Product Details

Ensure smooth operation of your Miata’s accessory drive system with the Gates K040378 Micro-V Serpentine Belt, engineered for 1990–1993 Mazda MX-5 Miata 1.6L DOHC engines. This OE-quality belt delivers reliable performance for critical systems like the alternator, A/C compressor, and power steering pump.

Built from durable EPDM rubber with a polyester tensile cord, the K040378 boasts excellent resistance to cracking, heat, and ozone exposure—substantially extending belt life compared to older rubber designs. Its 4-rib, 38-7/16-inch (977 mm) length and 0.56-inch (14 mm) top width meet factory specifications for a direct, drop-in replacement that ensures proper belt routing and tension.

Gates’ advanced belt construction reduces drive noise, helps prevent tension loss, and maintains optimal alignment—critical for both street and light-track use. This Micro-V belt is rated for long service life and backed by Gates’ commitment to OE compliance and customer satisfaction.

Whether you're replacing a worn belt during routine maintenance or building a track-prepped Miata with stress on belt-driven components, the Gates K040378 delivers dependable accessory drive performance. Choose Gates for a silent, smooth, and long-lasting serpentine drive solution.
