The B-66-27-26-S-G-T-J kit comes with six key components: a high-performance coolant bypass valve, two coolant hoses, two hose clamps, and an installation instructions manual. Each part is meticulously engineered to ensure a perfect fit and seamless integration into your vehicle's cooling system.

The coolant bypass valve is the heart of this kit. It is a high-quality, heavy-duty, and durable component designed to regulate coolant flow between the engine and transmission. By allowing excess coolant to bypass the transmission during cold starts, the valve helps prevent transmission damage caused by frozen coolant and ensures a smoother operation.

The two included coolant hoses are crafted from premium materials, such as reinforced rubber, ensuring resistance to wear, tear, and the harsh effects of extreme temperatures. These hoses are engineered to fit securely in place of the original hoses, allowing for easy installation and improved cooling system efficiency.

The kit also includes two hose clamps for secure installation of the new hoses. Made from strong and durable materials, these clamps will not strip or break easily, ensuring a long-lasting and reliable connection.

Lastly, the installation instructions manual provides clear, step-by-step guidance for installing the bypass kit. The process is straightforward and can typically be completed in a few hours by an experienced DIY mechanic or in less time at a professional repair shop.

In summary, the B-66-27-26-S-G-T-J Freeze Coolant Bypass Kit is an essential upgrade for owners of 2003-2007 Dodge Ram 5.9L engines and 2007.5-2018 Cummins 6.7L engines.
