Product Details
This Dayco Small I.D. Heater Hose is engineered for HVAC hose replacement where the heater circuit requires a dual I.D. connection between the pipe and heater. The EPDM rubber construction is suited to coolant transfer service, while the SAE J20R3 Class D-1 and SAE J1684 Type EC specifications provide the sizing and performance references used in heater hose applications. If you are replacing a worn heater hose on a Ford Focus, Dayco 87796 offers the correct fitment profile for 2000-2004 Ford Focus pipe-to-heater use.
What It Helps Fix
- Coolant leaks at a deteriorated heater hose
- Cracking or hardening from age and heat exposure
- Incorrect hose sizing at the pipe-to-heater connection
- Restricted heater coolant flow caused by a damaged hose
- Loss of cabin heat related to a failing heater hose
Installation Notes and Tips
Verify the end diameters before installation: 5/8 in. on one end and 23/32 in. on the other. Confirm the routing matches the pipe-to-heater position on the vehicle and inspect adjoining coolant components for wear before reassembly. This hose does not include a heat shield or protective sleeve.
Quality Assurance
Dayco manufactures this heater hose to meet listed SAE specifications for HVAC hose service. Part number 87796 is built as a direct replacement for the specified Ford Focus application and is also referenced by ACDelco 18173L and Motorcraft KH149.
