What is a radiator flush?

A radiator flush is a maintenance procedure that removes old coolant, rust, debris, and other contaminants from your vehicle’s cooling system. It helps ensure your engine runs efficiently and prevents overheating.

Over time, sediment and debris build up inside the radiator, which can block coolant flow, cause overheating, and damage your engine. A flush cleans out these deposits, maintains proper coolant circulation, and extends the life of your radiator and engine.

Most manufacturers recommend a radiator flush every 30,000 miles or every 2-3 years, but this can vary depending on your vehicle type and driving conditions. Check your owner’s manual for specific recommendations.

  • Engine overheating
  • Dirty or rusty coolant
  • Coolant leaks
  • Unusual engine noises
  • Temperature gauge fluctuations

A professional radiator flush typically takes between 30 minutes to 1 hour, depending on the vehicle and the condition of the cooling system.

Neglecting radiator maintenance can lead to clogged cooling passages, overheating, engine damage, corrosion, and costly repairs. Regular flushing helps prevent these issues.

No. A coolant change involves draining and refilling the coolant, while a radiator flush thoroughly cleans the entire cooling system, removing contaminants before adding fresh coolant.
