Anyone used one of those addatives that's supposed to lower your coolant temp? They're referred to as "wetting agents". Any recommended brands....and do they work?

Thanks!

I think coolant additives are a waste of money, unless you live in northern Canada or Nevada. I use good old dihydrogen monoxide, straight from the tap.

I have run straight water, a water pump lubricant, and redline's water wetter.
It worked to the tune of about 10-15 degrees. If you run it mixed with coolant the drop will be less.
How it works, I don't know I'm not a chemist I was given a tip to try it and did...

Royal Purple "Purple Ice" does indeed lower the engine temps by 10-15 degrees as tested by us.

I bought a Mustang that the guy sold because it was a boiler. He didn't have a shroud, which was added and a bigger radiator which was added and the timing was changed. It came down and was passable but I added some stuff called water wetter and it did lower the temp. The car had a fresh 60 over engine!! I sold the car and it was driven North without incident. Is Purple Ice the same kind of additive?

It's similar Pete. Basically it is heavy water.

I use Purple Ice in my race motor. It does help keep the temp lower even in my filled cleveland.

Wow, that means it doesn't absorb neutrons, which means you can run on unenriched nuclear fuel
Maybe I'm gonna try some of this stuff after all!

While we're at it what is the best combo of coolant and water for a performance motor? I am probably at about 70% water & a bottle of watter now.

Coolant?? as in antifreeze?
None, all water and a bottle of Purple Ice and a bottle of water pump lube.

Doesn't that reduce the boiling point? Is it okay to run all water in a street car? I was thinking that it would boil over sitting in traffic without some coolant/anitfreeze. It's never cold enough here to freeze so I have been running it just to raise the boiling point.

Anti freeze raises the boiling point by inhibiting waters capability to transfer away heat. I have never used any anti freeze in my street car. Either it does work that way, or I'm just plain lucky since I never had one boil over.

A good radiator cap, a good water pump and a good radiator and it wont boil over.

Have used Prestone for years - it raises the boiling point, has a lubricating feature and reduces rust ie freeze plugs-usually around 50/50.

Actually that's what I meant, raising the boiling point. I have two electric fans an SVO late model(crossflow) 3 core radiator and an Edelbrock water pump. The car runs completely cool even if rolling slowly but at idle it slowly works its way up. It hasn't overheated even after 30 mins in stop and go traffic but it seems like it would if I gave it enough time.

I use straight distilled water and water wetter. That's it no pump lub. or anything, since water wetter is supposed to have it in there anyways.

I have driven my car up to Reno, NV twice this year(100+ degree weather) from San Francico (60 degree weather) and haven't had a problem in traffic. But I used to before the water wetter!

I'm running 50% Havoline coolant and 50% distilled H20. Would my motor run cooler with, say, 70% water and 30% coolant? Cooler yet with 70/30 + water wetter (the purple stuff)?

I live in southern Ohio where it freezez hard in winter so I must have at least 30% antifreeze.

I would tihnk if youl ive in are where it freezes, like Brian, you shouldn't mess with lowered amounts of anti-freeze, assuming you don't have an overheating problem.
Havving a motor that won't overheat doesn't mean much if it cracks the block form freezing solid during winter
as always, YMMV
