Re: [Healeys] thermostat discussion

The new replacement thermostat probably has a lower operating 
temperature. It is not particularly a good thing that the engine is 
running cooler. The higher the operating temperature the higher the 
efficiency of the engine. Also less carbon build up in the cilinder 
head. Compare the stamped temperature figures on both thermostats.
The idea is that the temperature remains constant (more or less) at any 
load. If that is not so there is trouble in the cooling system, usually 
scale in the engine and or radiator on USA cars as often tap water has 
been used in the past instead of proper coolant.
