Technical Description of Part Number 21379

Part number 21379 features a molded construction using EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals. The hose includes an internal spring to maintain shape and prevent collapse under vacuum conditions. Both ends have an inside diameter of 2 inches (51 mm), making it suitable for radiator connections requiring this size. The 20-inch (508 mm) centerline length ensures compatibility with specific vehicle cooling system layouts. This hose does not include quick connect fittings or branches, simplifying its use in standard radiator coolant circuits.

Common Applications and Problem Solving

• Replacement of worn or cracked radiator coolant hoses
• Prevention of hose collapse due to vacuum pressure with internal spring
• Maintaining coolant flow integrity in vehicles requiring 2-inch diameter hoses
• Addressing leaks caused by degraded or brittle hoses
• Ensuring proper fitment with molded hose design for specific radiator connections

Installation Notes and Tips

Ensure the hose is compatible with your vehicle’s radiator connections by verifying the 2-inch inside diameter and 20-inch length. The molded shape facilitates alignment with existing coolant system ports. Inspect hose clamps and surrounding components during installation to maintain a secure, leak-free connection. Avoid twisting or stretching the hose excessively to preserve the molded form and internal spring integrity.
