![]() But is that the fault of Dex-Cool or the use of an inappropriate type of plastic? History proves that Dex-Cool does not damage gasketsĮven though everyone blamed Dex-Cool as the cause of gasket damage, history has proven that the leaks were caused by faulty gasket design. ![]() The Dex-Cool coolant may have reacted with the plastic. Some have claimed that chemicals in the Dex-Cool softened the plastic, eventually eating through it and causing the leak. Over time, the plastic softened, causing coolant to leak into the crankcase or out of the engine. ![]() Specifically, GM changed their intake manifold gaskets to a plastic carrier with silicone sealing strips around the edge. However, the root cause of the intake manifold gasket failure was the poor design of the gasket and not the Dex-Cool. The hole in this gasket was NOT caused by Dex-Cool. It’s true the intake gaskets in GM vehicles failed at an extremely After that, Dex-Cool gained a horrible reputation as a bad coolant and many shops recommended removing Dex-Cool and refilling with another type of long lasting coolant. Class action lawsuits were filed and GM offered settlement. GM switched over to Dex-Cool in their engines and shortly thereafter, the intake manifold gaskets in those same GM vehicles failed at an astounding rate. In addition to providing protection against freezing, Dex-Cool provides anti-corrosion and anti-foaming additives to prevent galvanic action and corrosion from forming in a vehicle’s cooling system. Dex-Cool coolant is based on an organic acid technology that provides longer life than traditional silicate based formulas. Repair Topics > Cooling System Service > What is Dex-Cool coolant?
