This coolant reroute tube is a must - have for 2004.5 - 2007 GM vehicles with 6.6L LLY/LBZ Duramax engines. It's crafted from 304 stainless steel, which is far superior to the OEM mild steel pipe as it prevents rusting and leaks. The tube is designed to work seamlessly with the original thermostat housing. Its straight design makes it a great fit for larger intake bridges. And guess what? It's also perfect for marine use! Part Number: 119000300. Key features include compatibility with the factory thermostat housing, a straight design for larger intake bridges, stainless - steel construction, and suitability for marine applications.

Using this coolant reroute tube is easy. First, make sure your engine is cool. Locate the old coolant tube and remove it carefully. Then, install the new tube in place, ensuring it fits well with the original thermostat housing. When using it with a larger intake bridge, double - check the alignment. As for maintenance, keep an eye out for any signs of damage or leaks. If you notice any issues, address them right away. Since it's made of stainless steel, it's quite durable, but avoid using harsh chemicals when cleaning it. And if you plan to use it in a marine environment, rinse it with fresh water after each use to prevent saltwater corrosion.
