GMC Troubleshooting Questions? Ask a Mechanic for Answers
Hi. You do have to replace that engine with another 3.6L engine. The reason is the computer and controls are designed to work with that engine. Getting a different motor would be a completely custom job with different computers and wiring harness. Probably not worth it.
Yes. Unfortunately it has to be the exact same engine. That is because all the electronics on the vehicle are specific for the the engine installed.
