What is the cooling system flush all about?

Your cooling system is what keeps your car from overheating. It works by circulating a mixture of water and coolant through the engine. Over time the coolant mixture becomes contaminated with scale and rust, which can clog and damage the cooling system components. A cooling system flush essentially flushes out the entire system of contaminants and replaces the coolant mixture with fresh coolant and water.

Keep in mind:

Your mechanic will drain the fluid, clean the system with coolant cleaner, and use water to remove the remaining coolant. After cleaning the system, the mechanic will fill it up with new coolant. This process is effective and an approved industry method of flushing your vehicle’s cooling system.

How it's done:

  • Install flush chemical to radiator
  • Bring the car to operating temperature
  • Drain the old coolant
  • Close valve and refill with water
  • Repeat the process
  • Fill radiator with a 50/50 mixture of coolant and water
  • Check for leaks and fan operation

Our recommendation:

  • Some vehicles are equipped with a low coolant sensing system. Should this light come on, have your vehicle inspected for leaks or other possible causes for the low coolant level.

  • Follow the service maintenance schedule provided by the manufacturer to get the coolant replaced at regular intervals. In general, it is a good practice to change the coolant every 40,000-50,000 miles.

What are the common symptoms indicating you need to flush the cooling system?

  • Check Engine warning light is on
  • Low Coolant warning light is on
  • Engine is overheating

How important is this service?

A cooling system flush is an important part of preventative maintenance and helps to keep your car healthy and on the road.
