Thread: cooling tips

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?

I've used water wetter in the past with my old cooling system and it works... I think I saved about 20 degrees (F) without any other changes... I haven't used it in my new system as it cools well. Anyway, water wetter is a good product in my opinion.

I'm guessing this is partly the reason my temp goes to 90C when idling in hot weather (normal operating temp is 82C)

Remove the shroud, and pop rivet some black plastic (get at any shop that builds or works on race cars, lotta those in Richmond). Put on the back side of the shroud, would not be very noticable. Probably some good black high temp silicone would work, let it dry throughly.
You go to the Williamsburg Rod Run? Not as good now as when at the Best Western.

I you cannot get some plastic I have went to a hardware storeand purchased a small peice of sheet metal and bent it to fit.and screwed it to the shroud. Good luck

My 64 C 10 coolant looks like mud. I have repeatedly flushed it, and it keeps coming back. It also has an overheating problem. I have ( mostly ) corrected the overheating by adding an aluminum 2 core radiator as wide as ill fit in, an electric fan on a thermostatically controlled relay, and an oil cooler. Still overheats at idle though.

you may want to check to make sure you have good air flow across your radiator when the fan is running.make sure the fan is pulling air from the front of the truck and not pushing air out.as far as the mud! it can be very hard to get rid of and you may not beable to get rid of it short of having your block boiled out. I would try and have flushed professionally by a radiator shop then add a can of rust inhibitor made for cooling system. hope this helps (keep me posted)
