 Here’s some unedited feedback about K-Seal HD:

Having seen the results we are very impressed with this product.”  Commercial Vehicle Workshop Magazine

“”I recently purchased K-Seal HD (at Love’s Travel Centre in Broadwell, IL) for my 2002 Peterbilt that had a “mystery leak” in the cooling system.  So far your product has worked, about 35,000 miles and no coolant loss.”

“”I have a 2007 Cummins ISX (Heavy Duty engine) .  The EGR cooler was leaking coolant and the dealer said the only way to fix it was to replace it at $1300.  1 bottle of K-Seal (from Loves Travel Center) stopped it.  Saved a lot of $$$. ”
