Why Is My Car Overheating?

The complicated mechanics of your Porsche engine create a lot of possibilities when you have to ask yourself, “Why is my car overheating?” From a leak in the cooling system to an issue with the radiator, the culprits are many if you’re running hot on Lakeway roads. And while most cars tend to operate between 195 and 200 degrees Fahrenheit, every vehicle has its own “normal” place on the temperature gauge. One thing is for certain though: if you start your car and it is hotter than normal, do not drive. Driving an overheating car can not only cause more damage, but also put you and your passengers in danger. Instead, consult your local service center.

Below, we’ve written an in-depth guide to diagnosing engine problems. Feel free to contact the Porsche Austin service center near Lakeway with any questions. about everything from maintenance, to Macan interior features, to Panamera pricing.

What Does It Mean When Your Car Overheats?

If your car is overheating, there’s likely a bigger issue. Below, you’ll find the most common reasons that cause overheating:

  • There’s a leak in the cooling system – A leak in the cooling system is the most common problem when it comes to engines that are overheating. The radiator, hoses, water pump, head gasket, and thermostat housing are all components of the cooling system, and all can be susceptible to leaks.
  • There’s a problem with your coolant – If the wrong coolant was put in your car, or you have an improper coolant-to-water ratio (50/50 is proper), or your coolant level is low, your engine may be prone to overheating.
  • There’s a blockage in the coolant hose – The next possible culprit is the coolant hose. There are plenty of opportunities for dirt and debris to get in your cooling system on Round Rock roads. Unfortunately, this can cause blockages in the coolant hose.
  • There’s an issue with the radiator – Radiator issues are another common reason a car would overheat. There could be a blockage, a leak, or something wrong with the radiator fan, and all could cause a car to overheat.
  • Your car’s water pump is broken – The water pump sends engine coolant throughout the cooling system. Yours may be suffering from a leak or a shifted pump shaft, both of which often cause overheating.

What to Do When a Car Overheats

Unfortunately, your car may not overheat until you’ve already hit the road in Bee Cave. If you start to overheat while you’re out and about, turn your air conditioning off and turn your heat on full blast. Uncomfortable, we know, but it will help. When you find a safe place to pull over, do not pop the hood immediately—wait at least 30 minutes. Waiting to open your hood when your engine is overheating will help maintain safety for you and nearby drivers. Ideally, call a towing service to take your car to your mechanic or a certified Porsche service center.
