Check engine and AC fan shud be working and thermostat shud be there and working too. In American cars better have gcc specs thermostat fitted that open and close at little lower temperature like 83 degree than 90degree in US spec cars.

Its under the engine near the crank case on left side, plugged with wire and fitted little inside.

Check the release lever, there may be something stuck behind it. Dont press hand brake more it will get worsen.

Its is under the hood near to the passenger side near the front with a black top on it having a fuse icon embossed

check spark plug and coil first, if not may be fuel pump is dying (very rare though).

May be or more than likely your gauge/sensor is gone bad. Check the heating temp by hand of hose from radiator to engine when its at normal running temp (also press that hose little bit to see how hard and soft it is), then when it shows overheat check same hose again by hand and press also little bit to see if that becomes more hard and hotter than before then its actually overheating. If not then temp gauge or water temp sending sensor is gone bad. Change the sensor first its cheap, and then gauge. Hope it helps

There are two fuse boxes in eldorado. One under the hood and one under the back seat.

the traction control light is on but i am not facing any problem while driving. cud this be only a sensor issue or cud it seriously a traction issue that i cant notice . please advice
