Can I swap a motor from my 2005 Chrysler Town & country 3.3l
Is the motor from a 2005 Chrysler Town & country
3.3l compatible with a 2005 Dodge caravan
As long as the 05 Dodge Caravan was equipped with the same 3.3L, yes.
If you have the same model year and the same basic platform, the engines would have been manufactured the same. All components, including electrical and position control would be the same. Accessories might differ, but you would be keeping those that came with your van: air conditioning, cruise control, etc. This should be a simple replacement. Replacing an engine with one from a different year or a different platform would entail some modifications or wire harness supplements to work.
