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?
Access isn't that bad, just worried about melting the brake hoses. Hitting it with a sledge? I don't have space for a sledgehammer down there lol, but a hammer didn't help much. I will try cleaning them up a bit, use different penetrant, hit it again with impact and heat
But I am looking for options on how to protect from heat
Good luck! I usually let my vehicle sit taken apart wayyy too long when I get to that point. I'm interested in what else is posted, I usually just don't use that much heat because I'm afraid to melt stuff.
