I am seeking comments regarding coolant mixtures. Has any one used treatments such as "Nalcool" that we use on the diesels.... or "Water wetter" that racers use to keep the temps down? TBH
Coolant
- Thread starter pamp
- Start date
With a good radiator, thermostat and water pump a 50/50 coolant and water mix should keep your temp around 4:00 on the gauge. I have never tried any additives.
I run closer to 55% Water and 45% coolant since water conducts heat better and I have no threat of freezing here anyway :razz:
More water is better than more coolant for sure.
Funny...something I have been thinking about as well. My coupe doesn't seem to like standing still. A number of issues could be contributing, but one quick stop gap plan was to add waterwetter.
Water may conduct heat better than coolant but the issue is when it reaches boling point it's contact is severely dimished. Coolant? Better in the sense it has a higher boiling point and so better contact above waters boiling point.
Water wetter? Reduces / eliminates air bubbles, conducts heat better than antifreeze. Works with glycol mixtures.
I run water and waterwetter in the Lotus as glycol antifreeze isnt allowed on the race track. Doesn't have freezing control abilities but that ain't my problem. Talk about a car that doesnt like standing still ....product works really well.
Good stuff...will help and certainly won't hurt!

Funny X 2,
On account of my only experience with "water wetter" was a Lotus show as well. Seemed to work on the Esprit, Cosworth w/ a Brian Hart head that I built. This was a hill climb and my customer placed first in class....the only car in that class! The gearing was totally wrong and I wished we had brought the Elan instead. The car that was fastest was a modified Datsun 510....300Z twin turbo for power. Awesome. Seems I need to experiment a bit on coolants, never one to be happy with status quo, but wanted feed back on the subject. So thanks....

I run about 1/3 coolant, 2/3 water with Water Wetter in my old BMW's.
Been doing that in my 2002 since early 80's....
And the CS since I bought it 4 years ago.
The 2002 (with a clean block, good WP and 3 core rad) never never ran hot. I even had the 80C TS installed.
The CS on the other hand... It does not like the warm weather. I need to fix that - probably go through the engine at the same time.
