"I went to change the thermost
"I went to change the thermostats on my 318's, and bought the correct 160's from Sierra, which look like standard automotive-style units. When I removed the thermostat housings, I was confronted with a "Vernatherm Valve #VD-1114628" manufactured by the Controls Division of American Standard. Unlike the standard thermostat, which entirely closes the system, these units have a vertical sleeve valve that fits into a machined brass cylinder in the thermostat housing. At the 'cool' position, flow to the main cooling system is cut off, with the coolant directed entirely to a bypass back to the pump. In the 'hot' position, the sleeve valve rises to direct the bulk of the flow to the cooling system, while still allowing some flow back to the bypass.
Because of the constant flow to the bypass, I am reluctant to replace these with the standard thermostats, however, one of these units is not working (fortunately it's stuck in the 'hot' poition, so I can continue to use the motor), so I need to replace at least that one. Where can I get replacements for these?"
