The Magic of Engine Coolant: Why Boiling and Freezing Can Spell Trouble

Shawn Gilfillan • October 31, 2023

It is essential to maintain the right engine coolant levels to ensure your vehicle's engine operates smoothly. Engine coolant, also known as antifreeze, is a critical component that helps prevent engine overheating and freezing. However, many people are unaware of the potential dangers that can arise when engine coolant either boils or freezes. At Magic Lube and Rubber, our experienced technicians understand the importance of maintaining the proper coolant levels, and they use specialized tools such as a hydrometer to ensure your vehicle's health.

The Danger of Boiling Coolant

If your engine coolant boils, it can create problems for your vehicle. Engine coolant is designed to prevent your engine from overheating, and when it boils, it loses its ability to regulate temperature effectively. This can lead to engine damage, including cracked cylinder heads and blown head gaskets. An overheated engine is an expensive problem that could leave you stranded on the side of the road.

The Jeopardy of Freezing Coolant

On the flip side, freezing coolant can be equally problematic. When coolant freezes, it expands, which can lead to burst hoses, radiators, and even engine blocks. If you live in an area with cold winters, this can be a common issue if you don't have the proper antifreeze mixture. To prevent freezing, it's crucial to maintain the right coolant-to-water ratio, and this is where Magic Lube and Rubber's technicians come in.

The Magic Lube and Rubber Solution

Our skilled technicians use a hydrometer to check the coolant's specific gravity, which indicates the concentration of antifreeze in the coolant mixture. By taking a small sample of the coolant and measuring its specific gravity, they can determine if the mixture is too concentrated or too diluted. If it's too concentrated, it and under pressure could boil too quickly; if it's too diluted, it might freeze in cold temperatures. The technicians then adjust the mixture to ensure it's within the ideal range, usually around a 50/50 ratio of coolant to water, depending on your vehicle and the local climate.

Regular maintenance at Magic Lube and Rubber can help you avoid the headaches and expenses associated with boiling or freezing coolant. Our experts understand that the right coolant mixture is the key to a healthy engine, and they are equipped with the knowledge and tools to keep your vehicle running smoothly, no matter the weather conditions. So give us a call or schedule an appointment online today, a get some extra peace of mind heading into the colder temperatures ahead.

Engine coolant is a vital component for regulating your vehicle's temperature and ensuring its longevity. Avoid the dangers of boiling or freezing coolant by entrusting Magic Lube and Rubber's skilled technicians with the maintenance of your vehicle's cooling system. With a hydrometer in hand, they'll make sure your coolant mixture is just right, so you can enjoy worry-free driving in any season. Call us today!

Drive Belts & Pulleys: The Unsung Heroes Under Your Hood

April 9, 2025

When it comes to car maintenance, there is a lot that comes into play. It can almost be overwhelming at times. Focus on common wear items like the battery, brakes, and tires are usually at the top of the list for most, but there are other items that need attention as well. Drive belts and pulleys are some of these items. These small components help keep your car running smoothly, and after a while they do wear out and need replacement. Unfortunately, failure can lead to a breakdown on the side of the road and leave you needing a tow. So what are they and what do they do? Let’s find out. What Are Drive Belts and Pulleys? Think of drive belts as super strong rubber bands that transfer power from your car’s engine to help run other important components. The pulleys are similar to any other pulley; they are just metal wheels that help guide and control the belts movement. However, these pulleys are attached to other engine accessories, and when the belt spins the pulleys they provide power to these other accessories. Together, they keep essential parts of your car operating. Most modern cars use a serpentine belt, a long, continuous belt that is wrapped around multiple pulleys that power multiple systems. Older vehicles might have V-belts, which are shorter and typically run a single component at a time. What Do Drive Belts and Pulleys Power? Drive belts are made from durable rubber and reinforced materials, but they don’t last forever. Over time, they can crack, stretch, fray, glaze, or even snap. Pulleys have a lifespan as well. They are subject to corrosion and the bearings can go bad and even seize up completely. Without drive belts and pulleys, several key systems in your car wouldn’t function properly. Here’s what they keep running and what can happen if they fail. Alternator – Powers your car’s electrical system and keeps the battery charged. If the belt breaks, your battery will eventually die, leaving you with a car that won’t start or may die while you are driving. Water Pump – Circulates coolant to prevent your engine from overheating. A broken belt could lead to severe engine damage due to overheating. Power Steering Pump – Makes turning the steering wheel easier. If the belt slips or breaks, steering your car instantly becomes much harder, especially at low speeds. Air Conditioning Compressor – Helps keep your car cool on hot days. While not as critical as other components, losing A/C can be uncomfortable. Drive Belts and Pulley Maintenance Drive belts and pulleys don’t necessarily require maintenance, but they should be inspected regularly. In some cases, a bad pulley can cause the belt to slip or even pop off of the pulley completely. There are a few things to look for that may tell you it’s time for replacement. Check for Cracks, Fraying, or Glazing – Look for visible signs of wear on the belt. If you see cracks, missing ribs, fraying, or a shiny, glazed appearance, it’s time for a replacement. Listen for Strange Noises – A worn out belt or pulley may slip on the pulleys and cause a high-pitched squealing, chirping, or rattling noise when you start the car or turn the wheel. Watch for Performance Issues – If your battery warning light comes on, your power steering feels heavy, or your car starts overheating, a belt or pulley could be the culprit. Have Regular Inspections – Most belts last between 50,000 to 100,000 miles, but checking them during routine maintenance can prevent unexpected failures. Replace Before It Fails – A worn belt may still work, but it could snap at any moment. Replacing it early saves you from the headache of a sudden breakdown. Final Thoughts Drive belts and pulleys may not be the most glamorous parts of your car, but they play an essential role in keeping your car running smoothly. Keeping them in good condition helps ensure your car stays reliable and safe. At Automotive Magic , we offer a bumper to bumper vehicle health inspection that includes checking belts and pulleys for wear. Our inspections are sent to you with photos, videos, and descriptions explaining any issues we find with your vehicle and their severity to keep you on the road with confidence. Stop by today or schedule an appointment, and let’s make sure your car is running at its best!
