Head gasket stop leak products can temporarily seal minor leaks in a head gasket, but their effectiveness depends on the severity of the damage and proper application. It’s a stopgap solution, not a permanent fix. Severe issues will require a proper head gasket repair.
Your 2008 Chevy Uplander may overheat when switching to heat due to low coolant levels, a clogged heater core, or a malfunctioning thermostat. Check the coolant level first and inspect for leaks. If the coolant is fine, the heater core might be blocked or air-locked, or the thermostat could be stuck.
