Gates 16-18 Mazda CX-3 4-Cyl. 2.0L Lower Molded Coolant Hose

This is the lower molded coolant hose from Gates, specifically made for the 2016 through 2018 Mazda CX-3 with the 2.0L 4-cylinder engine. This hose is a direct replacement for your original, carrying coolant from the radiator to the engine block to keep things at the right temperature.

Gates uses a strong, heat-resistant rubber compound for these hoses, designed to withstand the constant expansion and contraction from engine heat and pressure. The molded shape ensures it follows the factory routing precisely, making installation straightforward without any awkward bending or kinking that could restrict flow. This is important because a kinked hose can lead to overheating issues.

Replacing a coolant hose is a good idea if you see any cracks, swelling, or feel any mushiness when you squeeze the old one. It's a relatively simple job that can prevent a much bigger problem like a coolant leak and potential engine damage.
