Thermostats

[31chevy]

There has been a very long discussion on thermostats & I have read most of the threads & I am still confused (which is normal for me) I have a 21 stud 1934 with water pumps in the head (Skip's) I don't think that Henry put thermostats in that engine (correct me if I'm wrong) The only place that I can see to put the thermostats is in the hose's. Please advise me as where to install them (Close to radiator or close to heads) & which thermostat to use & how to install them. Any & all help will be appreciated.
Thank you.
Gary.

Thermostats for 32-36 are Ford Part Number 40-8575-A 140-145°. The thermostat goes in the hose.

Here's one for sale on ebay. http://www.ebay.com/itm/1932-1933-1...Parts_Accessories&hash=item1c35030adb&vxp=mtr

Gary-

I have them on my '35 and '36. As mentioned, they go in the upper radiator hoses and are kept in place with a radiator hose clamp. Picture enclosed is of my '35. The extra hose below the clamp is for my heater.

Hope this helps.

Tom, Where did you get your thermostats? I'm not finding them at the usual sources.

Henry-

Check your PM.

Those look like they would be a major flow restriction.

Same request (source for "butterfly" or replacement stats for 21-stud blocks).

My vehicle currently has no thermostats in it. OK for now, still cleaning the block and radiator out.

Those look like they would be a major flow restriction.

The originals are a butterfly type stat. When they open up there is little restriction.

Newer styles are more restrictive and some guys drill relief holes around the edges.

Maybe so, but look at the size of that spring. Looks like a pretty large restriction to me.
