Water Wetter - LEGIT?

[treegump]

I've seen many people (it seems) talk about puting water wetter in their cooling system. Is this stuff legit? and where do you buy it from?

I used it in Texas summers, and it made a big difference, but seems to quit working after about a year, or maybe something else was affecting it. IIRC, Works great for maybe a year, then flush and fill w/ fresh antifreeze and water wetter.

I don't use it any more, the 'Burb is the only sweat horse, and I use Evans coolant in it.

I've had great luck (contrary to some people's opinion) with the regular GM Dex-Cool... never ever had a problem with overheating, flushed it and replaced t-stats at 175k, heat's always hot in the winter and the fan barely kicks on in the summer unless I'm in traffic (even when its 90-100+)...

It helps. Used it in my Hot Rod Trailblazer SS that required a bigger than factory radiator to stay cool out here and the 08 Duramax. The Duramax I ran hot enough to ruin 350 degree oil cooler hoses and the coolant hoses - yet never had a boil over. (245 ECT was normal for me pulling hills.)

We used it in the late model racecar and it helped alot.

Yes it works. I used it in a friends 64 vette with a hot 327 in it that would overheat at redlights. Just remember though that most of them work best with water, and anti-freeze takes away from it's efficiency.

ditto;
some of us in Texas used just distilled h2o and Redline water wetter

I put it in my Tahoe. Made no difference.

X2 for the 194K on the truck, and 145K on Burb, Dex Cool in both clean rads/ac condenser core, fan clutch working, stats working; are all crucial South Ms/Ga summers are about hot as most places get

Its weird - but after it warmed up to 40 degrees for a couple of days, my factory gauge actually shows that the my coolant temp stays about 5-10 degrees cooler than when I originally asked this question. I'm thinking I must've gotten some ice buildup on the fins, or something? Now it hovers right around 190...and when I get a chance I hope to flush the system and do a more thorough cleaning of the radiator, along with the DIY fan clutch adjustment

Ice buildup in the fins would've made it a LOT cooler. While it does block airflow, if the outside surfaces of your radiator are cold enough to keep ice, you can be damn sure your coolant is pretty cold.

You forget the "gap" between the not in use AC condenser and hot radiator. The condenser can ice up or plug with snow esp in blizzard conditions. This can overheat your engine. Been there done that... Some of use may have an oil cooler in front of the condenser to keep 1/2 of things melted...

I suggest that the OP replace the temperature sender for the gauge. Mine had some corrosion on the contacts and quit reading anything close to accurate. The first like reading one evening while the trans was at 210 was a dead giveaway.
