1999 Ford Ranger Flush Radiator
Most automotive-repair facilities offer "power" radiator flushes for a moderate fee. The costs of going to a repair facility can add up quickly. However, with a few basic household and automotive tools you can flush your 1999 Ford Ranger's radiator in your back yard or garage and avoid the large fees the professionals charge. To avoid damage to the radiator and to the Ranger's engine, a radiator flush is recommended once per year at a minimum.
 Tools Used
|Large storage container|
|Garden hose with nozzle|
 Flush Radiator
- Place the Ford Ranger on automotive ramps and set the parking brake. Allow the engine to cool for 20 minutes to reduce the temperature of the radiator fluid inside of the radiator. This will prevent you from being burned by the fluid as it drains from the vehicle.
- Raise the engine bay hood and open the radiator-filler cap that is located on the top-center of the radiator. Removing the cap releases pressure inside the cooling system.
- Place a drain pan under the radiator drain that is located on the bottom of the radiator. Turn the drainage valve counterclockwise. Use pliers if needed. Allow all the fluid to drain into the pan.
- Place the drain pan under the lower radiator hose where the hose connects to the radiator. Pull the radiator-hose clamp loose with a pair of pliers and pull the hose off the radiator. Drain the contents of the hose into the drain pan.
- Empty the drain pan into a large storage container suitable for radiator fluid. Place the drain pan back under the radiator.
- Spray the inside of the radiator with a garden hose. An ordinary nozzle will suffice. Do not use a power washer. They have too much pressure and can damage the inner lining of the radiator. Continue to spray the inside of the radiator until the water that drains out is clear. Empty the drainage pan as needed. It is common to use several gallons of water during the cleaning process.
