How can I test my temp sender or sensor?

[SHOblime]

Hey my temp gauge is permanently at C, I doubt this thing runs THAT cool, so how can I test my sensor? I have a DVOM, what are the specs? Is there a FSM online somewhere I can check out? I can print out instructions at skool (we have shopkey and alldata) but I'd like to test it tonight if possible. the list of replacement parts is getting longer and longer (radiator, hoses, temp sensor, etc)

Unplug the wire at the sending unit, ground it and see if the guage reads full scale.

If it does, just replace the sender unit.

If it doesn't, the sender is not the problem.
