cooling system
-
I am a new 50 ford flathead owner. I am having trouble keeping the car running cool,and keeping coollant in the radiator. Using a 4lb radiator cap. there are no thermostats,do i need them,if so what temp should i put in. I cannot find any leaks,except what cones out the overflow tube,and that only seems to happen if i fill the radiator all the way.
The engine runs strong,I have a c4 auto transmission installed.
I have had trouble with engine not starting unless its promed. Rebuilt the fuel pump,but still had trouble getting the engine to start after a long drive. I think an electric pump will solve this problem.
any help or information will be appreciated

Thanks steve. I will get the thermostats tomorrow and give it a try.

FYI
Another suggestion is to not fill the radiator up to the top since water/antifreeze needs room to expand when hot and will usually toss out some water until down an inch or so. Another thought is to buy and install a coolant recovery system. They are cheap and work well... -
Ok,ol racer,that is one i never thought about.

Steve E. I Forgot To Tell You,that My Ford Is Running Cool Now,wrong Thermostats Were In It.

Hello Nightstick,
Just a little more advice on keeping the flattie cool. My coupe is also a 50, and is equipped with Fenton cast iron headers, Offy 9:1 aluminum heads,Offy tri power intake with Holley 94's, and an isky cam and kit and a Joe Hunt ignition.
Keep a 50/50 anti freeze mixture in the system at all times. Most importantly be sure your ignition timing is set to the timing mark or even a little more before top dead center. Flatheads like ignition advance.
I also have a Ron Davis Racing Radiator with a 50/50 mix and a 16 pound cap and I had overheating problems with my timing set to the factory mark on the crank pulley until I moved my timing to about 15 degrees before t. d. c.
Cool! Cool! Cool!
Good Luck
Wendell
