    I am doing some interior repairs and need to remove the rear lap belts on my '90 Jimmy. The bolts have a torx head, and will not budge. The front belts were installed with a regular bolt and easy to remove. Anybody have any good advice?

    Just ran into that on an '88. They must have used an impact wrench set on "stun" to install those bolts at the factory! Had to just keep torqueing on them until they came loose. [​IMG]

    Here's a great tool to use for things that just don't want to come apart: <A target="_blank" HREF=http://www.sears.com/sr/framework/home.jsp?BV_SessionID=@@@@0893724934.0986252530@@@@&BV_EngineID=kalkhlfllmdbgfbmgclchm.0&targetPage=/product/summary/productsummary.jsp&vertical=TOOL&pid=00947641000>Impact Driver</A>

    You smack it with a hammer and it forces the bit down as it applies a quick, sharp, twisting impact to loosen the stuck bolt. Sears stores usually have them in stock.

    Heat them up with a torch.

    Almost 100% sure that they used loc tite on those things, and that rust doesn't help the exposed studs. I wouldn't use heat only because you will ruin the belts. I broke off a T-47 (that IS the correct size BTW, nott-45, not t-50) in an '86 in the yard trying to get the belts I needed. Impact is probably the only way to go.

    Try heating up the bolt a bit with a torch (not red hot though) and squirting some PB Blaster or WD40 on it while its warm. The heat will suck the lube into the threads kinda like when you solder. Then drive'ah!!

    Why do people keep calling it a Bronco!!!!!

    I broke 2 torx's then got the 3rd torx and vice grips on it too, broke that torx too. Tried every thing pb plaster heating it up, still wouldn't budge, so i got pissed and got stupid and just burned the biatche's out with the torch!!!!! I wouldn't recommend this. I'm just going to use some grade 8 bolts for them now

    Try PB Nut Blaster. You'd be amazed at the stuff it loosens! It's a lot better than WD-40.

    Here is trick that I have used with good results. I once faced the same problem you have and was at the end of my rope trying to get them buggers out. I momentarily thought about heating them up with the torch, then decided that the fire dept was too far away to take chances. I then decided to use my welder to heat just the bolts. I connected the rod holder under the blazer on the seat belt bolt, and the ground clamp on the bolt head on the inside. I set the welder to 90 amps and flipped the switch and let it cook for about a minute until I smelled it heating up. I then sprayed the bolt head with a little water to cool it down. It still took a little effort, but it then came out using the torx bit. It still dosn't make sense to me why this worked, because I would assume that the bolt would expand from the heat making it even more difficult to remove. On a word of caution I would disconnect the negative battery terminal, and unplug the harness from the computor to lessen the possibility of frying electrical items.

    the reson that work is you hit it with cold water witch if it cooled srank the bolt making looseing up just thgouth i drop that in if you keep breacking tools take a weld a nut on to the top of the bolt then you can use a normal sae or metric socket or wrench on it
