Check your fuses. If the fan isn't running to draw the heat away, it could be the fan. Then, look for other things, when was the last time your cooling system was flushed? Those start at the cheapest & go up from there. If it keeps over heating, you could damage your engine.
Sitting still aka idoling is worse for overheating then driving. While driving, you get some airflow around the engine. While it just sits there, if the fan isn't working, there's no airflow at all, causing the engine to heat up pretty easily.
Change da violent, check for leakage in radiator. Or best consult a mechanic for a free advice or you pay him whatever you like.
The electric fan(s) isn't coming on for any one of several reasons, either the fan motor is broken, the thermostat that tells the fan to turn on in a specified heat range is malfunctioning or the relay that actually turns on the fan is malfunctioning. Or it could be a blown fuse. An idling car (fwd) does not draw air through the radiator and as the fans can no longer be driven off of the crankshaft (because the shaft is parallel to the front bumper and the radiator is too, so it must rely on an electrical circuit to operate the fan.
Does it only overheat while idling? If so, it could be an issue with the fan not coming on or a deteriorating radiator but considering it's only 4 years old, I'd suspect a fan issue first.
Have you taken the radiator cap off and run the motor for 15 minutes to see if any air bubbles come out? Checking the coolant is the first thing to do.
Next replace the thermostat if the coolant is ok.
When you turn on the AC do the radiator fans come on?
Most common reason is the radiator fan not coming on.
When you are driving there's enough wind through the radiator to cool the engine, so the fan isn't on. When you stop, no air flow, so the electric fan needs to switch on to cool the radiator.
So faulty fan? Relay? Wiring? Etc.
- Ford Ranger 4.0, 172,000 miles rough idle when starting after sitting overnight or after 2-3 hours. Starts 1st crank, idles rough 1 minute? Or so and then smooths out and runs fine. New heads and gaskets. Cleaned MAF sensor, throttle body and air intake sensor, new IAC valve, new air and fuel filters, new PCV valve. No smoke coming from exhaust and No check engine light. Any ideas what's causing this rough idle?

- I just got my car in January. Two weeks ago it ran hot. It Ford Focus 2014 . For my understanding I got extended warranty? Ok I just got my car in January. Two weeks ago it ran hot. It Ford Focus 2014 . For my understanding I got extended warranty my radiator completely went which blew my head gasket. The mechanic want me to lie And make insurance claim. Which doesn't seem right to me?
- Why does my truck overheat when I turn the heater on? I own a 1989 ford f150 standard cab 2wd 4.9L 5-spd manual. When ever I turn my heater on (winter) and it starts blowing hot air, my temperature gauge starts moving towards hot. I find this very strange because I'm pretty sure it's supposed to take heat away from the engine.
