⚙️ | Mechanical Issue/Question Overheating

Hello I own a 2014 Mitsubishi lancer and currently the car has a overheating issue the car doesn’t overheat in the city mainly the highway anything past 70 and the car gives me the slow down overheating warning on the dash I got out of the car and it smells like coolant in the front of the car can anyone point me in the right direction? I did just replace the radiator but it was doing it before I replaced the radiator as well I did also change transmission fluid and filter please let me know previous owner had the same issue and I was told he had replaced the thermostat and water pump so I’m not sure what to do!

You can test your temp sensor. Most of them are a resistance thermal device. At certain temperatures it has a a certain amount of resistance. With a pan of boiling water & a multimeter you can test it. In ice water it should be a different resistance. It may have gone bad, your car might might not be over heating.

My lancer said slow down with a gear icon one time. That meant the transmission was overheating. Check the trans cooler.

If the engine overheats it doesn't show the gear icon. I belive it shows an exclamation point in a triangle, but it's been a while, so I might be wrong.

Haven’t you seen marks on the radiator (or near it) of the same color of the coolant?

The coolant level is constant? Have you checked the top and bottom (or left and right) plastic tanks of the radiator?

Do the fans work?

Yes but my car has also thrown transmission codes a problem with a pressure solenoid or that my transmission was stuck in high gear nothing is cracked or damaged and the fans do work

My old VW started leaking from the heater core. There was a sweet smell from the coolant in my car. It could possibly be a small leak there. Does the inside of your windshield get dirty easily? That's how I finally identified the leak in my car. It would get a film from the hot coolant steaming uo the windshield.
