Where does the coolant go after a flush?
As air flows over the radiator it cools the coolant and then the cycle continues. Typically the coolant runs into your engine via the lower radiator hose and then gets pumped back into the radiator via the upper radiator hose.

Do you flush your Radiator with antifreeze?
While car owners will check the level of antifreeze in their coolant reservoir, not everyone will perform a timely and correct radiator flush. Your vehicle’s radiator may not be a part of its engine, but it is a critical component in your ride’s cooling system. Neglecting your truck’s cooling system can ultimately lead to issues in your engine.
When to change the coolant in your Radiator?
After 4 to 6 years or after driving 40,000 to 60,000 mi (64,000 to 97,000 km), it’s recommended that you change the coolant in your radiator to keep your engine running well. Changing the coolant requires draining the existing fluids and flushing the system before you add a new antifreeze solution.
What do you need to know about a radiator flush?
A radiator flush (or coolant flush) consists of four steps: Draining the existing coolant from your vehicle’s radiator. Adding new coolant and conditioner to the radiator. The new mixture then circulates through the vehicle’s cooling system, loosening any sediment and rust that has built up in the radiator channel.
How do you flush coolant out of a radiator?
Open the drain, and allow all the coolant to drain into the container until it stops flowing out. Then close the radiator petcock or drain. Pour the radiator flush product into the radiator. Fill the radiator with water from your garden hose until it’s about one inch below the radiator neck. Follow the product directions.
Where does the coolant go in a radiator?
Open the radiator fill cap, usually on top of the radiator. If your vehicle has a plastic tank or reservoir for coolant, open that cap too. Consult the vehicle owner’s manual for the location of the radiator petcock, or drain, and position the container on the ground under that drain, so it’s ready to capture the escaping antifreeze.
When to flush the coolant system in a new car?
If you have a pretty new car, or you’ve been punctual with your routine maintenance schedule, your car should be just fine with this. If the manufacturer recommends flushing your cooling system at certain intervals, then definitely do it. Make sure that any instructions that the manufacturer specifies for this procedure are followed.
Can a radiator be flushed if it is leaking coolant?
It must be noted, however, that if your vehicle is leaking coolant or if you find that the engine is overheating, then a radiator flush is not recommended. The cooling system cannot be flushed if it is not functioning properly in the first place. Note: Always start with a cold vehicle when flushing a cooling system.
How often should you flush your car’s cooling system?
Sometimes there may still be air left in the system and it will find its way to the top of the radiator overnight. Simply top off the coolant, if needed, and you are good to go. Car manufacturers recommend that you flush the radiator at least every other year or every 40,000 to 60,000 miles.
When to drain and refill a fully sealed cooling system?
Coolant which has expanded as the system warms up passes down the tube into this tank, and is drawn back into the radiator when it has cooled. The system is supposed to be maintenance-free, and is drained only when a hose or the coolant is due for replacement.
What happens when you get a coolant flush?
When you get a coolant flush, it is also common to receive an inspection of your entire cooling system including the thermostat, radiator and all hoses and belts. This is beneficial because it checks for leaks and other potential problems. Getting a coolant flush will prevent the old anti-freeze from becoming acidic.

What happens when you change the coolant in a car?
The coolant can become more acidic over time and lose its rust-inhibiting properties, causing corrosion. Corrosion can damage the radiator, water pump, thermostat, radiator cap, hoses and other parts of the cooling system, as well as to the vehicle heater system. And that can cause a car engine to overheat.
