How Much Does It Cost To Flush a Radiator

The process of flushing the radiator removes any unwanted, internal gunk and perhaps clogs while allowing the antifreeze to be replaced. Performing the flush should be done at regular intervals and doing so can help restore improved temperatures brought to the engine by the water pump, radiator and entire cooling system.

How Prices for Radiator Flushes Vary

Performing the flush is usually a straightforward process. And there is much agreement that it should be done within every two years. However, even though some antifreezes are formulated to last, for up to 150,000 mile protection - some experts say that it still should be flushed at 24 months or under. While others yet, for instance, certain car dealer service personnel, disute that it should not be done at all unless there are specific signs pointing otherwise. When the flush is being done, however it is normally a good idea to check the radiator interior, and upper and lower hoses - inspecting them for signs of wear and potential points of breakage before refilling the cooling system.
  • To flush the radiator, with everything included, costs an average of $50 to $180 including disposal of old antifreeze, but depends on if the service is being carried out by a dealer or a local repair station. Dealers as usual will lean towards the higher end amounts.

  • Doing yourself - will save you money as this can be done for under $40, depending on if you have a drain hose, a safe place for engine coolant disposal & clamps. Flush kits run only between $4 and $8 for a basic featured kit. With the cost for coolant roughly $14 to $18 per gallon for undiluted concentrate, depending on type and brand. Some systems with minor leaking may have stop leak added - Bars Radiator Leak Stop is priced at $5.39 for an 11 ounce bottle that conditions up to 4 gallons.

  • Testers for the antifreeze (colored-bead models) are around $3 to $4 and help test both before and after. Besides the onset of any expected deep freeze temperatures.

  • If the engine is running out of its normal temperature range, as told by a dash gauge, you might want to pull and test the engine thermostat.

Reducing Amounts Spent

The main way to save on flushing is to do yourself, but taking precautions cannot be overly emphasized since there is a distinct possibility of scalding and injury.

By replacing the hoses, you can prevent other expenses caused by their bursting.
