Car over heating
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.
