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.

BMW 740i V8-4.4L - Brake System Inspection - Chicago, Illinois

Inspected my car and test drove it. Told me exactly what was wrong and showed me the problems. Seems to be very familiar with this type of BMW and knew about some of the problems I've had with it before I even told him. Very happy with his inspection and the advice he provided on how to get everything fixed and how to properly maintain this type of car.

BMW 740i V8-4.4L - Starter - Beaverton, Oregon

Andrew came out last week and troubleshot my car in the garage and said it was the starter motor. I had suspected it was the starter motor but wasn't quite sure so it was good to get a verification. I have to admit, I was kinda skeptical about this home mechanic thing so I was taking a wait and see attitude until after he came back for the repairs. Both times, Andrew showed up early..which is fine by me. Today, when he came back, he went straight to work installing the new starter motor and changed the oil. Car fired right up so I was happy and I've started it a few more times and it is working well and I don't see any oil leaking. If there was a half star option, I'd deduct 1/2 star. Andrew needs to carry some oil rag buckets or something since he put a bunch of oily rags next to the sidewalk and I went out to clean them up (my dad saw them on his way out and text me and I said, it can't be the mechanic) and had to dig up some dirt since the rags were leaking oil. I'm not sure why he thought placing them on the ground was a good idea but oily rags on the ground is never good especially when it's raining. Overall, I'm happy with the repairs and the experience and will definitely consider using the service again especially since I'm working from home and don't get into my normal shop anymore.

BMW 740i L6-3.0L Turbo - Trunk does not lock or open - Corona, California

Issue to get smog test pass because some leaking. He did fix it and got pass the smog test certicate. It is on BMW z3 2001 car. Seems little expensive but much cheaper than taking to dealer. Highly recommended
