Rated 5 out of 5 by from Very convenient. Love the fact that it works with all makes models. Purchased a radiator and the coolant. I didn't have to drain the whole system due to the fact that this product works with all makes and models. After installing the radiator, i filled the system up and have had no problems. Overall a good product.

Rated 4 out of 5 by from Just Add Water is not clearly instructed I added this AntiFreeze to my radiator & reservoir without knowing I had to add 50% water. The instructions to do so are not in large bold print and should be written more than once so consumers have no doubt whether or not to add 50% water.
