Water Wetter....does it actually work?

I've used it, couldn't really tell any difference and i have an autometer full sweep gauge. It's only an $8 bottle so giving it a try is not the end of the world.

Just don't expect it to cure any cooling issues.
 
Agreed with 2000 - it's something to use as an extra barrier of protection and efficiency, but not to fix any issue. In other words, I wouldnt use it unless the system run great on its own already (or unless you run nothing but water, etc).

I wouldn't use it if your also running coolant. On www.bobistheoilguy.com a lot of people have had problems with a brown sitament(sp?) forming at the bottom of there rad. People who have had it using straight water have had a better experience using it.


That may explain why my radiator landed up full of brown crap.

Took me like 2 hours to clean the friggin thing out.
 
Same here...thought it might be rust..then I was worried it might be old oil deposits..nope black/brown gunk build up..the old overflow taken off was just a mess inside. I blame the water wetter for the mess for sure.
 
That's funny, I just bought a bottle today and was going to put it in tomorrow when I replace my water pump. My system runs cool and steady so we'll see if there is a difference. I'm going to have to upgrade to a bigger rad anyway so if it fills it with brown muck I'll know not do use it in the new rad.
