The radiator of your car is one of its most important parts and ensuring that it is in perfect working condition is imperative. It not only keeps your engine cool when it is running but is also responsible for keeping it from freezing during the cold winter months. The value of your radiator for your car is obvious, so making sure that your system functions perfectly with routine radiator flushes is important.

The first sign that indicates that your coolant must be drained and replaced is if it changes in color; if it tends toward brown or is cloudy, do not wait to proceed to the drain the radiator.

If periodic radiator flushes are not carried out, the antifreeze that can also lose its acidity in time, which means that the coolant’s ability to effectively protect your engine would also decrease. A flush that removes ineffective coolant and keeps it fresh will only serve to extend the life of your radiator and all of its related components.

Sediment can also build up over time, and if this is not addressed it could eventually lead to radiator failure and overheating. That means that you could end up being one of those unfortunate individuals that is stranded on the side of the road with smoke emanating from under the hood. A chemical reaction between the contaminated coolant and the internal metal surfaces of your radiator can cause problems for your entire cooling system, which could eventually become an untimely and costly headache.

The best way to determine when a radiator flush is needed is to check the instructions in your car owner's manual, like with most other car-maintenance tasks. But, in some cases, you might need to perform this task in shorter intervals than recommended. This depends on your driving habits, as well as what weather conditions you drive your car under. In general, you should perform a flush every five years or when you've reached 100,000 miles.

Aside from the recommended intervals, you should also keep in mind some of the potential signs and symptoms indicating your car might need a coolant flush, like visible rust, debris, or corrosion.

When you are looking at a used car, take a look at the color of the coolant; it is an indicator of its maintenance.
