The molded profile helps match OE-style routing on applications such as the 2006-2009 Ford Explorer heater to pipe inlet, the 2002-2005 Mercury Mountaineer heater to pipe-1, and the 1990-1997 Mazda Miata heater to pipe-1. It also applies to the 2009-2010 Suzuki Grand Vitara heater inlet. This part cross-references Gates 18937 for the same application.\u003c\/p\u003e\u003cp\u003eThe Continental molded product line focuses on replacement hoses formed to match vehicle routing requirements, helping maintain correct coolant path through the heater circuit and bypass system. If you are replacing a worn heater hose on a Ford Explorer, Mercury Mountaineer, or Mazda Miata, Continental 63327 provides the specified molded configuration for those listed applications.\u003c\/p\u003e\u003ch2\u003eCommon Uses\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eHeater hose leakage at the molded section\u003c\/li\u003e\n\u003cli\u003eCoolant seepage at the heater core inlet or pipe connection\u003c\/li\u003e\n\u003cli\u003eCracking, swelling, or softening from age and heat\u003c\/li\u003e\n\u003cli\u003eRestricted coolant flow through a deteriorated heater hose\u003c\/li\u003e\n\u003cli\u003eIncorrect routing on a replacement Ford Explorer, Mercury Mountaineer, or Mazda Miata heater hose\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes\u003c\/h2\u003e\u003cp\u003eVerify hose routing, end diameter, and molded shape before installation. This hose is listed for multiple positions, including heater inlet, heater to pipe (inlet), heater to pipe-1, and heater to heater pipe (lower), so confirm the exact vehicle application before removal. On the 2002 Mercury Mountaineer listing, the note indicates cut-to-fit use with a molded hose configuration. Inspect adjoining clamps, pipes, and heater core connections for wear before installing Continental 63327.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eContinental 63327 is manufactured to SAE 20R3EC Class D1 and D2 requirements and includes resistance to electrochemical degradation for demanding coolant-system service.
