How the Cooling System Works
The cooing system circulates coolant through the engine. As it flows through the engine, it absorbs heat. The coolant flows into the radiant where the heat goes into the air. The coolant flows back to the engine to repeat the process over and over. The coolant also helps the engine warm up quickly by pushing the cold liquid from the radiator to the engine.
What Does the Cooling System Service Include?
Cooling system service begins with an inspection of each of the components, such as belts and hoses. A diagnostic is performed before any repairs are made, so we can see how well your cooling system is working. The diagnostic will tell us if you are having problems with cooling system components like your radiator, a failing thermostat, low coolant levels, or some other component. In step-by-step order you can expect the following when you bring your vehicle in for service:
- Inspection of radiator, thermostat, water pump, head gasket, heater core, control valve, hoses, belts, and fans.
- Check for worn elements, cracks, and leaks.
- Check coolant volume and pressure conditions.
- Flush and dispose of old coolant fluid.
- Install replacement parts as needed.
- Refill the coolant system with coolant fluid.
How Often Should I Get a Coolant System Flush?
There isn’t an expiration date for antifreeze, but over time the fluid will begin to deteriorate and become less effective. Your owner’s manual will usually provide a recommended schedule of mileage intervals to change your coolant, but it can range from 30,000-120,000 miles. Since there is a lot of variation between makes and models, the best practice is to check your manual.
If you start to notice any of the following signs, you may want to schedule an appointment with Mark Christopher Auto Center to have your coolant system checked out.
Signs That a Coolant Flush May Be Needed
- Engine overheats: If you see steam coming out from under your hood frequently, you probably need new engine coolant (which is antifreeze and water in a 50-50 ratio).
- High temperatures: If your temperature gauge shows high temps, you probably need service.
- Sweet, maple syrup smell: You might think someone’s cooking breakfast nearby, but it’s your cooling system. The smell is caused by antifreeze being burned up by the engine.
- Fluid leaks: This fluid is usually green or orange, but other colors are possible. Look for puddles beneath your vehicle.
What Happens If Your Vehicle Doesn’t Have Enough Coolant?
You may notice a low coolant light on the dashboard. If this light stays lit, it means you need to add coolant to your system. There could be a leak, so it’s important to get the system checked out by our service team. If your vehicle continues to run on low coolant, it could cause major issues, including:
-
The engine may overheat.
-
The vehicle could shut down while you’re driving.
-
The vehicle may blow a head gasket.
-
The engine could fail, requiring it to be replaced.
Failing to address low coolant could result in expensive repairs or the need to replace the vehicle.
The Difference Between Antifreeze and Coolant
Antifreeze is the substance that prevents the engine from freezing up in cold weather or overheating during the summer. Coolant is a mixture of antifreeze and water, usually a 50/50 mixture. You should never put straight water into the cooling system because it will freeze in cold weather.
What to Do If Your Low Coolant Light Comes On
If the low coolant light comes on while you’re driving, you should monitor the temperature gauge. As long as it stays where it normally is, you can continue to drive safely until you reach your destination or a safe place to stop the vehicle. Check the coolant level, being careful to wait for the engine to cool off before removing the cap on the reservoir.
You can add coolant to the max fill line and continue on your way. However, you’ll want to bring your vehicle in for service so our team can check for any leaks.
If the temperature gauge shows that the vehicle is overheating, you should pull over to the side of the road immediately and shut off the engine. Many newer models have a safety sensor that shuts down the engine to prevent damage. Once the engine cools, you can fill it with coolant to drive to a service center. If the leak is too drastic and the coolant drains out quickly, you’ll need to have your vehicle towed for service.
