We all know that our vehicles require regular maintenance to keep it running safely and reliably for a long time. Most people change their oil at some regular interval, which is one of the most important and cost-effective things you can do to make sure your car doesn’t take an early trip to the scrap yard. Also high on that list is to change the transmission fluid at the factory recommended intervals, but many of us don’t think about replacing our vehicle’s coolant if the car isn’t leaking or overheating.
What Is a Cooling System Flush?
Is it really necessary to change your vehicle’s coolant? It’s always best to follow the manufacturer’s recommendations for maintenance, so why do most automobile manufacturers recommend replacing your vehicle’s coolant periodically? Can antifreeze really go bad or wear out?
What is Coolant and What Does it Do?
To know if you need a coolant flush it’s important to understand what antifreeze, or engine coolant is, as well as what it does. The internal combustion engine could also be called a heat engine because it uses heat to cause gases to expand and uses the engine’s pistons to gather mechanical work from these expanding gases. Due to the temperatures present in an internal combustion engine, there will always be left over heat after each cycle. This excess heat needs to be removed to keep your engine at a constant temperature where it is able to continue working. The more quickly this excess heat can be removed, the more efficient the engine will be. The original internal combustion engines were air cooled, but water cooled engines were designed to take advantage of this principle.
- Heat transfer
- Corrosion inhibitor
What Does Coolant Do?
The main purpose of the coolant in your engine is to remove the excess heat through the radiator. Engine coolant is also called antifreeze because chemicals are added to keep it from freezing in cold climates so you can continue to operate your vehicle. The engine coolant is circulated through your engine block, radiator and heater core by the water pump. The water pump spins near the same RPM as your engine, so its bearings need to be cooled and lubricated. The antifreeze in your vehicle therefore is also a lubricant for the water pump. Lastly, it’s important for your cooling system to remain clean, even on the inside to promote good heat transfer so your coolant also is a corrosion inhibitor for the various types of materials it comes in contact with.
Why is it important to flush coolant?
The main reason to regularly change your antifreeze is to protect your engine from internal corrosion. Antifreeze contains different chemicals to maintain the pH levels and to keep the various materials from corroding. Over time, these chemicals are depleted or precipitate and will no longer protect your engine and cooling system from corrosion. Over time, this can lead to costly leaks and component failures.
Replacing your vehicle’s coolant is the best way to prevent future cooling system problems. Every time you replace the coolant, it is best to perform a cooling system flush as well. This will ensure that any depleted antifreeze, precipitants or corrosion products are completely removed from your vehicle’s cooling system. With the old antifreeze removed the new antifreeze will be able to better resist corrosion and with the precipitants and corrosion products removed, heat transfer will be restored to its maximum.
How do you flush a coolant system?
