anybody here use redline "water wetter" ? and if so..results?

JettaRed

I used it in my 2000 VW Jetta years ago and it caused the coolant to become brownish with some sediment. VW uses the same G-12 coolant, so I would NOT recommend it. The G-12 is pretty good stuff, so don't mess with it.

BTW, the Water Wetter did not lower coolant temps as claimed.

I have heard that for cars such as ours, water wetter and similar products will do nothing. Essentially, the Audi's systems will keep the car within a specified range of temperature, opening and closing portions of the radiator and using the fan as needed. That is a closed block design. Those cooling products only work in open block designs; cars and motorcycles that have a radiator whose full capacity is open to the engine at all times.

Exactly how do portions of the radiator open or close? I think you're on crack

Hey, my experience is in the open block world, I have no idea... haha, I found a website from the coolant company that makes engine ice, a product I use in my motocross bikes; http://www.engineice.cc/auto.html

That explains that their product will not make a big difference in modern cars. Water Wetter operates on the same principles.

being pumped through the radiator. In no way is the radiator altered. The fans are also thermostatically controlled to only turn on when needed.
