Shutting off the heat

[pattypape]

Robert,

On the 87FC;
There are three Sporlan valves to control the chassis heat, Front heat has one
about the air filter. The rear chassis heat controlled by the Winter/Summer heat
switch, One on the rear driver side high above the bumper close to the floor,
another above the driver side front wheel, high near the floor hidden in a
bundle of wires and tubing. The Front valve will leak coolant , either repair
it fast or drain the coolant. No rewiring necessary order three kits & rebuild
the valves with the repair kits available from:

The rear sporlan valves in addition to controlling the heat, control the coolant
flow and the return lines so there is always hot coolant flow to and from the
Hot Water Tank.

know that there are two wires going to the valve. One red the other white. Do
you know if the white wire goes to ground? Does the red go to the front heat
switch?
