levenezia123 Posted May 6, 2012 Report Share Posted May 6, 2012 Im the guy who purchase a beautiful 99 black STS in Denver that had a horrible knock due to the previous owner not caring the car. Well, get this. I found a beautiful actually brand new (2,100) miles on a "9" Northstar. Bought the beauty from a the service guy at Don Massey Cadillac, got it for only 1,100.00. It was still in the crate. Had it hauled down to my mechanic a GM mechanic for installation. The engine is a 2001 and asked my friend and service manager at Rickenbaugh Cadillac if 2001 "9" would fit in a 99. He called me back and said it would. Great. I get a call from my mechanic and he informs me that the engine is good and all, but its for a 2001 DTS and he cannot put it in. He said it matches exactly except an area behind the oil pan. The old engine is out, the new isnt installed and I suppose I'll have to sell the 2,100 mile engine and TRY and find a northstar that will fit. ARGH! Does anyone have an idea that would help me with my problem?? Signed, Yikes. Link to comment Share on other sites More sharing options...

JimD Posted August 23, 2012 Report Share Posted August 23, 2012 The mechanical fit it the least of your problems. Due to the extensive engine redesign for 2000+ models, your chassis wiring harness is not designed to match the wiring needs of a 2000+ engine. The short list includes: Totally different ignition coil location, type, and connector configuration. Because the 2000+ engine includes a redesigned crankshaft reluctor wheel, there are redesigned crankshaft position sensors with different connector configuration. And the killer is - 2000+ engines used different PCM parameters AND different connectors. Jim Drive your car. Use your cell phone. CHOOSE ONE !

Frank T Posted August 24, 2012 Report Share Posted August 24, 2012 Yes, bummer, Jim D is 100% correct, a 2000+ engine will not work in a 99 Caddy. You will need to find a 96-99 engine or have yours rebuilt. Link to comment Share on other sites More sharing options...
