Red Line 80204 WaterWetter Super Coolant - 12 Ounce (2 Pack)

Purchased several times and pleased with the results

This stuff worked great on my classic car. Runs nice and cool now and no worries about overheating.

I’ve used this stuff for years and it definitely help coolants to stay cooler longer.

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.

This should be an automatic addition to every hot rod cooling system.

Been using this for years in all my cars. City traffic in the summer can be brutal on your cooling system. I noticed about a 10 - 15 degree difference in temps once I started using this - gauge still climbs in stop & go traffic with AC on, but generally stays below 230F now. It won't fix any mechanical issues in your engine - cracked head, etc - but it does help a healthy engine stay cooler.

I believe in the science behind this product but TBH I didn’t notice any change in coolant temperature. I like the Redline name brand. I live in Florida and quite often get stuck in traffic so it gives me a bit of peace of mind that I’m not going to overheat.

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.

Item is exactly what I ordered

Dropped the temperature of the V6 in my 1964 Sunbeam Alpine by 15-20°. Worked GREAT !!!

Put two bottles in and works well, came on time.

I have used this for years now in anything that has coolant. Awesome product. Great value and cooler running temperatures.

Good quality.
