I'm looking for an excellent Duramax repair shop in the greater LA area.
My '06 LBZ is overheating when I pull my 5th wheel trailer up a steep grade. At all other times every thing is fine. I have replaced the (2) thermostats, the coolant tank cap
and have bled the system. It's looking like head gasket time!
If Kennedy Diesel was closer, I would be there in a heartbeat.
Thanks
