Help! Can't get bolts off of Catylitic Converter. The 1st time I put my 14mm deep socket on and started turning it just spun. It seems the nut rusted so much is smaller? Oh and my dumbass already removed the other 6 bolts.

 

I had to make my way over to the Meineke shop...

They put it on a lift, TORCHED the bolts off, took off the stock Ypipe, Bolted up the new Ypipe, they gave me NEW gaskets and bolts...

$40.00 total! came back a week later to retighten the bolts...

NO CHARGE at all!

 

yea, some things u just can't do yourself...atleast without the proper equipment...everyone i know recommends going to shop to have y-pipe put on unless u have like a 99 max and up....too much rust down there and like impossible to take off bolts unless u have torch...good luck though.....

 

i think i read that spraying it with liquid wrench everyone hour for a whole day might loosen it up....

 

Well I've been doing the liquid wrench all day today and still nothing. Looks like off to the shop I go tomorrow

 

Wow I am surprized they are that stuck on a 99. If you haven't gone to the shop yet and have a torch or can get one I would try heating the nuts up until they are red hot, keep the torch on them for like 5 minutes. Use the smallest socket that will fit, when I did mine the cat bolts were smaller than the rest I hammered a socket on and used a breaker bar to get them started. The hardest part was getting the nut out of the socket after I got it off.

 

If you have a torch heat them up. And I would recommend using new hardware, its a cheap and easy future convenience.

 

Good lord, you really do not need to get the cat bolts torched off. First do the PB BLaster soaking method. If you've already rounded the nut off, use the next size down (13 mm or 1/2 inch) and hammer (yes hammer) it onto the bolt. As for the torch/road flare method, heat the flange of the cat, not the studs and you can probaly get the stud to come out. If you have access to an air impact that is the way to go. If you dont have air impact, drive car to friends house who does. Although not as strong, I replaced my studs with bolts. One of my studs was stuck, but I road flared the flange and then vice gripped it off. The size is M10(or M12, dont remember)x 1.25. And MAKE SURE YOU ANTISEIZE ANY THREADED BOLT/STUD.
