If your radiator is having issues, it could definitely cause your car to overheat!
If your engine is running hot and you haven’t had your radiator checked in a while, here are some of the likely culprits:
  • Leaking hoses: If one of the radiator hoses carrying coolant is leaking or otherwise damaged, your engine isn’t getting cooled like it should which will lead to overheating.
  • Broken radiator fan: The radiator fan pulls cool air into the radiator to help cool things down. If it’s not functioning, the engine temperature will spike.
  • Clogged hoses: Mineral deposits, debris, and by-products can gunk up your radiator and hoses, especially if your system hasn’t been flushed in a while.
If your engine is overheating, you need to take it to a mechanic as soon as possible so they can flush the system and replace any leaking or clogged hoses.
Making sure you stick to a regular maintenance schedule can save you from a big repair bill down the road, and having the right insurance coverage can save you even more money.
