laguna temp gauge not working

Renault Laguna 2.0 RT Petrol, 1994.
After a mechanic dug around trying to solve a starter motor problem, my temperature gauge has stopped working.
When turning the ignition, the gauge lights up and the needle moves (does this reading give oil temperature? I've never had a manual) but once it settles down to read the coolant temp, it reads zero.
Is cooling system fine without the temperature gauge working? A bit worried about blowing up engine!
Also, is this likely to be sensor problem or dashboard?
Thanks to all. Getting a little fed up with my poor old Laguna.

There are 2 sensors that are used for temperature sensing. 1 that screws in to the front of the engine for the ECU and one that screws in to the back of the engine, somewhere near the thermostat housing that supplies the dash with its temp reading. Perhaps check that the plug is connected to it properly?
