While driving the temperature gauge will go up almost to overheating then drop quickly back to normal. This happens intermittently regardless of how fast you are driving or if you are on hillls or flatland, The gauge never stays in the high range for more than a minute or two at a time.

Check for air pockets in the cooling system and bleed if present. If you have a radiator cap, take it off and look inside. If it is not full, fill it with coolant and start the engine. Turn the heater on and let the engine run until it is warm and the thermostat has opened. Continue to fill the radiator or reservoir until the level stops falling. Check for the presence of any bleed ports in the system. Bleed ports may be on the housings that radiator or heater hoses attach to or may be installed in the hoses themselves.

What happens if pressurized coolant system recovery cap is missing while driving at operating temperature?

the pressurized radiator cap is there for the purpose of increasing the pressure on the coolant and thereby increasing the temperature at which the water will boil. By driving without the correct cap or with no cap then the water will boil at 100 degrees C which will be much sooner than normal so you will run the risk of overheating the engine under normal driving conditions. Because the hot water is allowed to turn to steam and evaporate quickly you will also run short of coolant more quickly. Just drop into a auto spares shop and pick up a cap for the car as the price for it will be pocket money compared to what it will cost if you don't.

do you have access to a good scanner (that reads engine parameters like engine temp?)-your gauge could be bad, you might have an intermittent problem with the cooling fan (connector?), your thermostat could be hanging open or closed, or you might have air in the cooling system.

My car is overheating while idling, once im driving the temperature drops back to normal, i realized that the fans are not running at all, what connections should i check? could this be the cooling fan...

turn your a/c on which should send signal to cooling fans to operate, regardless of engine temperature. check for voltage on cooling fan wires. if voltage is not present check relays and fuses located passenger side front of vehicle under hood. if voltage is present, then i would replace the cooling fans

It may actually be a coolant temp sensor problem - they do have issues sometimes. I'd replace that before anything else - they're generally inexpensive (in the $20 or less range). If, when you ask for a new one, they ask you which one you want, you need the one for the dash gauge. Some cars have one for the gauge and one for the car's ECU. Your problem is with the one that drives the gauge, so get that one.
