Hey guys,,, I,m looking for as much advice on this before, turning wrenches or spending more money,,, I have a 250 in a 65 nova, mildly done, 4bbl, split exuast, most of the normal goodies,, this car will not cool well,, water pump,"new", radiator,"new", stock configuration, 3 core, super cool, right now I'm running the 1 piece flex fan,, the engine cruises 187-195 (florida),, but at idle (800+-rpm) the temp bounces 207,213, gone all the way to 221,hasn't overheated yet but has burped, the gauge is pretty accurate, 185 high flow stat,, "tested & good",,the rad core is 18"w and 14"tall,, the fan is 16",,no shroud,, these 6cyl cars originaly had none,,a v8 shroud is for a different rad,,I almost have a shroud built,, but I'm conviced this car should cool without it,,my last two theorys,, can a fan be to close to the rad,, mine is 13/16",, I had to add a spacer so the blade clears the pulleys,, or is it possible, the supercool rad(almost double the tubes and fins at three cores)has to much surface area and the fan can't pull through it,,this idea came by looking at a electric fan zip strap,, there is no way it would pull though the core, without destroying the fins,, has anyone delt with this,???
