Upper Hose 183-8119 for Caterpillar CAT Engine 3066 Excavator 320C 320CL

This upper radiator hose was exactly what I needed for my truck. The quality is impressive—it’s thick, flexible without feeling cheap, and the molded shape matches the original perfectly. Installation took less than 10 minutes; it slipped onto both the engine and radiator connections snugly with no leaks. I’ve driven about 500 miles since replacing it, including some towing in hot weather, and it’s held up perfectly with no swelling or softness. For the price, this hose is a steal compared to parts store brands. Highly recommend for anyone needing a reliable cooling system replacement!
