Most common things to check for are a bad guage or stuck open thermostat
The Sacroiliac Joint barely moves during any kind of activity.
If you have manual transmission, most likely the clutch has to be replaced (as you said).
The gauge does not cause the heat; it only shows what it is.
If the fuel gauge is stuck, the needle never moves, then the gauge has a problem and needs to be replaced.
It's not supposed too.
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.
The knee is not a fixed joint it is a pivotal hinge joint; they are completely different a fixed joint barely moves where as a pivotal hinge joint moves in four directions.
Weak battery, or weak alternator.
The sun barely moves. It never will travel around the galaxy.
Can be loose connections or the alternator is failing.
Turn on your vehicle's heater
1. Instrument Voltage Regulator (small three pronged, behind the temp gauge) 2. Thermostat 3. Fuel tank sensor I have actuall had this happen in two of the four Vanagons I have owned. The Instrument Voltage Regulator solved it for $20
