Review: Good Stuff - This stuff really works.I am very skeptical about additives in general,so when I heard about this product I really didn't expect the results I got.I was hoping this was going to prove me wrong and it did.I had a small antifreeze leak that I couldn't even find the source on my 2002 for taurus.I had changed the water pump about 6 months prior and this small leak kept showing up on the floor of the garage.I power washed the motor and still with mirrors etc. I could not find the source.I was told about this product and it worked.No more leaks and I didn't have to pull the water pump again.Ps. All hoses and clamps were find so it may have been sweating out from one of the bolts that secure the pump,but this did it.
