Guest rick458 Posted September 26, 2003 Share Posted September 26, 2003 Well I've screwed the pooch now, All I wanted was a spring for my lower radiator hose it keeps trying to collapse, BAP-GEON, Autozone, and ORieley, no luck. Ace and True Value hardware stores no luck. the nice men tell me it is always the thermostat that causes hose collapse, so I get a new thermostat and gasket.take the Right side bolt out easily enough, and the Left one while being stubborn seems to be coming out when SNAP, it broke off level with the housing, Much whailing and gnashing of teeth follow. So I pull off the valve cover, and heat cycle the remaining portion of the bolt, x2 with a soldering Iron and PB blast, and using a 6" pipe wrench grabbed the 3/8" left and tried to back it out, once again it seemed like it was backing out and SNAP, level with the head(I didn't throw anything this time). Now I need to find a really long bit and drill it out then in with the helicoil, I will do both of them as the "good" bolt look seriously corroded, naturally the thermostat was in perfect condition and worked fine.

denny411 Posted September 26, 2003 Share Posted September 26, 2003 You need to use a reverse drill bit to drill it out. many times the gripping in the reverse direction will turn the screw or bolt out without the need for an easy out.

Guest Zachb55 Posted September 27, 2003 Share Posted September 27, 2003 mine did the same thing for the housing cover bolt. snapped off level with the rest of the housing, just drilled it and tapped it and bought a new bolt, i was even able to use the exact same diameter bolt as before cause i got lucky when drilling... good luck though, just go really slow and be sure your drill is perfectly perpendicular to what your drilling so you go only where the old bolt was Quote Link to comment Share on other sites More sharing options...
denny411 Posted September 27, 2003 Share Posted September 27, 2003 You will have to call around to your local hardware stores and maybe some welding shops. I need to get some myself. The last/only time I used one, i had to borrow one from my neighbor. I asked where to get them but he bought them at a tool auction. I`ll look online to see what I can find.

denny411 Posted September 27, 2003 Share Posted September 27, 2003 I found plenty of threads on "reverse drill bits", but only this one... http://www.ytmag.com/farmall/messages/317196.html said where to get them. Apparently... "you can get them at Napa for about 20 bucks" Quote Link to comment Share on other sites More sharing options...
Guest rick458 Posted September 27, 2003 Share Posted September 27, 2003 I will have to give it a shot, it really pissed me off because she was running very well flattops and all, just a little warm, but not hot, the lower hose was kinda football shaped thats why I wanted the spring. BTW that was the first bolt I broke on her, electrolisis was bad on the bolt that came off, hardly any threads on it, live and learn Quote Link to comment Share on other sites More sharing options...
Guest Nic-Rebel450CA Posted September 27, 2003 Share Posted September 27, 2003 Dont forget to put in some good penetrating oil. That would have been a good idea the first time it broke. Heating around the area normally isnt a good idea as the expansion also goes inwards into the threads and makes the bolt stuck in even tighter.

Guest rick458 Posted September 27, 2003 Share Posted September 27, 2003 I have been hosing it with PB Blast Quote Link to comment Share on other sites More sharing options...
Guest Zachb55 Posted September 28, 2003 Share Posted September 28, 2003 something i found very effective on removing an extremely tight oil pump bolt was to heat it up for a while with a torch, then spray penetrating oil onto the head/broken neck of the bolt, then heating and spraying again. i repeated this about 4 times and it really helps to work the penetrant into the shaft. i found the penetrant all the way through the shaft after removal. -zach Quote Link to comment Share on other sites More sharing options...
Guest rick458 Posted September 29, 2003 Share Posted September 29, 2003 All I had was a big soldering iron but I would heat it up for 10 min then hose it with the PB Blast I will drill it and use Helicoils it is a fairly low torque application so I should be OK there wish me luck Quote Link to comment Share on other sites More sharing options...
