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

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

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

The first time I used this was at the race track. I put it in per the recommended dosage and it did everything the salesman said it would. That was in 1993 and I still use it in all my cars.

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

As advertised and just what I needed

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.

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.

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.
