As the summer heat intensifies across Missouri, it's crucial to raise awareness about the life-threatening risks associated with high temperatures, particularly when it comes to leaving pets or people in hot cars. The scorching heatwaves can turn vehicles into ovens within minutes, posing severe dangers to anyone left inside, including pets. Understanding the Risks Missouri, known for its humid subtropical climate, experiences significant temperature spikes during the summer months. In such conditions, the interior of a car can reach lethal temperatures rapidly, even if parked in the shade or with windows slightly open. According to the American Veterinary Medical Association (AVMA), on an 85°F day, for instance, the temperature inside a car can soar to 102°F within just 10 minutes, and exceed 120°F within half an hour. These conditions can quickly lead to heatstroke and death in both animals and humans. The Impact on Pets Pets, esp ... read more

What is Coolant? Coolant, also known as antifreeze, is a specially formulated liquid that circulates through your car's engine and cooling system to regulate its temperature. It's typically a mixture of water and ethylene glycol or propylene glycol, along with additives that enhance its performance and longevity. How Does Coolant Work? The primary function of coolant is to absorb heat generated by the engine and dissipate it through the radiator and into the surrounding air. As your engine burns fuel to power the car, it produces an immense amount of heat. Without proper cooling, this heat can build up rapidly, leading to engine overheating and potential damage. Coolant circulates through the engine block, absorbing heat, and then travels to the radiator where it releases that heat to the atmosphere. This process helps maintain the engine's optimal operating temperature, ensuring efficient combustion and overall performance of your vehi ... read more

The History of the Hood Latch The humble hood latch, often overlooked, plays a crucial role in vehicle safety and accessibility. Let's take a drive through history to understand how this small but vital component has evolved. Early Beginnings In the early days of automobiles, around the late 19th and early 20th centuries, hoods were simple coverings for the engine, held in place by leather straps or basic metal hooks. These primitive solutions were sufficient for the relatively slow speeds and simpler mechanics of early cars. The Rise of Modern Mechanisms As cars became faster and more complex, so did the need for secure and reliable hood latching systems. By the 1920s and 1930s, manufacturers began to introduce more sophisticated latch systems. These early mechanisms often involved simple levers and catches, allowing easier access to the engine while providing better security. Safety Innovations The mid-20th century saw sig ... read more

As summer temperatures rise, a functioning air conditioning (A/C) system in your car becomes crucial for comfort and safety. When your A/C starts blowing warm air, the natural inclination might be to simply add more Freon (refrigerant) to the system. However, this approach is often misguided and can lead to more significant problems down the road. Proper diagnosis and professional repair are essential for ensuring your car's A/C operates efficiently. At Hillside Auto Repair, we understand the intricacies of automotive A/C systems and are committed to providing top-notch maintenance and repair services backed by a 3-year/36,000-mile warranty on parts and labor. The Misconception: Just Add More Freon Freon, or refrigerant, is a critical component of your car's A/C system. It absorbs heat from the cabin and releases it outside, thus cooling the interior. When the A/C isn't working properly, it might seem like a low refrigerant level is the culprit. While thi ... read more

As responsible vehicle owners, staying attuned to the health of our cars is paramount. Among the critical components that demand our attention, the timing belt stands as a silent sentinel, orchestrating the synchronized movements of the engine's internal components. However, with time and wear, this essential part can deteriorate, potentially leading to catastrophic engine failure if not replaced promptly. In this comprehensive guide, we explore the warning signs of an aging timing belt, emphasizing the importance of proactive maintenance to avoid costly repairs and downtime. Understanding the Timing Belt's Role The timing belt, often overshadowed by more conspicuous parts like engines and brakes, plays a pivotal role in ensuring the smooth operation of your vehicle's engine. It synchronizes the rotation of the camshaft and crankshaft, ensuring that valves open and close at precisely the right times, coordinating with the pistons. This precise timing is c ... read more
