It is important to flush the radiator in your vehicle every few years to remove any debris or corrosion that may have accumulated. This will also help to ensure that the new antifreeze you add will be effective.

What causes the radiator not to circulate water?

If your car’s radiator isn’t working properly, it could be due to a bad water pump or thermostat.

4. Water Pump Rust and Corrosion: Over time, the water pump can rust and corrode, which can lead to failure.

5. Steam comes out from under your hood: If you notice steam coming from under your hood, it could be a sign that the water pump is not functioning properly and needs to be replaced.
