Title: Frozen Thermostat bolt
Post by: George Lollar on June 20, 2023, 18:12:52

I need to remove thermostat cover and bolt over head is frozen.  Tried penetrants and shock, heat is next, but that has complications.  To heat I need to remove injection lines and heat may impact head gasket.  Does anyone have any suggestions or magic?
