Mercury Coolant Reservoir Cap also maintains the cooling system at the correct amount of pressure to ensure that your car is maintained at a healthy temperature. Over the decades Mercury developed a reputation of midsize that was a smooth-riding vehicle with sharp style. Mercury models were named after the Roman messenger, and they had silent cabins, elegant suspension, and controls that were user friendly. Drivers also preferred the way the brand combined an aggressive V8 with a stable steering to make their daily commute and highway adventures consistent. Large trunks and cushion seats were also applied to make the brand stand out. Although the company has maintained a balance between comfort and value up to the time the production ceased in 2011, Mercury has always focused on less road noise and comfortable seating which made long journeys easy. The outcome perfectly corresponds to the philosophy of simple reliability of Mercury engineering. This is a small yet very tough Coolant Reservoir Cap which closes the expansion tank, provides pressure, prevents leaks, and allows the heated coolant to safely expand. Installation of a Coolant Reservoir Cap requires that the ground should be level before the engine is fully cool, cover the old cap, and twist the new cap slowly to release the pressure and it should be removed. Wipe off the filler neck, fit up the new Coolant Reservoir Cap, size-wise, to the old, test the rubber seal and then press down and twist until it clips. Fill coolant to the mark and start the engine, inspecting it after a few minutes to see whether there are any leaks or warning lights, close the hood, watch the gauge during your next drive, and reexamine coolant once the engine has cooled down.
