Dayco 87899 HVAC Heater Hose - Tee To Tee
Dayco Small I.D. Heater Hose for Ford Focus
Dayco 87899 is a Small I.D. Heater Hose built for HVAC heater hose service on select Ford Focus models. It uses EPDM construction for coolant resistance and includes a protective sleeve to help manage wear in routed heater hose applications.
Key Features
- EPDM rubber construction for heater hose use
- Black finish for a clean OE-style appearance
- Dual I.D. hose design with 3/4 in. end 1 inside diameter and 7/8 in. end 2 inside diameter
- Protective sleeve included for added abrasion protection
- Built to SAE J20R3 Class D-1 and SAE J1684 Type EC specifications
- Fits 2003-2007 Ford Focus, Tee To Tee
Detailed Description
Dayco 87899 is part of the Small I.D. Heater Hose line, a product line focused on heater hose routing where different inside diameters are required at each end. This dual I.D. hose is sized for a tee-to-tee HVAC connection and is listed for 2003-2007 Ford Focus applications. The EPDM material supports hot coolant circulation, while the protective sleeve adds an extra layer where the hose passes near other components.
This part cross-references Motorcraft KH352 and KH401 for the same application. Dayco 87899 is a direct-fit heater hose option for Ford Focus owners replacing a worn or damaged small I.D. hose in the HVAC system.
Common Problems This Hose Can Address
- Coolant seepage from a cracked or aged heater hose
- Softening or swelling from heat and coolant exposure
- Chafing where the hose routes near brackets or adjacent parts
- Restricted heater flow caused by a deteriorated hose interior
- Loss of heater performance from a leaking tee-to-tee hose connection
Installation Notes and Tips
Verify the end diameters before installation: 3/4 in. on one end and 7/8 in. on the other. Confirm the routing matches the tee-to-tee layout used on the vehicle, and inspect adjoining clamps, tees, and coolant passages before installing the new hose. Proper coolant refill and bleed procedures should be followed after service to restore heater operation.
Quality Assurance
Dayco 87899 is manufactured to SAE J20R3 Class D-1 and SAE J1684 Type EC standards for heater hose applications. The EPDM construction and protective sleeve support durable service in HVAC coolant routing on compatible Ford Focus models.
