heat while driving

[Wayne Kotila]

Does anyone know where the gate valves are on a 1996 PT42 with a 60 series?

Jana,

I needed to do some more investigation into the heating so did so the last day. Here is what I find. Hopefully this helps.

Gate Valve Operation - 1987 PT38 Your coach is most likely the same.

Five Gate Valves are located at the rear of the coach.

Two Valves are located on the street side at or just forward at the 8V92 water pump. They control the coolant flow to Dash Heat. In the open position they allow heated coolant to flow to the dash heater.

Two more valves…one is located forward of and below the top of the rear bumper inside the frame rail. The other one is located curb side of the 8V92 and the Thermostat housing. They control the coolant flow to the chassis heaters, perhaps four heaters depending on year and length.

The 5^th valve… is located curb side about shoulder height just inside the engine room door. It seems to be for isolating the water heater in the event of a blowout in the heat exchanger or if you are working on the heater.

Keep us post as we learn as others.

Thanks for all the suggestions -- we found two valves in the back -- will continue to try different combs.

Front heat is a cavalcade of events. You have gate valves on the engine that need to be open. There are magnetic valves that have to work to let hot water flow. There are 4 or more fuses that need to be good and a dash switch. Then it helps if the booster pump works. then once it all works, it won't shut off and cooks you in the summer time. Oh did I mention you might have a winter/summer switch that may be wired wrong and open the wrong valve and run the wrong pump.

It is cooooollllldddd up here in the north. Can anyone give us some ideas how to get dash heat while going down the road? We have the right vent and left vent closed, the front heat under the camera is all the way to heat -- but the right and left fan switches only blow cold air. Is there another button or switch we need to turn on? Thanks so much. Jana (with ice cube feet) 89pt40wb The Bird House is on the road!
