I just swapped in a new oil pan in place of a cracked pan in my '99 WS6. I figured out while trying to install a new oil filter that the threads are different (bigger)! After a quick search here, I learned that GM decided to switch threads in the newer pans.

That said, what filter do I need now? I found some filter #'s upon searching, but I always use Napa Gold filters & didn't find a new part # for that.

Also, it would actually be nice to know what I need to ask for a filter for if I ever decide to go to a different brand filter. A filter for a '99 Trans Am obviously isn't correct any more.

Anybody know what I need to ask for?

Thanks!

im believing you can ask for a 2007 gmc classic with the 5.3 an it should be the right size for you, Cause i know a delco pf46 filter wont work on them cause the threads are bigger,

I found this searching not sure how accurate it is. "The same engine (LS2) used on 3 different model years requires two different filters. The LS2 used in 2005 and 2006 models requires a PF46 and the LS2 in a 2007 requires a PF48, which is also used on the 2008 LS3"

Does it have a oil filter on it now? I would just cross reference that number to the brand that you want to use

Should be 10060.

Just took a chance on a PF48 & that was the one.

Thanks for the help!
