I'm not sure if he'* a newbie or not, but the last two times I've been there it'* been him.
If I had a part number I could back back and say "this is what I need". Then I could kind of rub it in and say 'see, the part is on my car and GM makes it'.

Thank you very much!

Just a few more questions and I'm off to find the part..
Since I haven't started disassembly yet, how does the bypass elbow fasten to the intake
Is it just pressed in?
Is there any special tool required?
Any thing I should watch out for when replacing the elbow?

Your old LeSabre was a Series 1. The Series 2 doesn't have a metal option yet.

Default DONE!!!

Found all the bolts without too much problem and it is running again. Whew, I'm hoping this lasts for awhile now. Only one snag, as I was warned . . . I broke the elbow (not the plastic one the aluminum on the tensioner). So off to Advance Auto Parts for a new
$74.00 part. Still a heck of a lot cheaper than taking to a mechanic for all the above mentioned repairs. Just for reference if you buy the tensioner assembly you also get the plastic elbow that everyone talks about. Since I already had one from the dealer, I used the dealer elbow and will keep the other as a spare.

I only ran it for a minute to make sure it was stable and not leaking. Now I have to find the post on flushing the air out of the coolant passages and I'll take her for a longer test drive.

Thanks again for the advice, this is a great board with a lot of activity!

Lance
