Top Reasons Cars From Used Car Dealerships Overheat During Summer

Summer is here. As beach trips, barbeques, and road trips fill our calendars, keeping our vehicles in optimal condition throughout the heat wave is essential. However, overheating is an all-too-common occurrence when the mercury rises. Let’s explore why cars overheat during summer and how to prevent this from happening to your vehicle.

Low Coolant Levels

One of the primary causes of car overheating during summer is low coolant levels. Coolant, also known as antifreeze, plays a significant role in regulating your vehicle’s temperature. It prevents overheating by transferring heat from the engine to the vehicle’s radiator.

To minimize the risk of overheating, check your coolant levels regularly. If you notice that the levels are low, change your coolant or perform a coolant flush. Also, ensure that you are using the appropriate coolant for your vehicle.

A Clogged Radiator

Another common cause of overheating is a clogged radiator. Over time, rust, debris, and other remnants can accumulate within the radiator. As a result, the radiator becomes less efficient at transferring heat from the engine to the surrounding air.

To clean a clogged radiator, you should consider performing a radiator flush. This procedure cleans the cooling system and helps remove unwanted build-up. If the problem persists, consider replacing the entire radiator.

Malfunctioning Thermostat

The thermostat is a crucial component of a car’s cooling system. When functioning correctly, it regulates the coolant flow between the engine and the radiator. If you buy a car from used car dealerships and the thermostat fails or malfunctions, it may not open as required, causing your vehicle to overheat.

Periodically check your car’s thermostat to ensure it is functioning correctly. Replace the thermostat if you notice any signs of failure.

A Broken or Leaking Water Pump

Your vehicle’s water pump is responsible for circulating coolant throughout the engine. If the pump is damaged or begins to leak, it can directly impact the coolant’s flow, leading to an overheating vehicle.

Regular water pump inspection allows you to detect any damage or leaks early on. If necessary, replace the entire water pump to prevent further complications.

Old or Damaged Belts and Hoses

Over time, belts and hoses can age or become damaged, affecting the cooling system’s efficiency. Cracked, frayed, or loose belts need immediate attention as they can break anytime. Additionally, damaged hoses may leak coolant and impair your car’s ability to maintain an optimal temperature.

Inspect the belts and hoses in your car regularly, and replace them as necessary.

An Inefficient Cooling Fan

A cooling fan comes into play when your car is idling or during stop-and-go traffic, helping to dissipate heat from the radiator. Overheating can occur if your car’s cooling fan fails or doesn’t function adequately.

Inspect and test the cooling fan regularly to ensure proper operation. Also, replace the fan if needed.

High Outdoor Temperatures

Lastly, high outdoor temperatures are a significant contributor to car overheating. When the temperature soars, it’s crucial to be aware of the extra stress it puts on your vehicle’s cooling system.

To help reduce stress on your car during hot days, park in shaded areas, use window shades to minimize heat buildup, and avoid running your vehicle’s AC at full blast for prolonged periods.

Takeaway

You can significantly reduce the risk of overheating by regularly inspecting your cooling system, monitoring coolant levels, and taking preventive measures during scorching days. Remember to consult a qualified mechanic if you have concerns about your car’s cooling system or suspect an overheating issue.
