That depends on what the car is supposed to run at.
In any vehicle, when the radiator system is working correctly, the temperature gauge needle should be just below the half way mark when up to operating speed and temperature.
The gauge on the far right side of the gauge cluster is your engine temperature gauge. The normal operating temperature is at the half-way mark. If the needle raises above the 3/4 mark then the car is overheating. A light will come on also if it begins to overheat.
Needle in gauge should be midway between the 80 mark and the mark just above it.
Using a gauge and the proper type of freon, connect to the low side ac gauge. With the ac on high and the engine running fill the system to the full mark on the gauge.
Typically 80 - 85 degrees c. (Just slightly above the 80 mark on your temperature gauge)
No, the halfway mark is 1.75. (1.7 + 1.8) / 2 = 1.75
Most of the basic fiat models mark 1 and 2 don not have temperature gauges. They have a light on the dashboard that comes on if the temperature gets too high in the engine,hope this answers your question. All the higher spec puntos have a separate temperature gauge beside the petrol gage.
lsc- yes, bill blass and digital dashboard, not sure
That's a good thing. The temperature guage is supposed to show a good medium once the car is warmed up enough. If the temperature guage begins to go towards the red mark, then there is an occurring of overheating in the engine. If the temperature guage shows its under the halfway point then theres a very cold temperature climate and a possible freeze warning.
If you mean the temp. Gauge in a CAR; it let's you know the temperature of the water in the engine Radiator. If the temp. Gauge is at, or close to, or past the RED mark on the gauge, then the water is TOO HOT which means that it is boiling and turning to steam and most likely to burst one of the rubber hoses that carry the water through the engine casing. It is very very unwise to keep the engine going if the gauge goes to the red mark on it. You will cause expensive damage to the engine if it is not kept cool by the water being circulated by the fan in the front of the engine. Just stop the engine and call a mechanic instantly.
The halfway point is Kingsville, Virginia.
I had this happen on my 2003 Sequoia while under warranty. I was a defective gauge and required replacement. Type your answer here...
