Just bought a new thermostat for my gmc Sierra with a 350 in it and it has started making a ticking noise now after replacing thermostat and can't figure out why?

During the work did you disturb the fan shroud or anything of the sort to cause the fan to tap the shroud? Even leaning on it to work on truck will do that. Also would be coincidence but simply check your motor oil

Did ticking sound start as soon as you soon as you started the engine or after it warmed up?

New thermostat= it got hot. Right? HOW hot for how long?

After it was warmed up. It made the sound when I shut my truck off. And I haven't drove but maybe 20 miles in the last couple days since it's had the new thermostat. My temperature gauge won't read anymore either.

You probably pulled the wire off the temperature sending unit. It's right next to thermostat housing
