You are in the Oldsmobile Aurora
What is this discussion about?
Oldsmobile Aurora, Sedan
#2 of 474 Not much here...
Jan 29, 2002 (10:30 am)
So I figured I'd add something. I definitely wash my car at least once a month, but try to do it more like once a week. I wax it about once every month-two months. This includes the winters. Fortunately the Washington D.C. area has weird enough weather that you get the occasional freaky 65 degree January day.
I changed the oil after the first 800 miles because there are significantly more metal bits deposited in the oil in the first few hundred miles on an engine. I use two quarts of Mobil 1 and the rest regular Mobil. I am trying to find the ACDelco Ultraguard filters (Pep Boys says they don't carry them anymore) but will use regular ACDelco Duraguards until I find them.
I plan on changing the tranny fluid after 50,000 miles despite the "lifetime" claim. Once the fluid gets burnt, it is too late... Besides, 50,000 miles is better than 30,000, so I'm still happy with the extended life. I'm not sure if I will wait 5 years on the coolant... Maybe...

I found some interesting info on why Pep Boys has stopped carrying ACDelco Ultraguard filters. None of the Pep Boys near me carry them. Apparently people were swapping Ultraguard filters with the Duraguards. This way they check-out with the Duraguard box and pay $2.50 for a $9 filter. I'm not sure if this is true, but it sounds like it could be... I just thought it was interesting.
#4 of 474 Ultraguard update!!
Feb 05, 2002 (8:19 am)
I emailed ACDelco about the Ultraguard filter for the Aurora because I have had a heck of a time finding any, and because their website doesn't list it as a part for the Aurora. If you search for oil filters, only the PF58 shows up for the Aurora. If you check the vehicles that the PF58 fits, it will show Auroras and Cadillac Northstars and the Blazer. If you check for the vehicles that the UPF58 fit, it only mentions the Cadillac Northstars.
So because of these two things I decided to email ACDelco to see what was up. They responded that they are discontinuing the Ultraguard filter. So that sucks... I sent a reply because I would like to know if they were discontinued because of performance problems or because of sales problems. I'll let you all know what they say...

According to ACDelco, the Ultraguard Gold line of oil filters were dropped because of poor sales, not because of any performance issues.

Thanks for the heads up. I have two UPF-58s in my stock. I'll try to buy some more before they disappear (although I may already be too late).
#7 of 474 classic spark plug replacement
Feb 10, 2002 (7:16 pm)
Recenty my '97 with 73 000 miles is taking longer to start, intermittently. I'm thinking it may be time to replace the spark plugs and maybe spark plug wires.
My problem/question: Which plug? My owner's manual says AC 41-929; service manual says AC 41-900; emissions label on radiator cover doesn't specify.
What gap? Owner's manual = 0.050; service manual = 0.050; emissions label = 0.060.
What is correct?
#8 of 474 Plugs and filters

I don't think it is too late to get the Ultraguards. I managed to get three of them into my local Olds dealer. However, the Olds dealer is the only place I could find them.
As far as the spark plug gap, I would lean towards the emissions label because those are usually the final word. However, you might try removing some plugs and see what the gap is. If they are worn and the gap is still only .056 or something, then go with the owners/service manual.
#9 of 474 Maintenance Items
Mar 24, 2002 (10:53 am)
On my 1995 Autobahn, I changed the trans fluid at 90,256 miles. In the fluid were many small metal pieces. The filter and gasket are reuseable, simply clean them. I replaced the fluid with Mobil 1 Synthetic Trans Fluid. Yeah it costs a little more but it has never let me down.
It almost goes without saying that I also use 100% Mobil 1 motor oil (10w30). Additionally, I use STP Oil Treatment as well as STP fuel system cleaner. I change the oil every 7,500 miles. I have no oil leaks.
I have also added Slick 50 because I had good experiences with it. The engine idles smoother and revs very easily.
The ignition switch had to be replaced at 70,439 miles, new plugs and wires at 84,515 miles.
#10 of 474 coolant pump belt
Apr 01, 2002 (5:40 pm)
Has anyway replaced an Aurora classic coolant pump belt? At 75k miles mine shows many cracks and feels brittle. I plan to replace it soon and have already purchased a Dayco replacement. The service manual procedure seems very straightforward. However, when I examine the existing setup, I cannot see how the belt can be replaced without removing the tensioner (which doesn't look like an easy task). As I see it, the problem is there is not enough space between the tensioner and the valve cover to insert the replacement belt.
