Review on Aluminum Coolant Thermostat 2001 2010 Duramax Replacement Parts by Sol Nuttbrock

I recently purchased a replacement part for my automotive engine cooling system. My analysis of this product showed that it IS made of sturdy aluminum material, which is great for durability and longevity. It fit perfectly in my 2001 - 2010 Duramax vehicle series. i was pleased with its performance; it maintained a steady temperature and improved my engine`s efficiency overall. One small con was that it came without any instructions, but a simple online search helped me with installation.Overall I would recommend this product to anyone in need of replacement parts for their automotive engine cooling system..
