How to Flush the Radiator in a Mercury Villager
- 1). Park the Mercury Villager on a relatively level surface and engage the parking brake. Then, pop the hood and check the external temperature of the radiator. If the radiator is cool to the touch, proceed to the next step. If not, wait for the radiator to cool down before you continue.
- 2). Turn the radiator cap one turn to relieve any internal pressure. Allow a few seconds to pass, and then completely remove the radiator cap.
- 3). Put a bucket with a capacity of at least 2 gallons underneath the radiator and below the drain plug. The drain plug on the Mercury Villager is usually on the rear bottom of the radiator.
- 4). Open the drain plug and let the old coolant completely drain into the bucket. Once complete, pour the old coolant into a sealable container for proper disposal.
- 5). Close the drain plug and fill the radiator with distilled water. Then open the drain plus and let the water drain into the bucket. Repeat until the water runs debris free out the bottom of radiator. You can use tap water, but it may leave sediments behind that can damage the cooling system. It usually takes at least 3 gallons of distilled water to flush the radiator completely.
- 6). Replace the drain plug on the radiator and fill the radiator with fresh coolant. It takes about 3 gallons of coolant to fill a Mercury Villager's radiator.
- 7). Start the engine of the Mercury Villager and turn the heater to high. Allow the Villager to run like this until the cooling fan kicks on twice. Shut the engine off and check the coolant level. If the coolant level went down, add more coolant, and then put the radiator cap back on and close the hood.
