The Auxiliary Pump switch on the dash pushes more coolant forward for dash heat.
Feel free to correct me if I'm not understanding this correctly.
Question: Where is that pump located?
Thanks
Frank
Aux pump fills the air bag tank for liftoff from your parking spot .. as I understand it. Quietly fill the tank and lift coach to ride height so you don't have to wait to build pressure while running the Diesel engine .. stealth mode!!
Autocorrect wow!!
Maybe a different Aux pump. My year has a button but is for the air tanks
On my coach the pump is located in the engine compartment. Lower left at rear of engine. Should have 5/8" or 3/4" hose going in & out. I can get a picture tomorrow if you need it.
see ya

Thanks Ken, I'll slide under the left side and have a look.
Tried turing on the pump and listening for it without any joy, we plan on doing some winter travel and the extra heat would be nice.
I'll PM ya with any further questions.
