I'm going to assume your gauges are not working?

 

Temp gauge... If gas gauge works then not the fuse.

 

Find the sender, should be below the top rad hose where it leaves the thermostat . It will have a single Yellow/Black stripe wire to it. Check that the wire is connected, that it is clean and securely attached. If still no reading ground this wire to anywhere on the intake and your gauge should read full HOT.

 

If YES the sender is no good.

If NO it's likely in the dash, wiring or the gauge is not working..
