The car radiator is the reservoir that contains water and antifreeze to keep the engine cool while you’re driving. Over time, the radiator can get clogged with dirt even though the cap is tightly closed. That’s because the contamination is coming from the inside—the engine. To avoid the consequent problems that arise from an overheated engine, vehicle manufacturers recommend a periodic radiator flush every two years of 30,000 miles, whichever comes first.

What is a radiator flush?

A radiator flush involves flushing 4 to 5 gallons of antifreeze through the cooling system. All the old antifreeze and contaminants will get pushed out. Unfortunately, if antifreeze is not drained properly, it can cause a lot of damage to the environment that eco-friendly car owners would want to prevent.

Antifreeze primarily contains ethylene glycol, which helps the antifreeze to remain liquid even during winter temperatures. Despite its sweet smell and taste, ethylene glycol is poisonous and can lead to health problems and even death. Thus, antifreeze is considered a hazardous waste and should never be discharged into waterways or on the ground because it can kill animals and contaminate groundwater.

Do you still need a radiator flush?

As bad as antifreeze may sound, it’s still necessary to have a radiator flush scheduled for your car as preventative maintenance. You wouldn’t want to create more headaches and spend more money if your car is not working properly. These are some problems you may encounter that should tell you that it’s definitely time for a radiator flush.

  • The car engine constantly overheats.
  • The engine freezes up during winter when car is parked.
  • The heater is blowing cold air.
  • Gunk is floating in the overflow tank or radiator.
  • The pH litmus test on the antifreeze shows a high acidity level.

Benefits of getting a radiator flush

  • Rust and scale deposits are flushed out of the radiator to prevent them from building up and leading to overheating or damage.
  • The water pump gets lubricated with the radiator flush fluid and this should prolong the life of the water pump.
  • The old and dirty antifreeze and all its contaminants are drained out of the system. The older the antifreeze is, the more it loses its anti-corrosive properties. So it’s a great preventive measure to keep your engine from rusting.
  • Lastly, a radiator flush that can cost from $30 to $100 depending on your vehicle is cheaper than replacing a damaged engine.

Where can you get a radiator flush?

A radiator flush is available at any oil change places. Or if you want to do it yourself, you can purchase a bottle of BlueDevil Radiator Flush online or an auto parts store. To be environmentally friendly, make sure to catch all the coolant in a drain pan. You can take it to a local coolant recycling facility or auto parts store for safe disposal.
