Rear Hitch Install - stuck bolts

[teppichkopf]

01 Forester. I have a few stubborn bolts on the tow hook. Anyone try some heat here? I'm not sure that it's a good idea, assume the bottom rust inhibitor and whatever insulation is above that might burn.

 

So far 2 of 3 on passenger side aren't budging. Have used 24-inch breaker bar, air-impact wrench, and PB Blaster (sprayed a few times and let to sit for 2 hours.)

 

Definitely don't want to break off the head and go down that road.

 

Anyone find a better product than PB Blaster?

 

Luckily I'm not in a hurry to get it installed but want it off the "summer to do" list.

when i installed mine, i didn't have to remove any bolts and my tow hook is welded on, i think.

 

of course your ford pick up may be different than my 97 outback.
