I have a Fiat Panda and i really need help. last week my engine over heated (photo 2). Normally and since i bought the temperature gauge has always been midway (see pic 1) i went to a few people including two back street mechanics and one Fiat dealer. They all filled up the water bottle and said that would do it. however all of a sudden my car now starts on the “C” ( see pic 3) as this has never happened before this feels wrong to me, but am i right ? My mate at work had a look at this and said that the 3 others had filled the water too hight and when i looked he was right and it was to the top and the max line was well below. so i filled with the universal coolant and it seemed to do a little better. Today after I drove 2 miles and the dial move slowly from the “c” to about 25% with in 2 miles. what is concerning me is now when i now drive and i DO NOT have the heater on hot air vents through any vent in the car. It’s unbearable. with two young kids in the car its not good.
I feel now that the thermostat is the problem. but im not a mechanic and im only going on what some people has said i may or may not be be.
Can you guys help me???
