Well it's funny, because I just got a new radiator and thermostat in late December. And my car's been doing fine. Now all of a sudden, the temp. gauge goes up almost to hot! I put my heater on, and it went down and I got it home. What could it be? Mechanic's Assistant: Has the vehicle overheated in the past? And what about servicing? Is it up-to-date on oil changes? It hasn't overheated in the past, as far as I know. I've only had it for less than 2 years, and it's a 2014, so it' not old! It did have the radiator replaced, because it was leaking coolant. Also, I had an oil change at the same time as I got the radiator and thermosat fixed. Mechanic's Assistant: What is the make/model of your '14 car? It's a Hyundai Accent. Mechanic's Assistant: Are you fixing your Accent yourself? What have you tried so far? I don't know how to fix it, really. I took it to my mechanic. I did put the heater on, and the temp gauge went down to normal and stayed there until I got home! Mechanic's Assistant: Anything else you want the Mechanic to know before I connect you? Not anything that I haven't told you.

Howdy from Tennessee, I'm Chris aka Moose. Who am I helping today? I'm glad you've come here to get help. I will do my best to get the answer you are looking for. I help many customers, so sometimes my replies are delayed, I will respond once available. I try to be online at 1-5 pm and 10 pm-5 am every day. The remaining possible causes can be some sludge buildup in the cooling system which is blocking the flow through the thermostat and radiator partially. The water pump impellers are corroded and not moving enough coolant. The head gasket is leaking allowing air to be packed into the cooling system. The cooling fan not working. These are the things that need to be checked through testing. Thank you for seeking us for help, I hope I provided what was needed. Press reply if you need to follow up. If you liked my answer please let me know so I can mark your question complete. Moose

I liked your response, I'm hoping it isn't anything really expensive to fix. I'm going to be taking it to my local mechanic tomorrow. But I just wondered what it could possibly be. Like I said, it was fine after being fixed late, this past December. I was puzzled to what it could be now? Can a thermostat go out that soon, or a radiator?

A thermostat nor radiator failure over a couple of months is unlikely.
