I'm changing the thermostats (both the EGR and the engine one). Just one major issue: I can't unscrew those two bolts which are pointed with orange arrows.
I need your advice to unscrew them, and since I've tried to use an over-the-shelf lubricant with no use I'm starting to get a lil bit nervous about it.
My biggest fear is to shred the head of the bolt, thus letting the bolt completely useless. The handicap here is that the bolts are in a hidden area , so lets say there isn't much room in there
