Product Details

Dayco Small I.D. Heater Hose 88501 is made for heater outlet service on 2011-2014 Ford F-150 models. The branched layout supports the factory hose routing, while the EPDM material is suited for heater hose use in the cooling system. If you are replacing a worn or damaged Ford F-150 heater hose, Dayco 88501 provides the correct small I.D. configuration for this application.

The Dayco Small I.D. Heater Hose line focuses on replacement hoses with OE-style fit and material selection for HVAC and cooling-system routing. This part number, 88501, follows that product line approach with a branched design and protective features for underhood use.

What It Helps Fix

  • Coolant leaks at the heater outlet hose
  • Cracked or hardened heater hose material
  • Restricted coolant flow through a damaged branched hose
  • Heat-related wear on exposed hose sections
  • Improper hose routing after a failed replacement hose

Installation Notes

Compatible With 2011-2014 Ford F-150, heater outlet. Verify hose routing, end diameters, and overall length before installation. Inspect adjoining clamps, fittings, and coolant passages for wear or contamination before installing the new hose. Dayco 88501 should be matched to the original heater outlet configuration for proper fit.

Quality Assurance
