Overheating at start up 08 - 40x Discovery
My 08 Discovery 40x w/ 350HP Cummins is getting hot when i first start out on a journey.
It will do this every time, but only when it starts off from cold. It will go to 215 to 220 and will start to go into shutdown mode, BUT if i stop and shut it off for 3 to 5 minutes and fire it back up, it will be fine all day & night. 100's of miles, doesn't matter, stays at 185 to 195.
Coolant expansion tank is full and there aren't any leaks.
My first though was thermostat, but last time it did it, i opened the side door and the fan appeared to be spinning kind of slow.
Anyone else have this issue?
Also, if its the thermostat, how hard is that to get to?
Thanks in advance
