Gates 97-05 Mazda Miata HVAC Heater Hose - Gates 18010

Keep your Miata’s heating and coolant systems working dependably with the Gates 18010 Small-ID Molded Heater Hose, engineered for 1997–2005 Mazda MX-5 Miata 1.8L (NA/NB Gen). This premium molded hose serves as the critical connection between the thermostat housing and water pump—the “pipe-to-throttle body” or “HVAC” coolant/heater path—ensuring consistent coolant flow and cabin heat performance.

Constructed proudly with factory-molded OE-style profile, the 18010 is crafted from high-quality EPDM rubber, complete with synthetic fiber reinforcement and cover. This construction provides outstanding resistance to heat, ozone, coolant corrosion, and vacuum collapse—making it especially reliable under the stress of track-day conditions and extended spirited driving.

Rated for a broad temperature range (−40 °F to +275 °F / −40 °C to +135 °C), this hose meets SAE 20R3 Type EC and Class D-1/D-2 standards, delivering long-term resilience in both street and track contexts. The precise molded design ensures correct routing, clamps securely, and keeps hoses from chafing against adjacent components—reducing maintenance headaches.

Easy to install with standard hose clamps and no special tools required, the Gates 18010 is the go-to replacement for worn or cracked heater hoses. Miata owners looking to maintain reliability, cabin comfort, or performance driveability will appreciate the engineered fit, OE compatibility, and part reliability from Gates.
