Low Coolant? Weak Temerature sensor? Weak gauge Gauge working properly and recording the thermostat opening and closing as engine temperature fluctuates
When you turn a corner the guage fluctuates.
Your pressure gauge may be broken....If it fluctuates, then you know its not your gauge, but if your gauge always reads 80, it may need to be replaced.
because your thermostat is opening and closing as the engine temp. fluctuates
The temperature gauge on a car fluctuates because the car's thermostat is opening and closing. The gauge goes up when the thermostat closes and the gauge goes down when the thermostat opens.
The gauge does not cause the heat; it only shows what it is.
The oil pressure gauge on a 2002 Ford Taurus is located right next to where the battery is, toward the middle of the actual car. The gauge is connected to the front of the engine.
Could be low on coolant or a faulty thermostat.
I just bought a fuel pressure gauge and it comes with a book. In that book every make and model imaginable. I have a Ford Taurus and the pressure for yours should be 40 psi
Because it is a Pontiac. Sorry, man.
check the antifreeze
The gauge is part of the fuel pump/float assembly within the gas tank. It is probably a $500.00 repair. It is harmless.
