Are Jeep liberty 3.7 liter engines interchangeable Have a bad 3.7 liter engine in a 2003 Jeep liberty and was wondering if another year engine would work in it?

Answer 1

Yes, you can swap them. Just has to be an engine of the same year or newer for emmissions purposes.

THE ANSWER ABOVE IS WRONG.

UNFORTUNATELY, YOU CAN ONLY SWAP A 2002 - 2003 ENGINE WITH A 2002 - 2003 ENGINE. 2004 (AND NEWER) ENGINES ARE SLIGHTLY DIFFERENT. THESE DIFFERENCES HOWEVER MAKES THE SWAP NEARLY IMPOSSIBLE...HENCE, YOU WILL FIND THAT 2002-2003 LIBERTY ENGINES ARE SUBSTANTIALLY HIGHER IN PRICE THAT THE 2004 AND UP ENGINES.

YOU WILL FIND PLENTY OF EXAMPLE ON THE internet WHERE PEOPLE TRIED THE SWAP UNSUCCESSFULLY.

GOOD LUCK.

'02-'03 engines will interchange with each other only (main difference is the reluctor wheels on the crank and cam).

'04 engines only work in '04 due to having unique computer setup (again the reluctor wheels).

'05-'06 interchange with each other and '07+ will not go in the older ones due to addition of EGR (right head is the same and that is about all that will swap externally).
