Review on Bar'S Leaks High Mileage Cooling System Repair, 16.9 Oz by Todd Look

My average running highway temp in my van has been around 210F for over a year. Recently, it started overheating, particularly in stop-and-go traffic, to about 250-260F. Noticed after pulling over steam was pouring out of the radiator. Tried this product and drove over 150 miles in both highway and city traffic and my engine temp never got over 170F and was averaging around 160F. I can't believe what a significant difference this stuff made and really wishing I had tried it a lot sooner!
