Have a 1939 chevy pick up with a 350 motor ,ac, on a s-10 chassis . I'm have an overheating iss ue , there is no anti freeze lose , no water in the oil and no white smoke from the tail pipe . I'm thinking there inst enough capacity in the aluminum rad or not getting enough air due to the cond in front of the rad . My question is if I replace the rad what type would offer the most effective treatment . 2 core ,4 core , single core ?And how is it sized ?

talk to a radiator shop on that but 4 core is your best option for this one. if it will fit as that is always the trouble with these type of setups.

I can't tell you the difference of single or double pass but I would imagine the double pass is more effective. best to talk to the people where you are getting the radiator from or look online. sorry.

Is the standard radiator fan a push or pull design . I'm thinking of adding it instead of another electric fan . However if the end of the blade folds back am I to assume this is a pulling fan ?

it may be a flex fan they used tomake them so it wouldn't takeso much power but if you have a fan on engine you'll also need a shroud otherwise it won't work so well that's why the electrics are so much better. Normal fans on car engines are pull fans, drawing air in through the radiator. But like I said you'll need a shroud if you add a fan driven from the engine.
