Is your car overheating without warning? Do you need to determine the cause of this issue and how serious it may be? There are several common reasons why cars overheat, leading to a quick fix or further repairs. Your Mazda dealer can assess your vehicle and determine how to prevent your car from overheating and resolve issues related to its cause.

1. Worn Radiator Hose

If you own a pre-owned car with an older set of hoses, they may wear over time, leading to poor performance, leaks, and overheating. If you notice coolant dripping on the ground and this fluid grows in size, this can mean you’ll need to repair or replace the radiator hose. It’s also important to check the metal circles and hose clamps to ensure they are in good condition or require replacement.

2. Overheated Engine

Engines are equipped to handle temperatures to a certain level, though if they overheat or run at a high temperature for extended periods, this will cause issues. You may notice warped or melted cranks, pistons, metal, and other parts that can lead to severe damage. When consistent overheating occurs, this will not only damage your engine it may impact other parts of your car, which can lead to expensive repairs.

3. Thermostat is Stuck Open or Closed

Your car’s thermostat determines how much coolant flows to and from the radiator to the engine. When this mechanism becomes stuck in either a closed or open position, this may cause excessive coolant, or not enough of this substance, to flow from one system to the other. This issue can quickly lead to overheating and severe damage. If you notice your thermostat isn’t working correctly, you may need to repair or replace it to prevent possible damage. 

4. Broken Radiator Fan

Radiator fans are essential in regulating temperature in your car and help cool your vehicle’s antifreeze. If this fan stops working, your car will quickly overheat, and the fluid won’t effectively cool as needed. If you notice your radiator fan is functioning poorly or stops altogether, it’s essential to consult with your Mazda technician for required repairs or replacement.  

5. Radiator Problems

A coolant leak is usually caused by a broken radiator, which may become damaged or punctured during a collision. This issue can contaminate the oil, causing the engine to overheat and leak fluid, resulting in a complete shutdown unless quickly repaired. Fortunately, your local dealer expert can provide helpful tips on preventing damage to your radiator and how to remedy the situation if it happens.
