Detailed Product Description

The Gates Molded Coolant Hose 21140 is designed to replace original equipment radiator coolant hoses in compatible Audi and Chevrolet vehicles. Made from EPDM, a synthetic rubber known for its resistance to heat, ozone, and coolant chemicals, this hose maintains integrity under demanding engine conditions. The molded construction ensures the hose matches the original shape and dimensions, with end diameters of 1.22 inches (31 mm) and 1.28 inches (33 mm) and a centerline length of 11.1 inches (282 mm). This hose does not contain an internal spring, which allows for unobstructed coolant flow and reduces the risk of clogging or damage.

Common Applications and Issues Addressed

• Replacement of worn or cracked radiator coolant hoses in Audi 100, 100 Quattro, 5000 Quattro, and Chevrolet Corvette
• Prevention of coolant leaks caused by hose degradation or improper fit
• Restoration of proper coolant flow to maintain engine temperature regulation
• Elimination of hose collapse or deformation under pressure
• Addressing overheating issues related to faulty or damaged radiator hoses

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to avoid burns. Verify that the hose dimensions match the original equipment specifications, particularly the inside diameters and centerline length. Use appropriate clamps to secure the hose ends without over-tightening, which can damage the hose. Inspect surrounding components for wear or damage during installation to maintain overall cooling system integrity.
