An engine’s lifespan is severely dependant on a car’s cooling system. When a car overheats, the resulting damage is often severe enough to require an engine overhaul. It is important to make sure the cooling system is always in good working order. Taking a few preventative measures may increase the life of your engine significantly.

One of the most common causes of car problems and brakedowns is cooling system failure. A failure in the cooling system can cause severe engine damage. Problems can stem from low coolant levels, old coolant, or leaks. Fortunately, it’s easy to prevent problems by having your cooling system checked and maintenanced regularly. You should have your coolant flushed and refilled as often as your vehicle’s manufacturer recommends.  Intervals typically range from 2 to 3 years, depending on the type of coolant and vehicle.

Your coolant system is what keeps your car engine from overheating in the summer and from freezing in the winter. It works by coolant being pumped by the water pump through the engine into the radiator. The coolant takes heat away from the engine and dispels it through the radiator by airflow that comes through the grill of the car. If this system brakes down or isn’t maintained it can cause damage to your water pump. This damage over time will affect not only the coolant system but also your engine and engine’s performance as well.

Many people avoid routine maintenance because of the expected high cost. You can get regular maintenance done on your equipment for around $150/year. Don’t wait until your air conditioner won’t cool or your furnace won’t ignite before you call for service. At this point you’ll typically pay more because it’s an emergency call, and have to wait because it’s usually around the hottest or coolest day of the year. Having your heating & cooling system put on a yearly maintenance schedule will pay for itself in lower repair costs, less aggravation, and more efficient operation.

Remember, every time you bring your vehicle to DOW Auto Care, we will inspect the condition and level of your coolant, and top it up for free.

Remember also, it is very important to keep your engine well maintained, and a regular oil change is very important

A/C Repair FAQs
Q: How does a cooling system work?

Engine coolant runs through your entire cooling system to and from the radiator. The water pump is what moves the coolant through the system. The radiator uses cooler air to bring down the temperature of the coolant. This diagram offers a more detailed look at the process and shows all the parts involved.


Q: What is coolant?

Also known as antifreeze, coolant is the red or green liquid in your radiator and throughout your cooling system. Radiators are usually filled with a 50/50 mixture of coolant and water. It keeps the water in your radiator and engine from freezing in cold temperatures. It keeps the water from overheating in all temperatures. It helps to lubricate the components in the cooling system.


Q: What is a coolant flush?

A flush is different from a simple drain and refill because it replaces all of the old coolant, and flushes out sludge, rust, and dirt buildup. A drain and refill entails only draining and refilling the coolant in the radiator. Flushing the coolant in your vehicle's cooling system is a great way to help maintain a healthy engine.


Q: Why does my vehicle need coolant flush?

As coolant gets older, it begins to lose its protective properties and doesn't do its job as well as it used to. Sludge, dirt and rust can also buildup in the cooling system which can cause a blockage in a hose or line. Having fresh coolant and a clean system better protects and cools all components.


Q: How often does my vehicle need a coolant flush?

There are a number of factors that determine how often to have a coolant flush, including the size of the engine, the vehicle's mileage, the climate you drive in, the age of the current coolant, the type of coolant in your system, and the manufacturer's recommendation. Most vehicles require a coolant flush every 24,000 to 30,000 miles, or every 2 to 3 years, whichever comes first. Check your owner's manual to see what your vehicle’s manufacturer recommends
