While it may not be difficult to locate replacement parts for Mercury vehicles, these days the necessity for nothing but the absolute best are required to repair your car or truck. The vehicle in your driveway is head and shoulders above the rest when it comes to all the vehicles these days. It's not a regular occurrence that you realize that you have to buy a replacement Heater Hose to repair your automobile. Your Mercury dealership isn't the only place to find trusted repair parts to fix your Marquis.

Don't go too long without fixing your Heater Hose... here's why.

Before cars and trucks were built with the ability to cool their interiors, they had the ability to heat them. The engine of your Mercury Marquis circulates liquid coolant throughout the block to absorb heat, and sends this liquid to the heater core (a small radiator) through a heater supply hose when you want to warm your vehicle's cabin. Mercury Marquis heater hoses help cool the engine by supplying an alternative path for hot coolant to travel. The return heater hose will usually drop the coolant back into the water pump or a by-pass housing in your engine so it can go back to the radiator.
