Cyclo - Coolant Booster

I tried to cancel this within an hour of ordering. I wrote to manufacturer to insure it was compatible with any color antifreeze...they NEVER answered me. The manufacturer-seller also denied canceling the order because they said it was too late...an HOUR, yeah right! They just wanted to make a sale..did'nt care.ZERO customer service and VERY expensive. An entire of gallon of antifreeze costs the same and it is impossible to tell if this product makes ANY difference. I went ahead and pured it in since they denied a refund. NEVER again!

Actually it’s too soon to say. But I didn’t like the color of the conditioner. It turned the coolest a mucky brown. I have used this type of conditioner before and it was blue in color but I don’t know what brand it was. I was hoping to find that brand again. Only time will tell if this product works as well.

Works great
