Should I flush or replace my radiator?
An underperforming radiator can dramatically shorten the life of your engine and leave you stranded by the side of the road. However the good news is that a problematic radiator don’t necessarily require replacing. Often a good flush is all that’s needed to restore its cooling performance.
What does it mean to flush the radiator?
A coolant flush is another name for radiator flush, a procedure to clean your vehicle’s cooling system of sediment and rust. The coolant keeps your engine from overheating while running, and from freezing in cold weather when it’s not running.
What happens when you do not change the coolant in a radiator?
Besides, when you do not change your coolant for a long time, it will lose anti-corrosion capacity. It can cause deterioration of some metals such as aluminum, copper and others from the engine. This corrosion can clog some passages in the water pump and radiator.
What happens if you flush coolant in your car?
With modern coolants, flushes likely help the operation of the cooling system and, in any case, do no harm. If enough corrosives build up in your coolant, your metal engine parts can degrade. If enough contaminants build up that your engine freezes, you can end up with irreparable engine damage.
Can a radiator be drained to get rid of antifreeze?
Simply draining the radiator may get rid of most of the old antifreeze but could leave some coolant and contaminants behind, which would then mix with and pollute your new antifreeze and cause overheating. You want a full flush, a forced removal of anything old so you can pave the way for new fluid.

What is the average cost to flush a radiator?
On average, most radiator flushes are going to cost anywhere from $50 to $155. Most mechanics will recommend that you get a radiator flush every 36,000 miles. For those who want to perform a radiator flush themselves, supplies should cost about $15 to $35, depending on the make and model of the car and the store where you purchase from.
How do you flush a radiator system?
Flush the radiator with tap water until the drainage runs clear. Repeat filling the radiator with 1 gallon (3.8 L) of tap water, running the car with the heat on, and draining it once it’s cooled. Once the water runs clear, flush the system one last time with distilled water.
