Many people get confused with the difference between a "cooling system flush" and a "drain/refill". The truth of the matter is that there is a big difference. While a drain and refill is fairly straight forward and generally not difficult, a flush is much more effective and requires special equipment.
A drain and refill generally only includes draining the radiator and reservoir then refilling it with new fluid. This is a fairly easy job for most people. Just make sure you have a plan for getting rid of the old fluid as you cannot just pour it down the drain or onto the street. Keep in mind that a coolant flush is the only way to properly remove contaminates. Whether it is contaminated with rust, debris or transmission fluid ( a common fluid that leaks into the radiator), the only way to properly clean it is with a flush.

How Often Should It Be Done?It is generally recommended that a coolant service be performed every 30,000 miles or three years, whichever comes first. If you are unsure whether or not your vehicle needs a coolant flush, take it to a certified mechanic, they can accurately test coolant to identify if the coolant is dirty and corrosive. It’s also a good idea to have it checked by a trained technician each oil change or inspection interval.
What Is Involved With A Cooling System Flush?A safe and effective cleaner in used to remove harmful sludge and deposits from the cooling system. The old coolant and contaminates are then removed. The cooling system is then filled with new coolant with conditioner to give the cooling system components the best corrosion and freeze protection possible.
Five Signs That You May Need A Cooling System Flush:
- Temperature gauge fluctuates between normal and hot
- Antifreeze/coolant pooling under the vehicle
- Grinding sounds coming from the engine area
- Visible rust and/or scaling in the antifreeze/coolant
- Steam and/or hot maple syrup-like smell coming from under the hood
