Question type: Maintenance & Repair

I have a 06 Infiniti g35x , I just replaced the  
thermostat  last month, but now the temp
gauge goes up to H and then back to mid
level. What can be causing this?

Thermostat, it's sticking.

Radiator might be gunked up and system needs a flush. I would pressure test the system to check for leaks as well. Good luck!

Possibly low on coolant. Purge the air out. Look for how to videos on Youtube.
