2021 GMC 2500 Duramax coolant leak how hard is this hose to change? : r
Thinking about purchasing a 23 or 24 gmc sierra with the 3.0 duramax
I drive about 10 miles each way to work, mixed freeway and city
Reading about several issues with this motor, oil leaks, long starts / no starts, def issues, etc I really like this motor and. I have a 2023 gmc sierra hd3500 6.6 duramax March of 2025 the valve body failed after 23,000 miles, which around 6,000 miles was hauling 3,000lbs, no more
The failure happened when the transmission had an extremely hard shift at 55 mph and then went into 5 gear limp mode Computer through code p0700 and p0747. I have a 2022 3500 dually duramax now and haven't had any problems so far and was wondering if there is any advantage to buying a new truck Thanks in advance for any pointers
How are the lb7 cylinders numbered, 1234 drivers side, or alternating like a gas small block?
