About the Molded Coolant Hose Product Line

The Molded Coolant Hose line by Gates focuses on delivering hoses that are pre-formed to exact specifications, reducing installation time and improving fitment accuracy. This product line emphasizes durability and resistance to common coolant system stresses, making it suitable for vehicles requiring precise hose shapes and reliable performance, such as the Chevrolet S10 Blazer and Isuzu Hombre.

Detailed Product Description

The Gates Molded Coolant Hose 22039 is manufactured from EPDM, a synthetic rubber known for its excellent resistance to heat, ozone, and coolant chemicals. The molded construction ensures the hose maintains its shape and fits securely between radiator and engine components. With a centerline length of 17.7 inches (450 mm), and differing inside diameters on each end (1.49 inches/38 mm and 1.75 inches/44 mm), this hose accommodates specific coolant flow requirements without the need for additional clamps or modifications. The absence of an internal spring allows for unobstructed coolant circulation, reducing the risk of flow restriction or hose collapse under pressure.

Applications and Common Issues Addressed

• Replacement of worn or cracked radiator coolant hoses in Chevrolet Blazer and GMC Jimmy
• Resolving coolant leaks caused by hose degradation in Isuzu Hombre and Oldsmobile S15
• Preventing overheating due to compromised coolant flow in Chevrolet S10 and GMC Sonoma
• Addressing hose swelling or softening from prolonged heat exposure
• Eliminating coolant contamination from hose material breakdown

Installation Notes and Tips

• Ensure the engine is cool before removing the old hose to avoid burns
• Check hose connections for corrosion or damage before installation
• Use appropriate clamps to secure the hose ends firmly without over-tightening
• Verify the hose routing matches the original to prevent kinks or interference
• Inspect the cooling system for leaks after installation and during initial operation
