Detailed Product Description

The Gates Molded Coolant Hose 21968 is a molded radiator coolant hose made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals. This hose features two different inside diameters—1.27 inches (32 mm) on one end and 1.52 inches (39 mm) on the other—allowing it to connect seamlessly between varying radiator and engine fittings. With a centerline length of 36.6 inches (930 mm), it is designed to fit the cooling system layout of specific Cadillac Brougham and Chevrolet G30 vehicles. The molded construction ensures a precise shape that reduces the risk of leaks and improves installation accuracy.

The Molded Coolant Hose product line by Gates focuses on delivering hoses that are pre-formed to exact specifications, eliminating the need for bending or shaping during installation. This reduces installation time and potential hose damage, making it a practical choice for professional repairs and maintenance.

Applications and Common Issues Addressed

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to avoid burns from hot coolant. Verify that the hose diameters match the radiator and engine fittings on your Cadillac Brougham or Chevrolet G30. The molded design of the Gates 21968 hose allows for straightforward installation without the need for additional shaping. Use appropriate clamps to secure the hose ends and check for leaks after installation. Inspect surrounding components for wear or damage during replacement.
