Well since Ollie has his gun trained on my I am a bit shy about answering. I have been right where you are with my car overheating at traffic lights if I got say three reds in sucession. I have been the rad route and fooled around with all that stuff trying to to solve it . then i sat down a few years ago and thought it out. My car Does NOT overheat when moving. It overheated when sitting still. What is different? It was in gear and idling. I knew in fact if I put it in eutral at the lights and kept it running at a bit faster clip I could get buy but that is hardly practicle and get old fast. So i reasoned if I could speed up the pump and thefan I could solve the problem . I set out looking for a smaller pully. I did not like some look to see what wouldnt work and was the same size I looked for one that was smaller. I found it on a Poley 318(313 Can) The cure was immediate. I caculated the fan speed increase from the pulley change. i have forgotten the figure by now but it was significant. (Several hundred RPM) Bills was no differnt and unlike me he had everything in his car yet it stilll got hot in traffic. I told him waht to do and like many others he had a hunf dred reasons why it would work which included the rad guy said and so and so at such and such says. I who am very short on patience (That trait comes with the square head) did not answer. i just went to the vinatage wreckers bught a pulley andtook it to Bills and installed it. That was 4 years ago now. I have driven mine now over 30000 miles. You can not believe or try or po po the idea but what would it hurt to try it. Find a WP pulley that fts that is at least 1/2 inch smaller and install it. What if it works? You dont even have to tell me. Remeber I am not selling parts or motors . I have nothing to gain. I am only trying to help based on 40 years of professional experience as a Mech machinist. I understand the 105 to 115 f is extreme. it is possible that is not easy as here I wouldnt deny that. I dnt now what my core count is but I do know doing the rad did NOT fix it. It was $450 shot for nothing. Perhaps some of you know that feeling. By the way the poster wh mentioned drilling a small hole in the flat part of the stat is also right on. Tis a very good idea and will lower the temp soe as well as eliminate the air lock problems. Anyway. this has n been muy experience for what it is worth. I worked inthe tradee when these cars were common and the rad guy was right, Mopar overheating was not normal back then.

Don, I am sure that under normal conditions you are absolutely correct however here is my story: I found a reproduction fan shroud however it did not fit due the the location of the side straps in relation to the tanks. When it was re-cored the tanks were set too far back. I went looking for a radiator shop to move the straps, here is my story so far: I am in Yuma Arizona where in the summer there are nights when it does not get down to 100 degrees, normal temperature during the summer is 110 to 118 degrees. I could park the car in the summer like some of you guys do during the winter but I still want to drive it. I went to an old guy in a radiator shop in Yuma and told him my 63 SF was over heating - He said old Mopars don't over heat, I must have the wrong thermostat, he looked and found an old unit that looks exactly like the Milodon one that is sold today. I told him I had a high flow thermostat - He said my timing was off. I told him the timing was correct - Finally he went out and looked at the radiator and told me I had the wrong core. I only had 10 fins per inch and asked who did the re-core. I told him it was done in Arkansas where my brother and I built the car - He said the radiator was my problem, it would work in Arkansas but not in Arizona. He also said a shroud would not help but he did relocate the side straps so I could mount the shroud. He was right, it did not help and probably hurt. I would be interested in knowing the fin count on your radiator however I have spent too much time and money and I am ready to be done with the problem. I want to be able to drive through Yuma when it is 115 degrees out and be able to stop at a light. As a final note, I have extremely enjoyed all of your comments, your experience is priceless. I have a file with just your email comments. Dennis C. Don Dulmage wrote:I read all these cooling deals. I have fixed many with a simple pulley change. It gets over ninety here in Canada quite often (was 82 yeasterday)and occasionally we d see 100F. Still car runs fine as do the ones I fixed. I think the tech must still be around on site. it works and costs a lot less that several rads doubleyoked mikawaky pumps and nuclear thermostats. I know , it is too simple. Cant help that.
