Engine Swap

Whats up everyone,

I have a 2002 Jeep Liberty 3.7 V6 and well my engine finally gave out on me. Now instead of actually rebuilding the engine, I rather just swap in a new engine and get it done.

Here is my question:

- I want to know if the 2005 Dodge Ram 3.7 V6 fits my 2002 KJ?

- I want to know if a 2006-2008 Jeep Commander 3.7 V6 fits my 2002 Jeep Liberty?

- I want to know if a Dodge Durango 3.7 V6 fits my 2002 Jeep Liberty?

If anyone knows if they do or if there is a difference, I would greatly appreciate it. I am planning to use the same transmission on my KJ so I want to just swap in the motor and bolt on MY transmission.

Thanks and look foward to hearing what you guys know.

Dodge Durango 3.7 won't work, used the 42RLE tranny. Ram might be the same....

3.7 was bolted to 45RFE, 42RLE, the 5 speed and the 6 speed

the difference in the 3.7 internals came in 2005 with a different cam, valves etc

which should all operate just fine with your 2002 electronics, if not, it's something that can be fixed
