Hoping for some expertise. Trying to change her engine. She has the 4 cyl engine and it’s burning oil badly. So I found a 2007 Malibu with a 4 cyl engine. Are they interchangeable. so far I’ve been hearing there are differences and it’s not just a drop in.
thoughts please.
TIA

The engine sensors went from analog to digital in 2007. You would need all the electronics form the donor car, ECU, BCM, wiring harness and more. The head and camshafts are different as well.

Thanks. Now I’m stuck with a 2007 engine. Can I assume that the 2007 4 cyl engine will fit in 2007 up to 2010? I may have a way to save some money and sell it.

Your 4 cylinder is a 2.2 ecotec from Gen 6 Malibu (2004-2007)-Gen 7 debuted in 2008 (2008-2012) & the 4 cylinder had the 2.4

I’m totally confused. The motor I got was from. 2007 but the mechanics said it won’t fit for a number of reasons In the 2006. They said VVT And that there was a number of differences and unless a bunch of changes were made it won’t bolt up Electrical etc. I’m now guessing that it may be a late 2007 VVT engine. Bottom line I can sell it knowing it can be used up to 2010. Thanks

GM used the 2.2 in the Saturn Ion and Chevy Cobalt as well-different components no doubt but discontinued-the 2.4 was in the Gen 7 Malibu-I’m no mechanic however-best to you
