What started as a radiator replacement has now devolved into additional work since I have the front end apart. I got the banjo bolt off the PS pump, how do I get the steering box end of the hose off?? I've tried heat, kroil, hitting it with a hammer and steel rod to shock the nut. The flare nut wrench is rounding off the corners of the nut. Any ideas?? And while we're at it, how do you get the thermostat bypass tube out of the housing? tried heat, kroil, CLR, tapping with hammer, the thing is frozen in there.
