Thread: cooling tips

One cooling problem not yet mentioned is one peculiar to our hobby. Stuffing a big engine in a tight engine room often leaves nowhere for the cooling air to get out after passing through the rad. Often the car is lowered, so the air can't get out underneath, either. Sometimes it will blow out the front, under the bumper, and be drawn back through the rad, reducing the cooling even more.
I put a Dodge Red Ram hemi in a '39 International and had to remove the inner fender panels to get it to cool. Ran it for a while with no hood, that worked too, but I didn't like the look.

if you used header bags, it would keep a lot of the header heat out of the engine compartment....... but there's only so much you can accomplish and they aren't exactly cheap

do the cooling additives like 40 below, 28 below, water wetter, etc., really help cool the radiator down more? & I'm curious(if there is anyone who really knows) the two product probleand make 28 degrees below, & 40 below, as their names inply they are suppose to lower radiator temp 28 degrees & the other 40 degree, do they really work that much, or are they snake oil?
