Gates HVAC Heater Hose P/N:12256
Keep coolant flowing to the heater core with the Gates heater hose 52103, a modular coolant hose that drops in as a direct-fit replacement for the 2004-2008 Ford Ranger and 2005-2006 Mazda B3000 (see the Buyer's Guide tab for engine-level details). As part of Gates' modular assembly coolant-hose line, it is built for specific applications and integrates the OE components the routing needs — quick-connectors, branch connectors/tees, sensors and restrictors where applicable. Depending on your vehicle's plumbing it serves the heater-to-valve, valve-to-engine, engine-to-heater or heater right-side runs.
Gates recommends fitting new clamps whenever a coolant hose is installed. Do not use for fuel or oil transfer applications.

What is the hose made of?
It has an EPDM tube with synthetic fiber knit reinforcement and a heat-, ozone- and chemical coolant-resistant EPDM cover, and its materials are engineered to resist collapse under vacuum.
Do I need new clamps when I install it?
Gates recommends replacing the clamps each time a new coolant hose is installed to help ensure a secure, leak-free connection.
Can I use this hose for fuel or oil lines?
No. This is a coolant hose only — Gates cautions against using it for fuel or oil transfer applications.
