Im assuming that your getting your hot reading form the temperature gauge in dash.
Possibly your coolant temperature sensor is starting to go bad, or even possible your thermostat is starting to stick shut til real hot xP
There are several sensors, but the one id start with maybe is the smallest one located on the front of the engine, just right of the exhaust manifold,(the downwords pipe comming out of engine,typically 4 into 1 pipe)
Just takes a wrench, possibly a 6 or 8 mm size
Has a wire and plastic clamp attachment that you have to squeeze to release it. Some are double sided clamps, but most are single side.
Simply remove it and replace.
Both are easy to replace and not to expensive.
