heat while driving

[Jana Ewart]

We are finally on the road "full-time" as of this morning.  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.

Here is some general trouble shooting information. PT owners may know some
tricks specific to your rig:

The fans blow cold because the heater core is cold. Are there other chassis
heaters (not propane furnaces) around the bus that blow warm? If so, then your
hot water circulation is working.

There is probably a Sporlan valve controlling hot water flow to the front heater
cores. The valve is controlled by a a 12 volt circuit. That circuit inlcudes
the 12 volt source power (fuse? breaker?) and one or more switches. One switch
is probably a manual control somewhere on the dash. There may also be a
thermostat (temperature controlled switch) somewhere in the dash.

Other possibilities: 1. The front heat Sporlan valve gets power, but the valve
is plugged or broken. 2. There is a summer/winter valve (manual or Sporlan)
that is shut off. 3. The front heater core is plugged.

Your 'Bird is a couple years newer than our '87 so may be some differences.

Is there a Summer/Winter switch in the upper dash above the driver? Set it to Winter.

Is the Heat switch in the lower dash set to Heat? Our Heat switch location is just below the two Fan switches.


At the rear of the coach engine we have 4 gate valves. These need to be in the open position. They are located just forward of the rear bumper, about shoulder height on the street side next to the engine thermostat housing, a little lower on the curb side by the exhaust tube, can't remember the location for the forth valve. Opening up those valve will let the engine coolant flow throughout the coach and you should have heat.


There is is a heater under the couch that works off the engine coolant. Next to the vent are two switches, one is ON/OFF, the other is the fans speed. Set to On and High/Low. Set the wall Thermostat to 70 degrees and be sure it's in the ON position. The thermostat in our coach is on the wall above the couch reward end.


There are more heaters, probable at least a dozen in your coach. Makes for a long story.

You can also run the generator and turn on the electric toe heaters that are just above floor level.

Hope this helps.


Good luck.

Check the dash for a switch labelled 'front heat'. That switch will cycle 12V
power to the 'Sporlan Valve' which in turn will allow engine coolant to flow
through the front heater. If you have good hearing, you will be able to hear
the Sporlan cycling on and off as the front heat switch is repositioned. You
should also feel the Sporlan internal mechanism move when the front heat switch
is cycled. A helper will make it easier to check for sounds and Sporan
movement.

Sporlan valves are easily cleaned if flow is not achieved.

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.

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

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.

If you do a search on "gate valves" here you will find my saga when my heat went
away. In that thread, a couple of people talked about the shaft corroding and
the gate dropping closed from gravity, and eventually that is what I found had
happened with one of mine.

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

Look for round 2+" that rotate either way. Could be ball vales instead of gate vales...look for handles vs. round handles. I'm not up to speed on the 60 series. But, my guess, BB plumbed the 60's basically the same as the 8V92.  Someone wil chime in with more info.
