Product Details

Gates Molded Coolant Hose part number 51561 is engineered for application-specific fitment on the Mazda 5 heater system. The molded design helps maintain the correct hose path, while the integrated OE-style components support the original connection layout used in the vehicle. This hose is listed for 2006-2010 Mazda 5 models in the lower heater position and is a direct-match service part for that application. Gates 51561 is also cross-referenced to Monroe Shocks & Struts CC446124YB for the same application.

The Gates molded coolant hose line is focused on modular coolant assemblies that mirror OEM-style configurations. For this application, that means a hose built around the required bends, branch, and connector interface rather than a universal cut-to-fit design. If you are servicing a Mazda 5 heater hose leak or replacing a damaged molded coolant line, this part number 51561 provides the correct shape and connection style for the listed vehicle fitment.

Common Problems This Part Can Address

• Coolant seepage from a cracked or aged heater hose
• Loss of heater performance caused by restricted coolant flow
• Leaks at the hose branch or quick-connector interface
• Improper routing after a previous hose replacement
• Heat-related deterioration of the original molded hose

Installation Notes and Tips

Confirm the vehicle is a 2006-2010 Mazda 5 with the lower heater hose application before ordering. Inspect the mating connectors, clamps, and nearby plastic fittings for wear or damage before installation. Transfer only the components required by the vehicle configuration and verify that the hose follows the original routing without twist or tension. After installation, refill and bleed the cooling system according to Mazda service procedures and check for leaks at operating temperature.
