Purpose of a Car’s Radiator

If you have caught yourself wondering how often should you flush your radiator, you probably wanted to know the function of the radiator to begin with. When your car is running, your radiator helps to keep the engine cool and prevent your car from overheating. But that is not all the radiator does.

In the winter weather, your radiator actually helps to make sure your engine does not freeze up from the cold. Radiators vary in size depending on vehicle and model, but regardless, the radiator has a crucial role in your car’s continued functioning. If you want to avoid being the car with a smoking engine or having to explain to your boss that your car will not start because it is too cold out, you should consider keeping your coolant fresh and flushed regularly.

What Is a Radiator Flush?

A radiator flush is where you run cleaner through your cooling system to eliminate all dirt, debris, rust, and other contaminants that get into your coolant system. With all of the metal parts in your car’s engine, rusting is inevitable. A radiator flush will help to ensure you keep your cooling system corrosion free so that it can continue running. After flushing the old and dirty coolant out and running the cleaner through, new antifreeze is put back into your system with the proper diluted amount of water. This keeps your coolant fresh and clean, making it different from simply adding more coolant to your engine.

Signs You Need a Radiator Flush

If you wonder how often should you flush your radiator, you probably want to know what to look for to begin with. Your car may already be overdue for a radiator flush without your knowledge. You can buy a pH litmus strip test from your local auto store and dip it into your radiator to see if you need a test. The color will correspond with the guide provided so that you know if the coolant is too acidic from the contaminants.

If you start smelling antifreeze often, this could be another sign you need a radiator flush. Or, if wondering how often should you flush your radiator, you notice it does not take much for your car to overheat. If you are always adding coolant or notice a leak under your car, you should get your radiator checked in case you need a flush.
