Gate Valves - Curt Sprenger - 10-11-2009 09:55

Anyone know which of the four coolant gate valves work with the
hot water heater vs. the chassis heaters? This is for our '87 8V92.

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.

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?

On mine, that forward valve (which happens to be a Bosch on this coach rather
than Sporlan) is only accessible from below.

Hi Curt,

Glad you found it. I'd agree- 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. My front dash heat behaves the same way- even with the dash switch off,
it still gets warm. I have to turn off the two valves on the top and bottom of
the engine water pump to keep the queen happy in summer.
