Heater Hose line focuses on replacement hoses for heater and HVAC plumbing where the hose diameter changes between connection points. Part number 87633 uses EPDM rubber for heat and coolant exposure in heater circuits, and its dual I.D. layout supports applications that transition from a 5\/8 in. connection to a 3\/4 in. connection. This makes it a practical replacement for vehicles such as the 2006-2008 Ford Explorer heater to valve routing, the 1996-2000 Honda Civic heater outlet, and the 2004-2005 Chevrolet Impala lower heater pipe connection.\u003c\/p\u003e\u003cp\u003eFits 2006-2008 Ford Explorer, Heater To Valve; Fits 2008 Ford Explorer Sport Trac, Pipe To Pipe (Inlet); Fits 2006-2007 Mercury Mountaineer, Heater To Valve; Fits 2004-2005 Chevrolet Impala, Heater To Pipe (Lower); Fits 1996-2000 Honda Civic, Heater Outlet.\u003c\/p\u003e\u003ch2\u003eWhat It Helps Address\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eCracked or hardened heater hose material\u003c\/li\u003e\n\u003cli\u003eCoolant seepage at a worn hose connection\u003c\/li\u003e\n\u003cli\u003eIncorrect hose diameter at a transition point\u003c\/li\u003e\n\u003cli\u003eRestricted heater flow caused by deteriorated hose walls\u003c\/li\u003e\n\u003cli\u003eService replacement for aging HVAC heater plumbing\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify both end inside diameters before installation: 5\/8 in. on one end and 3\/4 in. on the other.
