I am seeing a part on ZZP that looks like this:
Found here: http://zzperformance.com/3800/eaton-bypass-valve.html
And a part elsewhere that looks like this:
I was researching and came across a GM part number of 1997244, but some other places say that it is for a 96-99 Grand Prix, and makes no mention of anything newer like an '06... I will look under the hood tonight to see what mine looks like, but which of these is the right one to check (plus some line and general checking for leaks) to be sure that I order the right thing? Thanks again!
