Hello, if your coolant system is leaking, air can get into the system and create this issue. Low coolant level, poor air flow across the radiator can do this also. The best thing to do is inspect the system for the leak and check coolant flow output. I recommend a certified technician, such as one from YourMechanic, diagnose your temperature gauge.
