Radiator steams after short drive.

New radiators are expensive but really nice to have. Pick the most heavy duty one that fits your car.

Be careful about finding the cheapest radiator you can find. The cheap ones often do not fit well. The Model A vendors (Snyder’s, Bratton’s, etc.) sell radiators that actually fit.

Good afternoon...When it come to these sorts of parts, there is an old saying 'Cheep people usually pay twice!' Once for the cheep part and then again for the good part after the cheep one fails. Model A's are simple but lots of work...no fun doing the same job for the second time...it can make you say bad words! Ernie in Arizona
 
Thanks for the info. Today i put in a gallon of Prestone. 1 bottle of Rislone Hyper cool super coolant and a little over a gallon of water. Took it for a drive. Shut off the engine. Temperature at the top of the radiator is about the same but now I'm not seeing steam coming out of the overflow tube! Just some coolant. But I think it's still too hot.
I am waiting on a set of feeler gauge from Amazon so I can check the points. When I sold my '69 Mustang years ago I threw in the feeler gauge because I was sure I would never need another!
My mechanic neighbor says it's not an original radiator and it has been fixed at least once before. I'm thinking I will probably need a new radiator. Any recommendations? I want to be able to drive the car at least 50 miles to car shows. Do i need to get a pressurized radiator? If i do I assume I would also have to get a leakless water pump?
 
And yes, I definitely will be buying from one of the Model A suppliers like Synders. How are Brassworks radiators? Pretty pricy.

From experience, getting a good one is NOT easy. A few years ago, I bought a Brassworks radiator and recently had to have it repaired. The repair cost me nearly as much as the radiator did, the workmanship was so bad. Even I could see that it was rubbish. From that experience, I have resolved that if I need another radiator, I will have the same workshop recore my old one. My advice would be to find yourself a decent radiator shop and have that done. Other members of this forum might have clues on such a place.
 
You are using distilled water right?
50/50 on the anti freeze right?
Pure anti freeze will make it over heat.

Leakless pumps work great. Problem is they are
in short supply last time I checked. 200 degrees is
too hot. This time of year should be 150-160 tops.
I have a temp gauge in mine so I know.
 
Yes. I checked the mixture with prestone tester. Its good to to 25-. Looks like I must have about 55% water 45% prestone. Ill drain some out and add more prestone till its good down to about 40-. I definately want a temp gauge. Ill need the water outlet with a fitting for that?

This should work.

However, this is what I use. It lets you add a thermostat close to the head, rather than in the water pipe. I run a 160 degree thermostat, and it usually never gets higher than 170 degrees, even on a hill.
