The EPDM hose material is suited for heater hose use, while the dual I.D. layout supports connections where one end must step from 3\/4 inch to 5\/8 inch. This makes it a practical replacement for vehicles using a tee, pipe, valve, or intake manifold heater hose path. It is listed for 1994 Buick Roadmaster, 1994 Chevrolet Caprice, 1994 Chevrolet Impala, 1984-1986 Dodge Caravan, 1984-1986 Plymouth Voyager, and select 1982-1986 Ford Escort, Mercury Lynx, and Mercury LN7 applications. This part cross-references ACDelco 18005L and Gates 18076 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Fix\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCracked or hardened heater hose sections\u003c\/li\u003e\n\u003cli\u003eCoolant seepage at small-diameter hose connections\u003c\/li\u003e\n\u003cli\u003eRestricted heater flow caused by deteriorated hose material\u003c\/li\u003e\n\u003cli\u003eIncorrect hose sizing at tee, pipe, or valve connections\u003c\/li\u003e\n\u003cli\u003eLoss of heater performance from aging HVAC hose routing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the required end diameters before installation: 3\/4 in. on one end and 5\/8 in. on the other. Match the hose routing to the vehicle position listed for your application, such as Tee To Pipe, Pipe To Tee, Valve To Intake Manifold, or Heater To Pipe. Confirm the vehicle’s air conditioning and heater equipment notes before ordering, especially on Ford Escort, Mercury Lynx, Mercury LN7, Dodge Caravan, and Plymouth Voyager applications. Inspect adjoining pipes, tees, and clamps for wear before installing the new hose.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eDayco manufactures this heater hose to SAE J20R3 Class D-1 and SAE J1684 Type EC specifications for heater hose service.
