What should I do when my Kia Sportage's engine starts to overheat?

My Kia Sportage's engine temperature gauge has been consistently showing signs of overheating. What are some steps I can take to troubleshoot and address the issue?

First, check your coolant levels and make sure they are topped off. If the levels are low, it could be a sign of a leak or other issue with the cooling system. It's also important to regularly check and replace your coolant, as it can break down over time. If your coolant levels are fine, the problem may lie with your radiator or water pump.

Another possible issue could be a malfunctioning thermostat. The thermostat helps regulate the engine's temperature and if it's stuck closed, it can lead to overheating. If you're comfortable working with cars, you can try replacing the thermostat yourself, but it's always best to consult a professional mechanic.

In addition to checking and replacing your coolant and thermostat, it's important to regularly check and replace your engine oil. Old or dirty oil can cause your engine to overheat. If you're not sure when your last oil change was, it's a good idea to get it done as soon as possible.
