engine swap

[niles4tomas]

Hi. I'm new to this so I might need a little help.
We just got a '99 venture that needs a new engine.
Can we use a 3.4L from an '01 grand am instead??

Welcome to AF. Any salvage year can give that info from their interchange books, this avoids any misinfo.

You most likely can use that motor. However, you have to check and recheck the electrical hookups. The vehicles main harness has all the plug-ins for the components and the engine component hookups have to match.

You will probably have to swap out components from the old motor to the new one.

Example, I put a 99 motor in a 97. the 99 had a slightly different harness on the fuel rail injectors and temp sensor wire. I had to use the 97 parts on the new motor. This is one of 3-4 things that were different.
