Coolant temps came down noticeably
Running WaterWetter in my track car for a couple seasons now and the temp reduction is real. On a hot day at the track I was seeing coolant temps run about 10 to 15 degrees lower than before I started using it. The two pack is a great deal since you go through it faster when you flush the system regularly. This stuff has earned a permanent spot in my prep routine.

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

Love this stuff....
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.

Good but no noticeable change
I believe in the science behind this product but TBH I didnโt 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 Iโm not going to overheat.
