Review on Derale 15731 Thermostatic Sandwich Adapter by Matt Campbell

As a result of using this product, I found that my engine was running cooler and more efficiently than ever before. The thermostatic feature allows for precise temperature control and the sandwich adapter design made for an easy installation process .The pros of this product definitely outweigh any potential cons, but I did have some difficulty finding the right size fittings for my particular vehicle. Overall, I highly recommend this adapter for anyone looking to improve their engine cooling system..
