Review on Dewhel JDM Aluminum Coolant Thermostat Plug For GM 2001-2010 Duramax 6 by Todd Kiser

Based on our own experience this thermostat plug upgrade effectively improved the cooling performance of our GM Duramax engine... It is made of high-quality aluminum material that ensures durability and longevity. The installation process was a breeze and we noticed an immediate improvement in our engine's performance. The only con we found is that it may not work with all engine models, so make sure to check before purchasing. Overall, we highly recommend this product to anyone looking for a reliable and efficient engine cooling upgrade..
