Mishimoto MMHOSE-GM-12L Silicone Lower Radiator Hose for 1973-1986 GM C/K Trucks
Description

Upgrade the cooling system of your classic GM C/K Truck with the Mishimoto MMHOSE-GM-12L Silicone Lower Radiator Hose. Designed for select 1973-1986 Chevrolet and GMC C/K Truck applications with 305 and 350 cubic-inch engines, this hose provides a durable replacement for aging factory rubber while maintaining dependable coolant flow and system pressure. Its black silicone construction delivers a clean, performance-oriented appearance suitable for weekend cruising, restoration projects, and show vehicles.
Unlike conventional rubber hoses that can become brittle, swollen, or cracked over time, the Mishimoto MMHOSE-GM-12L is constructed from five layers of silicone reinforced with heat-resistant embedded fibers. This multi-layer design improves resistance to engine-bay heat, internal pressure, and long-term wear, helping support reliable cooling system performance. The precisely formed lower radiator hose is designed for a secure fit on compatible GM C/K Truck cooling systems and helps reduce the risk of leaks when properly installed.
Installation is straightforward with the included high-quality worm-gear clamps, making this radiator hose a practical choice for replacing worn components during routine maintenance or a complete cooling system refresh. The hose is also backed by Mishimoto’s Lifetime Warranty, providing added confidence in the quality and durability of this Classic Line component. Verify vehicle year, engine, and application details before ordering to ensure compatibility; additional fitments may be listed in the application guide.

Features:

  • Five-layer silicone construction with heat-resistant embedded fibers
  • Designed for select 1973-1986 GM C/K Truck applications with 305 and 350 cubic-inch engines
  • Improves resistance to heat, pressure, and long-term hose degradation
  • Includes two high-quality worm-gear clamps for convenient installation
  • Black finish provides a clean appearance for classic trucks and restoration projects
  • Backed by the Mishimoto Lifetime Warranty
