flush cooling system?, how to do it properly? Options

how do you properly flush the cooling system of a car?

I know the basics like hook up a garden hose and run water through the system as the engine is runing and heater on to help remove all the rust and containaments in there.

But what do you do with all that radiator fluid? You can't just let that drain into the storm drains.


And your not suppose to get hard water into the cooling system, that is why distilled water is needed. And flushing the cooling with gallons and gallons of distilled water will be very costly....

What about those chemicals you can buy?

What is the best way to do it? To be honest i dont trust those jiffy lube shops to flush my car, they probably wont use distilled water...

I actually work at jiffy lube, and we do the same as any dealership when it comes to flushing a coolant system. Our store is a stand up shop and we do everything by the book, i cant say the same for others stores tho.

the main reason i ask this question is because people spend money on distilled water to hope that there will not be any funk chemical that will cause the engine to rust, corroide or oxidize. And using toyota red coolent is proven to help keep metals from oxidizing and what not, But that only holds true if there is nothing else in the coolant. If your water is treated like most cities, there will be clorine, calcium, salt and other junk that will be in the water. So why bother spending extra money on toyota coolant when you can not get a complete clean cooling system?

No matter how you flush your system you will have unknown chemicals in there.

I personally flush many cooling systems my self and know the steps on how to do it. But I can't seem to find a "clean" way to do it.

Does your shop use tap water ( or water from the cities water lines) to flush the coolant systems?
