Ok so here is the problem, sometimes my Mustang will run hot (about 3/4 up on the Temperature Gauge) and sometimes it will run normal (about 1/4 up on the Temperature Gauge) but it seems to be completely random as to when it occurs. I've already replaced all the coolant hoses, fluids, thermostat, and installed a new fan clutch but it still has the same problem. Any suggestions as to why this is happening? What should I do next?

Sounds like your gauge is either just going weird, or you have air bubbles in the cooling system that need to be bled out.

Thanks for the help man, I guess I'll check out the wiring to the gauge and see what's going on with that.
