In Reply to: exhaust heat valve, what goes on the shaft outside? posted by scott 56 [24.130.235.145] on Friday, June 27, 2014 at 15:14:15 :
I think the thermostatic springs were always on the outside of the exhaust manifold.
Yours may have also have had a balance weight that pivoted on the shaft and to which the spring attached.
