OEM GM winter cover for your truck during the winter months. Duramax engines utilize two thermostats and during cold weather, the engine may never get up to the proper operating temperature. These covers will help maintain proper engine operating temperature which will ensure faster warm ups and better fuel economy. Easy installation, no drilling required.
