Temperature guage not reading anything. Had a water leak which has been fixed. No air in system. Thermostat has also been replaced. Any ideas where to look?

...Iffy sensor or its electric connection is the first place to start looking.

As above.. check wire to sender is still attached, if so change the sender unit as may have gone faulty.

The casing of the gauge needs to be grounded. You need to check the continuity of the wiring from the sender to the gauge. The sender might be faulty. You might still have an air lock in the cooling system. The live feed to the gauge might be faulty.
