How to heat up a bolt without damaging stuff around it
(lemmy.world)
I am working on my integra's front suspension, but 3 bolts are rust welded. My impact gun managed to get one off, but the others wont budge. I hit them so much that the impact bit got too hot to the touch. Sprayed with penetrating fluid, hit it with a hammer etc.
My only other option is heat, but the problem is, that it's a wheel well and it traps heat, not to mention there is a brake hose which is very close to the area I will be heating.
How can I contain my propane torch heat to this specific bolt without damaging other areas?
That's a terrible idea and a good way to fry an ecu.
