Detailed Product Description

The Gates Molded Coolant Hose 23945 is engineered to meet the specific cooling requirements of the Scion iQ. Its molded construction eliminates the need for multiple hose segments, reducing potential leak points and improving coolant flow efficiency. The EPDM material offers resistance to heat, ozone, and coolant chemicals, which helps maintain hose integrity under demanding engine conditions. With a centerline length of 16.42 inches (417 mm) and consistent inside diameters of 1.19 inches (30 mm) on both ends, this hose fits precisely within the cooling system layout of the Scion iQ.

The Molded Coolant Hose product line by Gates focuses on delivering pre-formed hoses that match OEM specifications, ensuring proper fitment and reliable operation. This line is designed to simplify installation and reduce maintenance issues related to coolant hose failure.

Common Applications and Problem Solving

  • Replacement of worn or cracked radiator coolant hoses in Scion iQ vehicles
  • Prevention of coolant leaks caused by hose degradation or improper fit
  • Restoration of proper coolant flow to avoid engine overheating
  • Elimination of hose collapse or kinking due to molded design
  • Addressing coolant system failures related to hose material fatigue

Installation Notes and Tips

Ensure the engine is cool before removing the old hose to prevent burns or coolant spills. Verify that the hose dimensions match the original part, focusing on the 1.19 inch (30 mm) inside diameters and 16.42 inch (417 mm) centerline length. Use appropriate clamps to secure the hose ends without over-tightening, which can damage the EPDM material. Inspect surrounding components for wear or damage during installation to maintain overall cooling system integrity.
