Why Are Coolant Flushes So Important?
The cooling system is one of the most important systems in any vehicle, however, they tend to be one of the most overlooked and neglected when it comes to regular service. Engines operate at intensely high temperatures; the cooling system works to keep these temperatures at a moderate level, so the engine doesn’t overheat. Excessive heat can cause neighboring parts to fail and irreversible engine damage, so a properly working cooling system is vital.
How Does the Cooling System Work?
The cooling system essentially works by constantly circulating coolant (also known as anti-freeze) through the engine block. As the coolant makes its way through the channels of the engine, it absorbs and pulls away excess heat. After leaving the engine, the heated coolant enters the radiator, where it’s cooled by the air entering the radiator grill. The coolant is then recirculated to the engine, where the cycle continues.
Coolant, like other types of automotive fluids, does degrade over time. Older fluid can cause acid buildup in the cooling system or become contaminated; when this happens, its resistance to boiling and freezing becomes significantly reduced. You may find your car is running hotter than normal or your engine has difficulty starting in cold temperatures. If left too long, your coolant will lose all protective properties and your engine will be at greater risk of overheating and becoming severely damaged.
Four Reasons to Schedule Regular Coolant Flushes
The cooling system needs regular maintenance to perform its best. Coolant flushes involve removing the old coolant and any chemical buildup (like dirt, rust, or sludge) in the system. Then, the system is refilled with new coolant. Here’s a closer look at why coolant flushes are so beneficial:
Removes rust and other deposits from the cooling system
As you drive, debris will naturally collect in the cooling system. Left too long, these deposits can damage the cooling system and engine.
Coolant contains additives to help keep the water pump lubricated
In many cars, the coolant helps keep the water pump lubricated, which helps extend its life. It also keeps parts from rusting or becoming clogged with rust and keeps the thermostat from sticking.
Aging coolant can turn acidic
Acidic coolant can cause a number of problems for your vehicle, including damage to rubber hoses, the water pump, and metal components in the engine block. Fresh coolant prevents these and other issues.
Coolant flushes allow us to inspect other parts and systems in your vehicle
During a coolant flush, we can also check the health of the radiator, thermostat, hoses, and coolant belts. If we spot any issues, we can handle them proactively.
As a general rule of thumb, it’s best to schedule a coolant flush every 30,000 miles or five years—whichever comes first. Your owner’s manual will have specific recommendations on the best interval for your model. We’re also happy to look the service intervals up for you! However, if you’ve noticed the temperature gauge climbing or full-blown overheating, it’s important to schedule an appointment as soon as possible. The quicker the issue is addressed, the more likely you can prevent potential engine damage.
