chassis heater problem

[sfedeli3]

Robert,

It took me two years to figure out that one of the gate valves was not
opening- even though the handle was turning. My guess is that the gate
valve controlling flow to or from the front loop is closed-
permanently. I know I hated to do it, but eventually you should check
to make sure that the threads are not stripped in the gate on the
valves. Most of the innards can be removed without pulling the hoses
off. You just have to hold the body firmly with a large wrench while
unscrewing the valve shaft and gate assembly.
