2019 Cx9 Started Overheating…
I’m aware of the cylinder head issues, 107k miles on it now. Seems worse when driving slower or idle. Is ok at speed.
Cooling fan is working and kicks into overdrive if we let idle as temp raises.
Coolant in the expansion tank was low so I topped that off.
So do we think it still could be the cylinder head or a water pump or thermostat issue?
