[BusNit]

Has anyone added a valve to regulate the engine coolant entering the rariton heat exchanger? After a drive, the water is scalding hot. Now that I have the coolant out of the bus I was contemplating adding a couple of shut off valves. Heater is Tee-d off a branch that continues towards the front of the coach. I was going to put the valves next to the water heater in-line with the coolant hoses.
