Why Is My Car Overheating?

2022 Jaguar E-PACE Interior Profile
Seeing steam from the hood or watching your temperature gauge spike can be a stressful experience for any driver. If you are wondering, “why is my car overheating?” it is typically a sign that your cooling system is no longer able to effectively dissipate the heat generated by the combustion process.

Understanding what causes a car to overheat is the first step in preventing permanent engine damage and avoiding expensive repair bills. At Jaguar Rockford, we want to ensure you stay safe on the road, which is why we’ve put together this comprehensive guide on identifying cooling issues and knowing exactly what to do when a car overheats.

There are multiple reasons a car would overheat, from a leak in the cooling system to an issue with the radiator. Everyone’s vehicle has a “normal” place for the temperature gauge to sit, but most cars generally operate between 195 and 200 degrees Fahrenheit. If you start your car and notice the temperature gauge is reading far higher than normal, do not drive the car. Driving an overheating car can put you in danger, and it will only cause bigger, costlier issues down the road.

Take an in-depth look at what causes a car to overheat with Jaguar Rockford below, and contact us if you have any questions.

What Does It Mean When Your Car Overheats?

Overheating is a clear signal that there is a bigger issue to address. See below to learn common causes so you can prevent this from happening:

  • There’s a leak in the cooling system: Most often, a leak is what’s causing your car to overheat. Components: The radiator, hoses, water pump, head gasket, and thermostat housing are all susceptible to leaks.
  • There’s a problem with your coolant: If the wrong coolant was used, or you have an improper coolant-to-water ratio (50/50 is proper), your engine may be prone to overheating. Consider a coolant flush if your fluid looks contaminated.
  • There’s a blockage in the coolant hose: Dirt and debris from the road can enter your system, leading to significant blockages that prevent fluid flow.
  • There’s an issue with the radiator: A blockage, leak, or damaged cooling fan can prevent the radiator from lowering fluid temperatures.
  • Your car’s water pump is broken: The water pump is the heart of the system. If it suffers from a leak or a shifted pump shaft, coolant cannot circulate through the engine block.

What to Do When a Car Overheats

Unfortunately, your car may not overheat until you’ve already hit the road. If this happens, follow these steps to maintain safety:

  1. Adjust Climate Control: Turn off the air conditioning and run your heat at full blast. This helps pull excess heat off the engine and into the cabin.
  2. Stop Safely: Turn on your hazard lights, safely pull over to the side of the road, and stop driving immediately.
  3. Wait: Do NOT attempt to open the hood for at least 30 minutes. This prevents severe burns from escaping steam or boiling coolant.
  4. Ventilate: Once the engine has cooled down, pop the hood to allow remaining heat to escape and signal to other drivers that you are stationary.

Once you are safe, the next step is to call a towing service to bring your vehicle to a certified service center for a professional diagnosis.
