[DeTomaso] Robertshaw thermostat is BACK!

[Mike Drew]

Bill,

The 330-180 thermostat is a WINDSOR thermostat, not Cleveland. 

If you are correct in stating that this is what you are using, that is the simple source of your problem. You manufactured the problem out of thin air by installing thenwrong thermostat. Shrinking the bypass hole may have accidentally improved your situation, but I wouldn’t necessarily call it ‘fixed’. 

It’s ‘fixed’ when you install a 351C thermostat and 351C bypass plate. 

But, having said that, one of the military correlations to Murphy’s law states, “If a plan is stupid, but it works, it isn’t stupid!” :)

FINALLY, we found the problem was the bypass plate had too large a hole and the RS did not block the bypass flow when it should have. I got a new plate with a smaller hole and all my cooling issues went away!  It took me 15 years to solve it...... Bill
