The dual I.D. layout helps match different connection sizes without forcing an incorrect hose choice, and the EPDM material is suited to hot coolant service. For buyers searching for a heater hose for Honda Prelude or a heater hose for Chrysler and Dodge minivan applications, this part number 87720 covers the listed factory-style routing points.\u003c\/p\u003e\u003cp\u003eThe Dayco Small I.D. Heater Hose line focuses on application-specific hose sizing for heater circuits that need accurate diameter transitions. That makes it a practical choice when replacing a worn or leaking hose in systems that specify a 5\/8 in. to 3\/4 in. connection. Part number 87720 is also cross-referenced to Gates 18915 and 19150 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eReplacing a cracked or softened heater hose\u003c\/li\u003e\n\u003cli\u003eRestoring coolant flow through heater circuit plumbing\u003c\/li\u003e\n\u003cli\u003eAddressing seepage at hose-to-pipe or hose-to-valve connections\u003c\/li\u003e\n\u003cli\u003eMatching dual-diameter heater hose routing specified by the vehicle\u003c\/li\u003e\n\u003cli\u003eServicing HVAC coolant lines on listed Honda, Chrysler, Dodge, and Plymouth applications\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the routing point, inside diameters, and vehicle notes before installation.
