The 20905 part number is part of this line, offering a molded hose solution that fits select vehicle cooling systems requiring exact inside diameters and length.

Detailed Product Description

The Gates 20905 radiator coolant hose is made from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and automotive fluids. With an inside diameter of 1.5 inches (38 mm) on one end and 1.75 inches (44 mm) on the other, this hose accommodates specific radiator and engine connections. Its 16.2-inch (411 mm) centerline length ensures proper routing within the engine bay without kinking or stretching. The molded construction provides a precise shape that matches OEM contours, improving installation ease and coolant flow efficiency. This hose does not contain an internal spring, which allows for smooth coolant circulation without obstruction.

Common Applications and Issues Addressed

• Replacement for cracked or leaking radiator coolant hoses
• Prevents coolant loss due to hose degradation or swelling
• Resolves overheating caused by restricted or collapsed hoses
• Eliminates coolant contamination from hose material breakdown
• Restores proper coolant flow in vehicles requiring specific hose dimensions

Installation Notes and Tips

Ensure the vehicle is cool before removing the old hose to avoid burns. Verify the inside diameters and length match the original hose to maintain proper fitment. Use appropriate clamps to secure the hose ends without over-tightening, which can damage the EPDM material. Inspect adjacent components for wear or damage during installation. The molded design of the Gates 20905 hose facilitates alignment with OEM connection points, reducing installation time.
