Common Causes for an Overheating Vehicle

Anyone who has ever suffered an overheating vehicle knows what a hassle it is. Not only can an overheating car, truck, van or SUV leave you stranded, but the tow and repair bills can add up quickly. There are several potential reasons for an overheating engine, and in many cases, you can have several of these problems at the same time:

  • Low coolant level: This issue is easy to verify and correct. We suggest checking your coolant level before every major trip, especially in the summer, and at least once a month for normal driving. If your coolant level drops below the minimum level, your engine can quickly overheat.
  • Coolant issues: Your vehicle is designed to run on a specific type and blend of coolant. If you choose the wrong coolant or get the mix wrong — most vehicles run on 50% coolant / 50% water — it can cause big problems. You can find information in your owner’s manual for the right type of coolant to use.
  • A broken water pump: Your vehicle’s water pump is responsible for circulating coolant throughout your engine and radiator, where it can be cooled down. A leaking or faulty pump is a common reason for vehicle overheating and requires immediate attention.
  • A blocked radiator: Blockages in your radiator tubes or the exterior fins can reduce the effectiveness of your cooling system. It may be necessary to drain and clean your radiator and wash the outside to remove dirt and debris so coolant and air can flow freely.

While it is important to keep an eye on your coolant quality and level year-round, overheating problems are much worse in the spring and summer, when the warm weather hits. One of the best ways to ensure you aren’t losing coolant is to watch for signs of leaks and fix them before they become a major hassle.
