Ensure reliable coolant flow with the Gates 20661 Molded Coolant Hose, crafted for 1990–1993 Mazda MX-5 Miata 1.6L (Engine to Pipe, Lower Hose). This OEM-quality hose is the exact fit you need for proper radiator connection, engineered to prevent leaks and maintain coolant pressure under street and track conditions. Parts Geek+1
Made from premium EPDM rubber and reinforced with synthetic-fiber knit, the 20661 resists heat, ozone, coolant chemicals, and vacuum-induced collapse—even during prolonged aggressive driving. Its pre-shaped design maintains routing integrity, preventing kinks and ensuring secure mounting on OEM brackets and pipes.
This molded hose meets SAE 20R4 Class D2 and DIN 73411 Class A standards (with tolerances), offering peace of mind with consistent performance across temperature extremes. Moreover, it’s a direct replacement for the factory lower hose—from the engine to the radiator pipe—designed for a precise, hassle-free fit.
Whether addressing a failed OEM hose on a high-mileage daily or upgrading before track events, the Gates 20661 hose delivers durability, precise fitment, and lasting reliability. Backed by Gates’ reputation for OEM-grade parts, you’re getting a component tailored for spirited Miata performance and peace of mind.
