Radiator Hoses

Ditch the Flex Hose: Molded Vintage Radiator Hoses

There is nothing that ruins the look of a restored engine bay faster than an ugly, ribbed "universal" flex hose. More importantly, generic hoses often rub against alternators or fans because they lack the specific bends required for your engine.

At Old Car Parts NW, we stock authentic NORS (New Old Replacement Stock) and molded replacement hoses that fit right and look factory-correct.

Why Choose Molded Hoses?

  • Perfect Fitment: Our hoses are molded with the exact curves and angles designed by the vehicle manufacturer. This ensures they clear your belts, fan, and air cleaner without kinking or chafing.

  • Better Flow: Unlike ribbed flex hoses which create turbulence and restrict coolant flow, molded hoses have smooth interior walls for maximum cooling efficiency.

  • Complete Selection: We carry the hard-to-find Bypass Hoses (often overlooked until they burst) and shaped Heater Hoses for specific Ford, GM, and Mopar applications.

Inventory Includes:

  • Upper Radiator Hoses: The main connection from the thermostat housing to the radiator.

  • Lower Radiator Hoses: Often containing the critical anti-collapse spring (check specific listings).

  • Bypass Hoses: Small, critical hoses for water pumps on V8 engines.

  • Bulk Heater Hose: High-quality rubber for cabin heating loops.
