  • had the 38 out last week end with the kids. nothing new to car.

    outside temp was 92 degrees and car ran 205 down road.
    just after dark outside was 80 degrees and car ran 197.

    so the car is, if outside drops 10 degrees so does the car.

    new radiator is coming. copper.

    thank you stano41.

  • The shroud is always the key to good cooling. Just my experience. I have always used Walker because I prefer copper. Now that it's been sold I'm sure it will be cheapened up. Always seems to work that way. Guess I'll just buy Afco now, and use a shroud. I hate cheap junk. Getting to be good parts are harder to find, and good work is even harder to find.

  • I used a triple flow (called the dessert cooler) many years ago and it worked great...also used a (17 inch I think) steel fan and it cooled a bbc in my 36 ford...air flow is key and making sure it comes through the radiator (i.e., shroud)

    1. The original radiator looks like a bee's honeycomb. The top neck is 1 3/4".
    2. You answered your own problem = fan blade is 4" to 5" from the radiator. I have 18 different fan blade spacers if you want
    one, but 4" are not made.
    3. I was a dealer for Walker, my fav, for 35 years. But Vernon closed the business 4 months ago. The ancient Egyptians
    discovered that copper and brass is a greater heat disapator then aluminum.
    4. What fan are you using ? 4,5 6 blades ? Deep pitch ? Tapered flex fan race garbage ?
    5. A long water pump will put you closer.
    6. Like Jeff/Tazhog sez, Cooling Components puller with shroud will fix it if radiator is modern. Never use a pusher.
    5. Your problem is typical since the first time a hot rodder instaled a 265 in place of the longer 6 cylinder...circa 1955. I have
    done many since 1957.
    6. Run a 180* stat to keep water in the radiator longer. 16# cap if a modern radiator.
    7. Check your timing.
    My first hot rod garage was called CHEVY SPECIALTIES. I would install ONLY a SBC in your 1952 Jeep, 53 Vette, 62 Volvo, 34 Nash Brougham, 61 Jag, 56 Austin Healy, or the usual cars.
    Jim, bangin' on old cars since 1957.

  • We just put the order in for USRadiator. 1938, copper, 4 row, down flow, we put the trans cooler in it but might not even use it. They said it takes 4 to 5 weeks as they are made to order.

    now work on shroud and a new fan.

    thank you for your help

  • i agree with the more rows of tubes the last one could be maybe only 15 per cent. I also saw a 66 chevy a guy had put in a new radiator that was a four row and the radiator had two row tanks on it. we looked and the rows were the smallest tubs i ever saw. It still over heated..

    Not much choises with copper radiators out there.

    thank you stano41

  • I used Brice Thomas on my '39. It's a two row and cools the LS just fine BUT the LS is easier to cool. At some point there is diminishing returns on the number of rows due to blocked air flow. Size of the tubes is also a factor. Of course the more air across the ENTIRE core the better. Not only are shrouds and fans a factor the ability of the air to exit the engine compartment is a factor too.

  • The more cores you have will hold more fluid ,, but when you do thicker cores the air flow goes down So you have to have a bigger fan blades with more pitch to pull the air thru the radiator ! A three core would be the best as your factory one is 2 core ! As I stated in a earlier post a electric fan with a shroud will solve your problems and the car will run cool just don't cut corners on quality !. .

  • i am not finding a lot of advice online. the positive points are coming from only companies that sell tripple flow radiators. not finding any positive points from users of tripple flow radiator.

    one user said made no difference and why should it because the core was same specs on down flow as tripple flow. he said core is what cools.
    another said had to increase flow to get tripple flow to work better
