The Aztek has been known to have screwy gas gauges. Mine "floats" from E to F and sometimes shows the actual level. I've heard it's a bad sending unit in the tank causing the problem. If your gauge just lies there, it's probably that the sending unit is done.
it's located in the fuel tank on the fuel pump
thermostat may be sticking and that cause the gauge to show hot, have it checked soon, you could be headed for bigger problems
temperature gauge not working can be caused by a bad temp sensor in engine, a bad gauge in dash, or a bad fuse
My oil pressure gauge is dropping to o and the oil was just changed and is full. What could cause this
Go to a Pontiac Mechanic and spend a few bucks.
Because it is a Pontiac. Sorry, man.
Coolant Temperature Sensor
The gauge near the filter of the pool will tell you when the filter needs cleaning, the higher the gauge reads the more backpressure is caused by dirt in the filter, most gauges have a red section that indicate the need to clean the filter.
The pressure gauge will generally read 10 PSI higher than when the filter was clean. In any case do not let the filter gauge go above 40PSI.
Check with manual gauge - if pressure normal - could be defevtive oil pressure sensor or gauge
Yes, special order.
this usually means that the multiport valve in the filter head is bad.. the gauge is not always accurate. replace gauge. the impeller in the pump can also be cloged not allowing you to get any pressure in your gauge. the backwash will be very slow if not any..
