  • Great addition for my PCP Air Compressor
It works great to help lower the temperature on my Yong Heng PCP Air Compressor. Just follow the instructions to mix with amount of water.

  • Works good
My system holds about 1.5 gallons so I put half a bottle in. 150-160f op temp, 180 fan switches on 160 off, before my fan would switch on regularly and take a while to turn off in normal driving with straight distilled. Floored it, not exaggerating, for a solid 2 hours straight on mountain roads after putting it in and the fans never switched on. Temp was constantly at bottom of op temp range on temp gauge so likely around a 10f reduction overall. Oil was overheating before the water did, who knows if that's a testament to my poor oil cooling or good water cooling but I'm happy with it. I think I paid around 30 for the 2 pack so good value. ... show more

  • Never used before now. Seems to be working well.
I have a 1984 Suburban with a mild performance built, 400hp to the crank, 1979 350 motor and 700r4 trans. I've don't drive it a lot but I've got about 500 miles on it over the last 1.5 years. I've noticed in the summer (North Florida) when I sit in traffic, that the temp seems to creep up about 215-220. I have a new stock-style water pump, a Flex-A-Light fan (properly sized and positioned in the fan shroud), a 192 degree t-stat, and proper 50-50 mix coolant. I drained the coolant, installed a 180 degree t-stat and fresh coolant with this Waterwetter. Seems to be working well. Hasn't got over 200 yet. ... show more
