I am installing an oil pan on my SUV listed above (XL model) and I was just wondering the bolt sequence and also I have a brand new set of bolts from I c Billet but they say they are for an LS will those bolts fit on my oil pan?

These bolts should work with no issue. However, when you remove the existing bolts just compare them side to side and that will confirm they are the same length and pitch. However, I am sure they are and you will have no issue.

I am attaching the info below from the manual on how to replace the pan. Please run through this info and let us know if you have other questions on this.

Thanks

Well, they are definitely not the same size so I guess I'm going to try to just use the old bolts maybe put a little Loctite on them so they don't loosen.

Oh wow. That is surprising that they are that different.

However, oil pan bolts are fine to reuse because you are not tightening them that much. The ones that you need to be careful of are head bolts that are actually stretching the bolt. They are called torque to yield bolts. These are not so I always reuse the oil pan bolts.

If you are going to use Loctite then just be sure to use the one that says it is removable. Clearly these need to come out so you don't want them getting stuck and then stripping or braking if you have to remove them again.

Thanks for the update with that info. That will help others that visit the site with the same question. Thanks
