2006 Chevrolet HHR Repair Question
Chevrolet HHR Engine Problem
Technically speaking you should be able to. Swap the parts over for the oil cooler from the old engine to the new one. If the new engine didn't come with an oil cooler, its ok not to hook it up. I would try to make it work especially if it is a force inducted (turbo/supercharger) model. If not, it should be ok.
