Coolant Level too low (or sensor went bad)
or
Engine Compartment Temp too high / engine compartment fan failure
It means the engine may be overheating.
engine coolant
Your engine coolant temperature gauge has a sensor ( there is also a engine coolant temperature sensor that is used for the computer / PCM )
A signal from the temperature sensor on the engine.
The average aircraft will have temperature gauges for the following: Outside air temperature, Engine air inlet temperature, Engine exhaust temperature, cabin temperature, and that's just on a small aircraft. So which temperature gauge do you mean?
Switch the ignition off and start the car again.The light will then stop flashing.
No - the gauge reports 'real-time' the engine temperature. If it is wrong, there is a problem with the sending unit on the engine. This is a pretty easy fix...
i just put in a new radiator and now temperature gauge reads high but their are no leaks
It is an electrical device that tells back the engine temperature to both the temperature gauge and (where fitted) the engine management system.
usually on the left of the engine between the first two spark plugs
There are two kinds of engine temp gauges available for VWs. One is the Oil Temperature Gauge, the other a Cylinder Head Temperature Gauge.
Low Coolant? Weak Temerature sensor? Weak gauge Gauge working properly and recording the thermostat opening and closing as engine temperature fluctuates
