Every OEM Mercury part includes the manufacturer's warranty, easy returns, and super-fast delivery. So why wait? Shop now and get your vehicle back to peak condition.

Mercury Cooling Hose is a durable heat-resistant tube installed by running through the block, radiator, and core in the heater, the sole purpose of which is to keep the coolant flowing in order to cool the engine. Mercury was reputed to possess a balanced muscle and civility, and that spirit has persisted through each part of a service. Hydraulic bushings provide a smooth ride, but the brand did not compromise steel thickness; thereby, the Cooling Hose has additional fabric weave and UV blockers that shake off road salt. The bay itself has a Mercury hose that curves without any kinking due to internal spring wire, which forces the coolant to flow through tight turns and the rubber to remain pliable in frosty dawn mornings. The compounds that are resistant to ozone prevent cracks that allow the fans to spin peacefully since air pockets do not form. Every curved line is factory-length with authentic Mercury fit that makes changing it like putting on a glove, and reinforced ends bite clamps, preventing annoying drips that cause driveway disfigurement. High trust. Move directly to installation. Allow the car to rest until the temperature gauge decreases and unscrew the cap to release pressure to lower the coolant level below the level of the hose. Follow the Mercury routing path, snap a picture to use as a reference, loosen the two clamps, and untwist the old Cooling Hose. Wipe necks clean, match the diameter and curve, slide the new Cooling Hose in, clamp over it, fit it in, and screw each screw tight. Squeeze the upper line to bleed the air, start the motor, watch for a steady flow, and check the clamp tension when the hose is hot to drive away knowing temperatures remain constant.
