Add this to the list.

And yes, AC Delco still available on Rockauto for $54.79.

I will order. $66.38 shipped after tax and discount.

I better start driving this thing to work so I can shake it down before the LeMons fall rally. Sheesh. I heard sitting is good for cars, especially outside. Side note, my CTS-V has been garaged since 2010 and sat every winter. I have had approximately zero issues from doing this and it's going on 10 years now. So there.

No but I got the lines. Hopefully this weekend, though I better soak the fittings tonight so it has a chance to work in. Do not want a repeat of the Fleetwood disaster which required a new radiator.

Did the oil cooler lines today. I soaked the crap out of the fittings at the radiator.

The nuts are 16mm. I don't seem to have a flare nut wrench in that size but I guess my open end wrenches are quality. The upper nut loosened without too much of a fight.

Can't say the same for the bottom one. I just did different combinations of the 16mm wrench, vice grips, PB, and a torch. I was desperate not to crack the end tank. 11 or 12 years ago I did just that on my Fleetwood and pointlessly had to replace the radiator. Eventually it loosened but I was careful not to stress the plastic end tank too much. I could see it flexing. As the nut came loose it twisted the rusted line which was just fine. I was considering breaking it off so I could use a socket but that was not necessary. I never rounded off the nut or anything.

Ratcheting box wrench being totally awesome to get the nut off the stud that holds the lines onto the oil filter adapter. Fit in there perfectly with no room to spare.

To remove the line I had to disconnect the low oil level sensor plug and fish it out from between the lines. Same with the driver's side O2 sensor wire. That took a little fiddling but not terrible. Then I was able to pull the old lines out from the front.

Got the new lines in and upper nut secured.

And the lower.

Then I thought it deserved an oil change. So I did that. 5 quarts GC 0W-30 (Castrol Edge) and M1-201 filter (I had 3 on the shelf).

Topped off the coolant. Started it up, no leaks. Nice.

I also adjusted the rear drums so the shoes drag a little. Hopefully that helps the pedal travel (it will).

Now I am going to play with my Bluetooth receiver w/ FM transmitter.

Road tested. Seems good. No leaks, runs great, brakes feel better, too.
