Thermostat

[Gene F]

Can I ask a question. Who cares if it ends up at the top end of the hose, up against the radiator neck. I mean why do we care? It still will slow down the water.

It doesn't open until the hot water gets to it. Close to the engine it will open sooner. The engine will be at a higher temp before the hot water migrates to the top of the hose since water won't be flowing with it closed.
The small holes in the thermostat is to let air out of the system when you refill it.

You need a plug in the side your distributor, helps keep dirt and moisture out

Why do you want to slow down the water? It's not the old BS about the water not spending enough time in the radiator to cool down is it?

Seems to me that with the thermostat at the upper dead end of the radiator hose, 18 or so inches from where the heat is generated, you would run the risk of overheating before the heat transferred enough to open the thermostat. I like the thermostat lower, on the head, for that reason.

I guess I have the same question as Synchro. Maybe for our Model A friends in Northern states it would make sense to have a thermostat. I live in Texas - today it is 100 degrees F here. I don't see the need of using a thermostat in our climate. We have NO problem getting up to temperature quickly! I have a REXACO temp gauge and going down the road on a hot day like today the gauge is nudging 190 degrees. I cant imagine anything blocking a healthy flow of water under these conditions. Our winters aren't that brutal, so even then I don't see the need for one. Am I missing something here?
