Remember that the once the thermostat is open it is no longer part of the
cooling system other than the sleeve that closes off the bypass. The job ot
the thermostat is to get the engine up to operating temperature as soon as
possible. So it stops the coolant from circulating through the radiator.
Then when the water temperature is high enough it starts to open, until it
is fully opened at what ever the set temperature is.
The cooling from that point on is the job of the radiator and the fan. So if
you are running hot while driving the problem is not the thermostat as long
as you have the correct thermostat installed.
So always check these things when you are looking for an overheating
problem.
1. the gauge is it correct
2. radiator is it a old core. If it is have it REPLACED not cleaned.
3. ignition timing and cam timing
4. carb mixture lean
5. faulty radiator cap causing the loss of water
6. air is flowing through the radiator and not around. all air ducts
installed.
