kgc>Hello, I have a 1997 Cadillac STS with the Northstar engine. I have
kgc>a few problems with it and am thinking of replacing the engine. I
kgc>have found a 1995 Cadillac STS that has been in an accident, but the
kgc>engine is good. Would this engine be the exact same as mine and allow
kgc>me to do a straight swap? If not, is there a list somewhere of
kgc>compatible years/models that would be suitable as donors for my car?
kgc>Any help would be greatly appreciated..
The engine is the same; however, the '95 is still OBD-I ('96 and newer are
OBD-II), so you'll have to double check the sensors and their interfaces.
Also, the difference between the STS and SLS engines is only noticeable at
peak RPMs (which you are rarely at during every day driving), so considering
those would double your chances.
