Why are Coolant Flushes Recommended?

Overheating is the most common cause of vehicle breakdown and engine problems.

Servicing your cooling system will help maximize the performance of your vehicle’s heating and cooling systems. Just like engine oil, your vehicle’s antifreeze needs to be maintained by flushing it regularly which actually costs less than oil changes over the years.

Coolant will become contaminated and breakdown because of constant temperature changes. Dissimilar metals and the chemical reactions can make coolant acidic, discolored and murky. Your cooling system will slowly become filled with dirt and sediments which can damage the water pump and restrict coolant flow through your vehicle’s radiator and heater core. This can cause overheating or poor heater output.

Most manufacturers recommend servicing your cooling system every two years. Some have introduced extended life coolants to eliminate the need for flushing. John’s Auto Care as well as others in the service industry advise against this for several reasons. First, most people don’t drive their vehicles in optimum conditions as described in their owners manual. Second, it costs so little for a cooling system service compared to costly engine repairs. The old saying: an ounce of prevention is worth more than a pound of cure, says it best.
