Cooling system

Hi,

Has anyone had any experience of this ?

RANGE ROVER P38 V8 ENGINE WATER WETER COOLANT -40 DEG | eBay

Well known within the racing boys, but a well maintained standard system is to best bet.

Reducing the temperature is not necessarily a good idea. An engine needs to run at the correct temperature for the best performance/economy. It will not stop overheating if there is a problem.
On race cars it could be used to allow a smaller rad to be designed in, assuming that it actually works.

well the American speedway racers say its good, they also reccomend "water wetter". no too sure about the mix ratios though, seems a bit funny to me.


"Keyser Manufacturing 40 Below coolant additive is designed to reduce coolant temperatures by up to 40 degrees F. It can stop your radiator from overheating and is ideal for racing or other high performance engines. The additive maintains coolant temperature between 180-210 degrees F when one 30 oz. can is added to a mixture of 80 percent distilled water/20 percent ethylene glycol (antifreeze)."

"Reduces coolant temps up to 40° F. Prevents coolant temperature from rising excessively under extreme racing conditions. 30 oz. Use a 80% water and 20% Pro-Blend 40 Below mix.

NOTE: Do NOT use with propylene glycol antifreeze, stop leak, or block sealer. Can be used with distilled water and ethylene glycol antifreeze."

Standard coolant does exactly the same thing, that is why antifreeze always finds leak points where none existed before. All these things do is reduce the surface tension of the water in the rad. Very expensive snake oil in my view.
