That sounds like the classic symptoms of a cracked ECTS (temperature sensor). It is located on the head near the upper radiator hose and battery. You will see two wires (likely a yellow and a black) going to a small sensor hiding in a little cubby hole. If you pull off the connector (there are two points that if you squeeze it lets the connector come off) you will probably see that the connector is corroded because the plastic body of the original ECTS cracked and let a small amount of coolant into the connector. The ECTS is only about a $10-15 part, be sure to get the updated one with a brass body. Then the hard part is you will likely need to get a new connector, one of the best places for that is a junk yard, the temp sensor for the transmission and the air temperature sensor near the air filter use the same connector. When putting this in be sure to solder the connections and cover that with heat shrink tubing. There are video's from Richpin06A on youtube that will show you how if you have any doubts. The saturnfans forum is a great place for info too,

Possible bad water pump or a blown head gasket. if you take off the radiator cap and the coolant looks chalky, it is oil mixed with the coolant. also with the cap off and the motor running there is no circulation either the pump or thermostat are bad....

Temperature gauge keeps fluctuating whats the cause


Fiats have a reputation for electrical/electronic problems as they age and even when they are not very old they can manage strange things that even sometimes defeat the dealers, though the same can be said of many modern vehicles. I used to look after a Ducato motorhome and fortunately didn't need to get involved with much electrical work - the only faults were caused by the coachbuilders rushing around and being careless and not by Fiat.

I am not sure if the temp gauge is driven by the engine management or is a traditional circuit but either way the temperature gauge is in effect a voltmeter of sorts. Assuming the gauge is ok, the reading will only fluctuate if the voltage in the circuit fluctuates and that could mean the supply voltage is fluctuating or the resistance of the ground path is fluctuating.

With the traditional circuit the gauge is supplied by an electronically stabilised voltage and the ground path resistance is varied by the engine coolant temperature sensor and fluctuations could be anything from a faulty instrument voltage regulator, through faulty wiring or connections to the temperature actually fluctuating.

If the gauge is driven by the engine management the same approximately applies but checking the circuit becomes much more complex due to the need for circuit diagrams and specialised test equipment, though these would not be needed just to check the security of the gauge in the printed circuit of the instrument panel.

How to tell if car is actually overheating


If you have a temperature gauge it should stay at or just below the middle when the vehicle is fully warmed up. Slight (very slight) fluctuation on the gauge is normal. This is all dependant upon having proper flow of coolant through your coolant system. If, for instance, your water pump is broken, there is no flow of fluid acros the temperature sensor, thereby giving you a false reading. The temperature sensors in the car need the fluid to flow across the sensor to give a true reading. When the car is fully warmed up, squeeze the top radiator hose hard a few times. You should feel moderate resistance and then you should feel the surge of coolant back through the hose as you release it. If you dont, your water pump may have quit working or you have a sizeable blockage in your coolant system.,

1999 VW Cabrio dash light


Obviously it's temperature gauge light. Check for coolant level first. Then check for coolant leak. If coolant is leaking out of your car, the lower coolant levels in your engine will cause it to overheat. If you have your heater on and it starts blowing hot air instead of cool, your engine is low on coolant. This will cause to flash a warning light on your car's dashboard.

Guages not working,


If all voltages checked ok,then most probably its faulty instrument cluster board on which gauges are connected.Yes if cluster circuit board looks ok,then also it can be faulty.Somewhere there is minute short or burn on board then such prolem arises.
Also check the fuse box.One under hood and other under dash.Inspect each and every fuse and see if all are fine or not.

No guages working


If all voltages checked ok, then most probably its faulty instrument cluster board on which gauges are connected. Yes if cluster circuit board looks ok, then also it can be faulty. Somewhere there is minute short or burn on board then such problem arises.


Also check the fuse box. One under hood and other under dash.

Inspect each and every fuse and see if all are fine or not.

I just had the same problem happening with my 2006 PT Touring. Took it to the dealership. The issue was the electric parts of the ignition switch. They replaced it and all is well in the world again.

I'm thinking the coolnat level is low, and this might be caused by a bad head gasket - At least $800 to fix - sorry.
