Flushing a clogged vehicle radiator involves draining it, connecting it to a garden hose and forcing water through the pipes. The supplies you need to flush your radiator are an empty lidded container for the old anti-freeze, a piece of sturdy wire, a garden hose, clean rags, a glass jar and fresh anti-freeze. This procedure usually takes about an hour and must be performed on a cold radiator with the vehicle turned off.Continue Reading
Place the anti-freeze receptacle beneath the radiator and set the radiator temperature control to its hottest setting. Remove the radiator's pressure cap and drain plug so that the anti-freeze drains into the container. If the coolant does not emerge on its own, insert the wire into the drain hole and wiggle it around. Fasten the lid and set the container aside.
Some radiators have drain taps. If yours has one, open it.
Disconnect both radiator hoses and insert a garden hose into the top hole. Stuff clean rags around the hose to keep it in place.
Replace the pressure cap and turn on the water. Keep the water flowing until clear fluid emerges from the radiator. Stick a clear glass jar into the liquid stream, collect a small sample and hold it up to the light. If the water is cloudy or contains suspended sediment, dump it out and keep flushing the radiator. Retest the water until it is clear.
Turn off the water and remove the garden hose. Reconnect both radiator hoses and fill the radiator with anti-freeze according to the vehicle manufacturer's instructions.
Take the container of old anti-freeze to a hazardous waste dump or ask your mechanic to dispose of it according to local laws.
To remove and replace a vehicle's water pump, locate the water pump and radiator, perform a pressure test, and drain the radiator into an approved container. Remove the drive or serpentine belts, disconnect the hoses attached to the water pump, and loosen the bolts securing water pump in place to remove it. Clean the mounting area where the water pump meets the engine, install the new gasket and water pump, and reassemble the belts before filling the radiator with coolant.Full Answer >
Common engine cooling system problems include a faulty thermostat, air buildup in the system, radiator hose leakage and radiator leakage. Blockage of the cooling system passages due to accumulation of scale and a faulty water pump or radiator fan are other cooling system problems. Repairing the engine cooling system depends on the problem with the system.Full Answer >
