probably warming up...if the temperature goes above the average level, then your radiator might be low on water and coolant or the cooling fan is not working..
Because while running the cells start to respire rapidly which increases the metabolic activities and hence the temperature of the body rises.
Answer The pressure increases when the temperature rises.
Speedometer, fuel gauge, and temperature gauge.
A battery gauge "moves up and down" while running because of fluctuations in the voltage output of the circuit which it is connected to. This may be because of equipment on the circuit.
Usually the gauge in on the dashboard with all the other gauges. That way you can read it while driving.
If it is your voltmeter that drops while the vehicle is running. Most likely the alternator isn't putting out enough volts.
Can be loose connections or the alternator is failing.
It depends on the setpoint of the thermostat.
mechanical engine trouble. its about to blow up.
THere are 2. one for the gauge, and one that reads for the fan. the gauge one is located by the firewall, while the other is near the coolant thermostat housing.
my temperature gauge on my car bmw 318i give me error reading its reach red zone while the engine is cool and i already change the temperature sensor why?
I just changed the thermostat (the old one was stuck open) on my 96' Explorer. The temperature gauge will fluctuate now, getting pretty hot then dropping kinda cold. It will stabilize after you drive for a while. There is so much coolant that I think this is a way to get it all warmed up? I'm not sure, I used to have a Honda. I do know that the Exploder is running better, getting better mileage- so everything seems to be fine.
