1988 FC water coach heater question

[krminyl@...]

Bruce,

I can't offer much help, but I'm sure other FC owners will chime in. I have
a 86 PT, and there are plumbing-style gate valves in my engine compartment
that can be manually cranked closed (similar to turning off the water to your
home sprinkler system). This prohibits coolant/antifreeze from circulating
to your heaters, and closes the engine coolant system to just the engine
radiator.

I would think the FC's have a similar system. The winter/summer switch on
my PT opens or closes a Sporlan valve in my engine compartment which allows
the coolant to flow into the chassis heater system, and the "Aux Pump" switch
is a booster flow pump that helps push all that coolant through 70' of coolant
hoses and heater cores.

Look for that Sporlan valve (in-line brass device with a electromagnetic
solenoid on top with two wires)...it can be rebuilt for about $15, or replaced
for about $40. Since it's summer, if your BB has those gate valves, maybe you
can just close off the chassis heaters from the BB's engine cooling system,
and fix the Sporlan valve when it's convenient.

How about some FC's owners...any suggestions or advice?

Best of luck...I can only imagine what it's like competing against chassis
heaters in 100 degree weather with the A/C.
