Product Description

This Gates molded coolant hose is built for upper radiator hose replacement where the original hose follows a formed path and specific diameter transitions. The 1.25-inch to 1.5-inch end sizing and 17.3-inch centerline length support proper routing in the cooling system, while the molded construction helps match the factory hose shape. For Cadillac SRX and Cadillac STS cooling system repair, Gates 23028 provides a direct replacement format that aligns with the vehicle’s original hose layout.

Common Cooling System Issues It May Address

• Cracked or split upper radiator hose
• Coolant seepage at a worn hose section
• Collapsed or softened hose material
• Incorrect hose routing after prior repair
• Replacement of a damaged molded coolant hose on Cadillac SRX or Cadillac STS

Installation Notes and Tips

Verify hose routing, end diameters, and centerline length against the removed part before installation. Inspect adjoining clamps, necks, and coolant passages for wear or corrosion, and confirm the cooling system is fully drained and refilled according to service procedures. Because this is a molded hose, correct orientation matters for proper fit on the upper cooling circuit.
