Water Temperature Gauge

[uoapsdb]

As opposed to the oil temperature guage.

During a run, the water temp guage can operate normally for a while, then will display 0, then displays the temp again.

My immediate thought was that the water was a bit low.

Please can someone explain how to check the water level, I can't see a mark in the reservoir.

Should it be at the bottom of that plastic cylinder in the resrvoir, top, middle or what ?

Thanks Steve

theres a black marker if you look close you will see it,
its on the inside, its not Marked on the header tank its self

Temp going up and down couid be one of a few things,

: Airlock,
:Faulty Thermostat,.
: No thermostat, (someone Removed it )
: Faulty temp sensor,
