I am in the middle of doing an oil cooler on my Excursion. As usual this truck is fighting me tooth and nail!

I am to the point where I am ready to pull the turbo. The only thing left to do is take the 3 bolts out and pull the turbo. Sprayed liquid wrench on them and the first one I tried to loosen up rounded.

Any suggestions folks? I am at the point to call the hook truck and have it towed to a repair shop.

 

Wish i knew how to help on this one. Man I hate that. Last time I rounded one off I had to spend 500 bucks for a 20 dollar job.

use 6 point sockets only, the 12 point ones will only create headaches for you.

 

Flame wrench.

 

Snap on and Matco have sockets for that. If the bolt or nut is rounded the socket has sharp edges to bit into the bolt. As a tech these sockets are worth every dime. You may need to heat the bolts up to remove then hit them with a good penetrating oil. The socket set Is about 150.00 or you can just buy the one you need. Don't use liquid wrench buy a good penetrating oil like nut buster or wurth.

 

Go to Sears and get their nut off set, its worth the trip

 

I just weld a nut on. the nut gives you a new flat surface, and the heat helps loosen it. Also 6 point sockets only.

 

I have a set of these made by Irwin. Got them at Lowes I think.

 

Have you used Koril?

The other thing that I like is the inductive heater tool

Works nice and a very handy tool to have.
Just like a flame wrench.

If you can fit the bolt out sockets on there they are great I bought the full set over ten years ago for a starter bolt on a Cherokee. They have saved me many times over the years. Same design as the Irwin ones pictured.

 

Many socket have a bevel on the inside to allow a little wiggle when your using them and make it easier to get it on the bolt head.



Sometimes all you need is that little extra grip and grinding the face of the socket flush does the trick.



As mentioned, a six point socket is much better and don't use any wobble adapter or wobble extensions on bolts that are being a problem. No only will they be the first thing to break, it makes it much harder to stay on the bolt straight. After "prepping" the socket, get it on the bolt and give it (or the extension if your using one) a solid wack with a decent size hammer. Obviously, if you have expensive tools you may want to keep a few klinker tools around for this kind of stuff.

Also as mentioned, penetrating oil and heat are also helpful on those tough ones.

And finally it's possible to heat the head of a bolt with a torch and just blip the O2 for a second and blow the head off it cleanly. If that allows you to get the part off and leave the stud sticking up, it will often come out without too much headache. Kind of a "wrecking yard" mentality but it can be done pretty sweetly if you have a torch (and skills).

 

Can always spot an aviation guy with mention of kroil

Kroil is nectar of the gods!

 

If it is then why does it smell so bad

And try some good old PB Blast or WD 40.
