LLY Duramax FAQ
What is different about the LLY versus the LB7?
The LLY added a variable geometry turbo and EGR for faster spool and lower emissions.
Are LLY trucks known for overheating?
Some early LLY trucks ran hotter under load. Upgraded cooling parts are a common fix for trucks that tow heavy.
