When your car’s air conditioning stops working, it can make even a short drive uncomfortable—especially during the hot Kentucky summers we experience around Paducah and Murray. Your vehicle’s A/C system is made up of several components working together, including the compressor, condenser, refrigerant, and blower motor. If any one of these parts isn’t functioning properly, your system may stop producing cold air or may not work at all. Sometimes the issue is as simple as low refrigerant, but other times it can point to a worn component that needs professional attention. One of the most common reasons a car’s air conditioner stops blowing cold air is a refrigerant leak. Over time, seals and hoses can wear out, allowing refrigerant to slowly escape from the system. Without the proper refrigerant level, the compress ... read more

If you’ve ever seen steam rising from under a vehicle’s hood on the side of the road, there’s a good chance the radiator was involved. Your radiator is one of the most important components in your vehicle’s cooling system. Its job is simple but critical: it keeps your engine from overheating. At Harlan Automotive, we often explain the radiator as the part that protects your engine from damaging itself due to excessive heat. Your engine creates an incredible amount of heat every time you drive. Controlled explosions are happening thousands of times per minute, and without a way to regulate that heat, internal components would quickly fail. The radiator works by circulating coolant, also known as antifreeze, through the engine. As the coolant moves through, it absorbs excess heat and carries it away from critical components. That heated coolant then travels to the radiator, where it passes through thin metal tubes and cooling fins. As air flows across those fins ... read more

Why Is My Car Overheating? 3 Common Causes Drivers Should Know When your temperature gauge starts climbing or you see steam from under the hood, it’s not something to ignore. Engine overheating can quickly turn into expensive repairs if left unchecked. At Harlan Automotive, these are common reasons we see vehicles overheating. 1. Low Coolant or a Coolant Leak Your cooling system depends on antifreeze (coolant) to regulate engine temperature. If coolant is low due to a leaking hose, radiator, water pump, or reservoir, your engine won't be able to properly remove the heat. Warning signs: Sweet smell under the hood Colored fluid under your vehicle Temperature gauge running high Catching a coolant leak early can prevent major engine damage. 2. Faulty Thermostat The thermostat controls coolant flow through your engine. I ... read more
