no gumpy i think i mite have some issues with the radiators iam also changing temp sensor when it shuts down no dash lites and gauge is not over 200 , going to drain the system and flush it
My point is that the symptoms indicate possible safety shutdown, of which temp-stats are one part. They can short out internally and cause the exact symptoms, even though the bus
is not over 200*F. Also, tell-tale lights may or may not be working properly, also (burned out bulb, wiring issues, etc). If you have history with the bus, you should know if
your lights are functionally accurate.
Easy way to test if the problem is safety system related is to remove the wires, one at a time from the temp-stats, low oil switch and low water sensor (if you have one).
If the bus stays running, that's the culprit.
