00-02 engine swap question

[a_kraker99]

I am sure this was covered before but I can never find anything using the search function on forums.

I just have 1 quick question. I have been looking for 3.9l v8 engines for a 01 LS and it some places seperate the 00-01 and the 02 in terms of compatability. 00-02 are all generation 1 right? If so then what is the difference in an 02 engine? Would it be compatible?

Yes.. no difference..

So did that 02 engine work for you? Was there any difference?

The main engine harness is a different part number even within gen1 years, wonder why that is.

When my motor was replaced in 2009, the dealer told me the location of a couple of sensors were different, and the routing of the fuel lines was different between 00-01 and 02.

On the 3.9, the fuel lines are in the same place on the engine in all first gens. I got an intake manifold from a 02 and it bolted right up to my 00; everything was in the same place. Idk about sensor locations but if they're moved, that shouldn't make a difference. The main plugs should be in the same spot..

Forgot to mention, mine was a V6.

On the 2002 3.9 there are a couple of lubrication lines coming from the oil pump that point directly onto the lower timing chains providing a stream of oil that the 2001 does not have. I'm assuming the 2000 is the same as the 2001.
