. Real f-ed up deal. Anyways the motor
(3800 Series 2 SC) is still good. I'm wondering if it's
possible for me to put my motor into a 2004
Pontiac Grand Prix with a blown 3800 Series 3 SC?

It should work, you may have to change the manifolds to are the pipes work and some of the sensors may have different connections but you should be able too just transfer them, did this on my Dad's Pontiac Bonnieville. A word to the wise, check the oil pumps pickup tube, the engine I got was also in a crash and it had a bent tube that was fractured and would leak air so the oil pressure was not stable. Didn't find it until the engine was running, had too tear it back down to replace the pickup.

Thank you for your response. This will be really helpful. I've been doing research on it and could only find 3800 Series 2 to a Series 3. Basically the same procedure but, slightly different. Thank you for the advice though.
