What would cause the temperature gauge to fluctuate?
One common cause is a defective thermostat, a component that is inexpensive and easy to replace. Other causes of a fluctuating temperature gauge are a failing radiator fan, insufficient coolant level and a leaking cylinder head gasket. A failing radiator fan will be erratic.

Why is my car reading hot but not overheating?
As a general rule, you can say your car is running hot but not overheating because of a problem with the cooling system. Cooling system problems include a failing water pump, low coolant level, old coolant that is no longer effective, a faulty engine coolant thermostat or a faulty auxiliary fan.
How hot is too hot for an engine?
Normal operating temperature of new and used vehicles Of course, factors such as air conditioning, towing and idling at a stop will impact this, but you should be fine if your car is running at anywhere between 190-220 degrees.

What should the temp be on my GMC Truck?

What should the coolant temp be on my Chevy?
I though the thermostat might be broken, so I replaced it with a 180 (was a 195). Problem continues except now it goes from 180 swings up to 210, then back below 180, then to 180 and repeates this all the time regardless of how long I drive. Anyone have any other ideas?
Why does my coolant go from 180 to 210?
Problem continues except now it goes from 180 swings up to 210, then back below 180, then to 180 and repeates this all the time regardless of how long I drive. Anyone have any other ideas? New engine, new radiator, new theromstat, new temp sender…what could it be? Have you bled the air out of the system? That sounds like it might be the problem.
Why does my Chevy coolant keep going up and down?
Unfortunately just driving won’t eliminate the problem. when the cap is on it creates pressure and if there are air bubbles in the system, it will prevent it getting rid of the bubbles. The sender being in a different location is probably why you are seeing this fluctuation.
