Spotting Car Radiator Issues

May 8th, 2019 by

As rough and tough as your N Charlotte Toyota vehicle engine seems, it’s a perfect work of art that requires each moving part to work perfectly and at just the right time to make sure that every time you turn the key you’re able to drive. With fluids flowing and parts moving, one thing you probably haven’t considered that makes your vehicle tick is temperature. Overheating is a real issue with some vehicles and that occurs because the engine is unable to regulate its own temperature. If things get too hot under the hood it could lead to permanent damage and expensive repair jobs. Your car radiator is one component that’s essential to regulating your engine’s temperature and being able to spot issues will save things from getting too hot. That’s where Toyota of North Charlotte comes in!

What Does a Car Radiator Do?

Your vehicle uses an active cooling system that helps the engine to operate at an ideal temperature that allows for a smooth run. The cooling system in your N Charlotte Toyota vehicle consists of pumps, thermostats, and gaskets that all work cooperatively to regulate engine temperature. If overheating should ever occur, it means a part of the cooling system has failed and it can lead to heavy damage to essential parts like hoses and pumps.

The car radiator routes coolant to a from itself and cools the engine by using a fan. Coolant is cycled back and forth between the radiator and the engine while the fan operates and the process is repeated constantly while the engine runs. The coolant is kept at a temperature point between 190 and 210 F which is the ideal temperature for the engine to function. A faulty car radiator in your N Charlotte Toyota car can lead to a plethora of problems if left unchecked.

Here are a few issues to keep an eye out for:


While you typically find rust on the body of your vehicle, your radiator is especially prone to being found in the radiator. With temperature fluctuating rapidly, moisture builds up and rust soon follows. To spot rust, check the radiator assembly and the color of your coolant. If your car radiator coolant is dark in color, that could mean the part is rusting from the inside.


If the car radiator is left unchecked over time leaks can occur and you could be losing coolant. This can be caused by aging hoses or clamps that fail due to wear. If you spot green fluid underneath your vehicle, there’s a likely a fluid leak happening.

Mineral Buildup

As your car radiator operates normally, you can run into mineral deposit buildup. As minerals build up hoses become blocked and coolant can’t flow to and from the engine. Make sure to pay close attention to your engine’s temperature gauge.
