How Much Does a Radiator Flush Cost?

post E-mail post Post   Comments (33)

A key part of a car's cooling system, a radiator is a sophisticated reservoir device that holds a mixture of water and antifreeze fluid (also called coolant); the radiator keeps the engine from overheating and in many cases it also cools the automatic transmission fluid. Rust and other deposits can form inside the radiator, which needs to be clean to be cool. Flushing the radiator is intended to remove built-up debris and to replace contaminated fluid.

Typical costs:

  • Expect to pay $40-$200 to have a radiator flushed, depending on the age, make and model of the vehicle; the recommended type and amount of coolant needed; and whether the work is done by a standard tire, muffler, oil-and-lube or auto repair shop, or by a car dealership, which tend to be slightly more expensive. CostHelper readers report paying $54-$144 for a radiator flush at a standard shop, at an average cost of $99; and $70-$175 at a dealership, for an average cost of $109.
  • Do-it-yourself supplies can cost $10-$50, depending on what is included. For example, a radiator flush kit[1] with clamps and garden hose adapters can cost $1-$15; a bottle of radiator cleaner[2] can cost $3-$25 for a 16-34-ounce bottle; and it can cost $10-$30 a gallon for standard antifreeze/coolant (typically green or red) or $15-$40 a gallon for super-long-life antifreeze with a rust/corrosion inhibitor (this coolant is typically orange). CostHelper readers report do-it-yourself radiator flush costs of $13-$34, with an average of $21.

What should be included:
  • During a radiator flush, the original coolant is drained and replaced with a special coolant/detergent mixture and fresh water; this is then drained and replaced with a standard mixture of coolant and water. It can take 20-30 minutes to flush a radiator with a machine, or up to an hour or two without a machine, because the vehicle's engine and radiator have to cool, then run and cooled again. An Expert Village video illustrates flushing engine coolant[3] with a home garden hose and Castrol.com provides how-to instructions[4] .
  • The maintenance schedule in the vehicle owner's manual will indicate how often the cooling system should be flushed and refilled, and the recommended type of coolant to be used. However, the need for a radiator flush also depends on driving habits and conditions; in areas where winters are exceptionally cold or summers extremely hot, many vehicle owners schedule a radiator flush at the start of each season. As a general rule most auto experts recommend flushing a system that uses standard antifreeze (green or red) at least every 30,000 miles or two years, although some recommend doing this annually. Super-long-life antifreeze typically lasts about 100,000 miles or five years.
Discounts:
  • Many company websites offer discount coupons for various services. For example, Brakes Plus[5] , Firestone[6] , Goodyear[7] and Midas[8] periodically offer coupons worth $5-$25 off basic services, including a radiator flush.
Shopping for a radiator flush:
  • Radiator flushes can be performed by car dealerships; gas stations; oil-and-lube shops like Jiffy Lube[9] ; tire shops like Firestone[10] or Goodyear[11] ; muffler shops like Midas[12] ; repair shops or auto parts stores like Meineke[13] or Pep Boys[14] ; or independent repair shops.
  • The National Institute for Automotive Service Excellence[15] and the International Automotive Technicians Network[16] provide searchable directories of repair shops.
  • Consumer Reports lists tips for finding a good mechanic[17] . Check to see if there are any complaints filed with the Better Business Bureau[18] .

Ther eis a drain valve on the block just above the oil filter. Get to it by raising car and climbing under passenger door. Once I loosened that it drained all night. Like a car with prostate. Its older and I hear the valve can plug. 1.5 gallons. Then loosen lower hose at radiator and watch out, a half gallon gushes out. Put all back and add 2.1 gallons prestone. Not easy. but fun with a teeneager and it teaches him something.

Radiator Fluid Replacement
Amount: $89.99

Car Make: ToyotaCar Model: Rav4
Auto Shop: Valvoline
Went in for my basic oil change and was told I should get m radiator fluid replaced. Price was 89.99 and all I really went there for was the standard oil change. But agreed to the service as I had 148,112 miles and couldn't recall ever having it done before on the 13 year old car. I still wonder if I really needed it or if I got suckered into paying an extra $89.99 in a sales pitch (they seem to do that a lot at these places - always pushing more than the basic oil change every time I go, which is why I dread going in the first place.)Lesson: definitely need to check my owners manual before I agree to these things!

June 2012: I suspected a clog in a drain line and told them so, I don't even think they checked it. They said usually that issue is fixed with a coolant flush, getting any air pockets out of the lines. The car does sound much better now so hopefully that was the fix -- if so I didn't mind spending the $80 on it. Plus free shuttle and car wash!

Radiator Flush and a few other things...
Amount: $20.00
Posted by: js3 in Artesia, CA.Posted: November 28th, 2011 08:11PM
Car Make: FordCar Model: Crown Victoria
Auto Shop: DIY
I flush the radiator in the Crown Victoria every few years. The temperature in Southern California is mild all year round, but we do drive to Las Vegas six times a year and have passed through Baker when it was 115 degrees out.

Incidentally, every summer there are fresh spots of charred asphalt on the highway where a car has overheated and burned down to the ground, so it's an incentive to keep the cooling system in good shape.

Car is 18 years old and the thermostat, radiator cap, top and bottom radiator hoses are all original, so I pulled them and put in new ones. Also the water temperature sending unit was malfunctioning for a while, so I replaced that. The additional cost for the extra parts was another $77. I bought a lot of the parts through RockAuto on manufacturer closouts (Brand names, very cheap)

I use a yellow "Glazers" pencil and write the date/mileage of the repairs on the underside of the hood to keep track.

My wife brought in the car. They told her that the tires were bad. We bought 1 year ago. They mentioned that the battery was weak. We bought that 2 years ago. They mentioned that the other stuff will cost more. We brought in car before for Rotor and brake replacement. They screwed up and the brakes engraved into rotors. I don't think they replaced the rotors, just the brakes next time we brought in. Car still has issue. Never go back to John Elway Toyota. They will try to milk you for your money and they give bad service.

Went to Jiffy's Rip Off Joint for oil change. They coaxed me into changing the Transmission Oil, coolant and oil for $291. I foolishly accepted. They changed that all in 20 minutes ! Now reading all this, I am realizing that I got ripped off. I will never again do business with Jiffy's Lube again and do not recommend anyone
