Cooling System Flush Service

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.

GMC R3500 - Brake System Inspection - Newark, New Jersey
Pretty good. My inspection for my brakes went very quick, (a little too quick.) Not the most thorough inspection. However, Tomas came to the same conclusion that I had already suspected and the problem is now "dually" analyzed. 15 minutes, and I'm good. Tomas was quite knowledgeable and polite. He came with the proper tools and equipment to say the least and was promptly on time for the booked appointment. I would consider requesting Tomas again for similar work. Thanks again to Tomas and the team at YourMechanic for helping out.

Abdul was terrific. Came to my house while it was raining. Had a good solution quickly to continue to work while it was raining, as I thought we would have to postpone. Great job!!!

GMC Acadia - Cooling System Flush - Los Lunas, New Mexico
I booked an appt. to have the cooing system in my 2012 GMC Acadia flushed and have the thermostat replaced. The day before the appt. I sent Augustine a message, letting him know the issue I was experiencing with my vehicle. Augustine replied within a few minutes, he is very knowledgable and took the time to explain the possible causes of my car running hot. He arrived on time and after inspecting my car he let me know that the cost would be cheaper than I was quoted. He informed me that The radiator didn’t need to be flushed and I would only be charged for the work he did . I would highly recommend Augustine to anyone who asked me if i knew of a trustworthy mechanic!

GMC C1500 - Cooling System Flush - Las Vegas, Nevada
Paul was waiting for me at my house as soon as I got home from work. As soon as Paul was waitng for me at my home when I left work. I parked my truck and he jumped up and got right into flushing my cooling system! Had heat within 25 minutes! He is very knowledgeable about the job he is a pleasure to talk to. He described what he was doing step-by-step and helped me understand what was going on. I would definitely want Paul for any future issues I might have with our vehicles.
