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 K1500 V8-5.7L - Service Battery/cables - Camas, Washington

Andrew arrived on time and listened to the issue going on with my truck. He immediately went about confirming my suspicions of the battery cables being corroded or damaged by checking the voltage at the battery and then at the starter. He thoroughly cleaned the terminal ends which prompted the engine to engage, but not quite start. He then suggested I pressurize the fuel pump and showed me what to do, which then allowed the vehicle to start right away. He then performed a further check of the engine fluids and made recommendations of what to address next. He was very easy going, polite, professional and competent in his work. I would definitely recommend him.

GMC K1500 V8-5.7L - Car is not starting - Cleveland, Ohio

Matthew identified my problem quickly, yet took the time to check all the involved circuitry for possible contributing factors to the issue at hand. The immediate issue was solved and I was able to use my vehicle for a scheduled appointment. Thanks, Matt! p.s. less expensive than a tow to my usual service provider right around the corner. Very pleased.
