[Healeys] JB8 Stuck Heater Valve

[Earl Kagna]

Mike:  In case you have not already solved the problem - a little trick courtesy of friend Bill Bolton in Oregon many years ago:

Try tapping the back end of the valve with a hammer - lightly at first.  You are trying to unseat the valve itself from the valve body by jarring the inner part to break the corrosion on the seat – it’s a simple tapered fit in the body.  This will momentarily slightly compress the spring that holds the bits together.  This has always worked for me.  Just about anything else one can try will likely break the handle off, or damage the assembly in some other way.

This little fix also works for the block coolant drain valve, and the (stock) radiator drain valve.

I have read in the archives about all the handles broken off the heater valve (controls coolant flow to the cockpit heater).  

My handle is not yet broken off.  I can't get the valve closed with reasonable force.  Any hints or suggestions?

Thanks, Mike
