Gate Valves

[Curt Sprenger]

Shane, Thanks.
Yup, found the 5th one. Looking at the Diagram and checking at the Detorit, two valves are beside and just forward of the 8V92 water pump. Looks like they supply/return the dash heater coolant, Auxillary Pump in the supply side.  Two of the remaining three are marked Supply/Return. The 5th has no marking. It might be to shut off the coolant flow if working on the water heater.  Sound good???


The reason I'm investigating is Betty would like the dash heat off as it does get very warm during a hot day, with the front vents open. I'm wondering if the dash area Spoolan Valve needs attention. Does one access it from out front of the coach or remove the dash register forward of the step well cover?

Curt- Mine has a 5th valve up high near the gas strut on the left side of the back of the coach. I think that it worked in conjunction with the one behind the bumper that's hidden from view.
