08 Cobolt running hot
6 months ago I suspected my cobalt had a
small head gasket leak due to low coolant
and some/little white smoke. I added some
expensive stop leak by manufacturers
directions and my issues went away. I've
constantly monitored my temp and it ran
from 190-205 till now. It gets up to 220-225
or hotter unless you turn the heat off and the
temperature drops below 210. I have no
coolant loss and changed the thermostat
and still have same issue. Temp actually got
up to 240 until I turned heat off. Fan appears
to be working fine. Any ideas?
