Thermostats

[ajmac]

Alex, that would only apply to Post 1948 Flatheads with the modern style thermostat housing at the front of the heads though, not the earlier type where the unit sits on top of the hot water outlet in the top middle of each head.

Earlier ones are only held in place by the rubber hose pressing into there circumference. The original wartime type with bellows would have had the bellows section sitting down in the water outlet pipe with the valve up at the top sitting on the end of the water outlet. Modern wax type are shorter so have very little hanging down in the pipe. When mine is rebuilt I am fitting post 1948 water pump impellors whch have a much increased flow rate and dosing the water with water weter, I haven't thought much about pressure caps, the post 48 had 4 Psi, but I am not sure about the truck style system fitted to the Loyd.
