thermostat

From what I know about thermostats, the correct thermostat depends on the altitude, winter temps, summer temps, and most important, truck usage. When i was removing the heads to get the sheered exhaust bolts, i noticed the truck did not have a thermostat. I guess that explains the lack of heat this winter. What temp thermostat do you recommend? I'm running a stock 360, my elevation is 3000 ft, winter temps are around 20s, and the summer is up to 115. This truck will be used pretty much as sunday driver.

I had a 360 in a 73 that I ran a 160 in when I was in Utah. That’s just what it had in it when I replaced it, I don’t know how to determine what best temp is. There are a lot of smart folks here that will give you all the info you will need. Where in Idaho does it get to 115?

Here Idaho I run 160 temp. I have one in my 70 F100 "302" and 67 mustang "289" and they both work good for me. I also had the same in a 351M

A 180º or 195º would be proper, along with a 50/50 mix of coolant and water. I believe 180º is what came from the factory. Bill will know for sure.

Chad, That is not my recollection, from when they were new.

i run a 205 in the winter which really bakes your butt! and a 175 in the summertime. i have a little assortment of thermostats. at 180 degrees the motor seems to perform the best. and yes i think that is what comes in them stock.

I do not believe altitude and temps have anything to do with it. The tstat controls the temp that your engine runs at and I think 192 is stock. When you get a replacement you get a 195. The 360 in my truck had a 160 in it when I bought it and it didn't run real well. I put in a 195 and it runs great now once it's warmed up.

I also had a 180 in it and just replaced with a 195 from NAPA which is what is called for. I noticed an improvement with the general run of the motor. My understanding is that Fords like to run a little warmer to get the most out of them. I can tell you it runs better after warm up.
