How to Diagnose Your Car’s Overheating Engine

If your car engine is overheating on a regular basis, it is time to stop driving, and start figuring out what’s causing the problem. It is important to address an overheating engine issue as soon possible; because the longer your engine experiences these issues, the more damage they will cause overtime. Worst of all, these damages will lead to costly engine repairs or full-on motor replacement. You can easily avoid these financial woes by simply addressing an engine problem when it becomes apparent to you. This can literally save you thousands of dollars.

Start by learning the most common causes for overheating motors, and then take some time to think about your driving habits. From there, you can make the necessary adjustments to get your car safely back on the road. Continue reading to do just that!

Top 3 Causes for Overheating Engines

❶ No Coolant

This is the number one cause for an engine that has begun to overheat. Always be sure to keep a spare bottle of coolant, also known as radiator fluid, in your trunk. If your vehicle gets low on a particularly long road trip or hot day, you can top off your radiator with more coolant. If more coolant works at first, but later the engine overheats again, you could have a coolant leak. Although more fluid solves the immediate problem, it is a sign that your vehicle probably needs some other types of fluid refills and flushes, including brake fluid, motor oil, windshield wiper fluid, transmission fluid, and more.

❷ Defective Coolant Fan

Sometimes you have enough coolant, but the fan is not working properly. When the coolant fan is not running, it will not cool down the coolant running through the radiator and engine like it is designed to do. This is generally caused by a faulty fan motor, but can also be caused by a bad radiator switch. If your car engine begins to overheat, you can lift your hood and take a look at your coolant fan to see if it is running or not. They are usually located right on or near the radiator.

❸ Broken Fan Belt

Like your coolant fan, your engine’s fan belt plays a major role in controlling temperature. It is one of the most common causes of a reoccurring overheating engine. The worst part about a broken fan belt is that it is often a first indication of other engine malfunctions and needed engine repairs. Most people can tell they have a broken fan belt by simply looking at their engine from under the hood.

Monitor Your Driving

To better figure out what’s causing the overheating, think about the type of driving you are doing when it occurs. Is your car engine overheating at stoplights or on the highways at high speeds? This information can give you clues as to why your car overheats.  If the vehicle is overheating during an idle or stopped position, this could point to the electric cooling fan motor. This component is located near the radiator. To check for faultiness, run the vehicle’s air conditioner and listen for the fan to start. If the fan doesn’t turn on, it may be from a faulty sensor or the fan in general. If your car is overheating at high speeds, it could be anything from a kinked radiator hose to a defective thermostat.
