Review on π‘οΈ Enhance Engine Cooling with Design Engineering 040104 Radiator Relief Coolant Additive, 32 oz. by Brian Motley
It did not work. - Radiator
I have a 1993 Suburban 454 4x4 that gets very hot most of the time. I bought this product hoping it would work as promised. But that's not the case. In fact, my car seems to be running HOT. So I don't recommend it and I won't buy it again!
Pros
- Contains corrosion inhibitor and reduces existing deposits
Cons
- Not sure
