Well, i know a guy with a 38 who runs NO FAN & it never overheats. I have taken the 160 Stants out on my 52 Vic & replaced them with Stant 180s. Drilled a 1/16 hole in them and that engine runs @ 180 & 185 on hot days. It ran 190 + with the 160 stats. mike

170 degrees is a little on the cool side;At 180 degrees the motor runs more efficiently. That's the temperature where every (4) cycle automotive engine is supposed to run.

The wshers are not thermostats. They were installed to slow the water flow in the cooling system. Using them has been proven garbage science many times.

Steve Lee, All of our modern cars are designed to run right around 200°. One of them is designed to run at around 210°.

I can tell you what I did more then 10 yrs ago when I built my flathead up. High flow pumps, expensive, 4 row walker radiator, it got hot on my hill. I wasted a lot of antifreeze and water wetter trying things. Tried stock thermostats in the hoses. It got hot. I added a puke tank. I tacked washers to two 5"pcs of pipe that I cut into the upper hoses. It got hot. so I bought 2 modern high flow, big block 185' thermostats at napa, trimmed them and tacked them to the pc of pipe. At first I put them on the bottom, close to the heads, It got hot. So remembering that stock thermostats go in the upper part of the hose, away from pump wash (21 stud, pump in the head) I tacked them to the top of the pipes. That was 10 years ago, it works perfect, warms up quick,(I put a heater in it to blow up grandma's skirt so she'll go with me, you need a thermostat for a heater to work) Dosen't get over the 190' on a hot day. I have rarely added water to it. I better change it. The 50/50 antifreeze and redline water wetter must be shot. But it was the answer to my hot engine. That Napa thermostat # 191. Each one keeps a 427 or some big engine controlled, 2 of them works perfect for a flathead. That pc of pipe could be much shorter if you didn't like it. I think it would work on a later flathead also. Happy Motoring!
