Procedures for Flushing a Radiator

A radiator flush can prevent engine problems down the road.

The life of your radiator can be lessened if you continue to allow rust and other dangerous residue to form within it. A radiator flush is when you drain, and replenish, the vehicle cooling system. Having knowledge of the correct procedures for flushing a radiator is vital to vehicle maintenance.

Time Frame

Your engine depends on a clean radiator to keep it properly cooled at all times. However, a radiator flush can be done on a less-frequent basis than an oil change. By having it flushed about once every 24 months, you are taking steps to keep the radiator and motor running smoothly.

Cost

The cost of flushing a radiator can vary from one auto shop to the next. Be prepared to pay as much as $150 for this service. Variables, such as vehicle type, model and year could play a part in determining price.

Procedures

The steps used in flushing a radiator are fairly simple and usually completed by the auto shop in under 20 minutes. During the process, older fluid is drained from your auto cooling system and replaced with new coolant, as well as an additive, which stops rust from rebuilding in your radiator.
