When you buy a product, how do you know beyond the marketing promises that it’s any good? Independent testing is the answer. Because the market for coolant leak repairs is competitive, Kalimex has embarked on a two year independent testing research project with the internationally renowned engineering division of Brighton University. K-Seal together with other head gasket and coolant leak repair products has been tested according to the stringent American Standard D-3147 over many months. The researchers concluded that “K-Seal has successfully completed two entire test sequences in succession in accordance with test methods set out in ASTM D3147.” The researchers found that K-Seal was (by a big margin) the most effective permanent coolant leak repair at sealing large and small holes compared to the nearest competitor.
