Your car’s radiator is as important as the engine itself; without a functioning radiator, your vehicle has no way of getting rid of the heat it generates. If your radiator is failing, it needs to be addressed since excessive temperatures can seriously damage the components in your engine bay. This can be tricky, though! The radiator system is complex and isolating the problem can be a little difficult. That’s where we come in! In this article, we’ll show you how to analyze the problem to determine if your radiator is dying or needs service.
Things You Should Know
- The radiator is responsible for cooling your vehicle, so any overheating is a sign something is wrong.
- Look under your vehicle and inside of the engine bay for leaking coolant or bubbling around the radiator cap.
- Coolant rarely needs to be refilled, so if you find your reservoir goes empty regularly, it’s a big sign there’s an issue.
- Inspect the radiator visually at the front of your vehicle to look for cracks or buildup on the fins.

You can try to fix the radiator yourself by replacing lines, sealing leaks, or swapping the radiator fins out if you’re a gearhead. However, this is normally a job left best to mechanics.Thanks
