Re: Duramax owner ready to make the switch
The LMM didn't have any issues with overheating.
I thought that was the LLY that was prone to overheating.
I know the LMM is very sensitive to water in fuel. A buddy has a GM performance shop and they have had two LMMs in the past few months needing a new fuel system and injectors.
