Urgent wheel replacement with junkyard rim and ended up replacing all four tires yesterday...

The Michelins came with the rims and were due for replacement by summer anyway.

I needed 1 wheel that fit to replace one that got damaged. A set identical to mine was on Craigslist nearby for $400, but they just sold the day before. They looked great too! I got one from the junkyard for $100. Not pretty, but fits and is at least same style.

I ended up with Cooper AT3 4S 265/70 R17. $220 each. Nice tire. Great tread, but good road manners on the highway. 3 Peaks rated for severe snow. Pretty quiet for AT tires.

Here is the crappy junkyard rim...:( The other three were well cared for and looked great for their age. Maybe the ***** one will clean up good enough, so it looks good when you squint.

Anyone in MA/CT have this kind (from 2010-ish), in similar condition as my good ones, sitting in a garage, doing nothing for you, let me know. I might look to do something to get this ***** one off in a month or two.

I will just have to live with what I have for a little bit.
They sell a rim cleaning chemical at O'Reilly's. Can't recall the brand, but it's with all the detailing stuff. Works like magic. Spray it on, let it sit. Spray on again then pressure wash it off. Spray it on again and then take suds and a sponge to it, she'll look like new.

Finally got the Yukon in the audio shop this week. Got the stinger heigh10 media receiver, 1000w amp, morel ultra mkii components front and rear, finished off with an mb quart discus 8in sub in the stock box. Worth the 3 month wait on the install appointment, install is super duper clean.

I was unfortunately having voltage drops that started right before my appointment, so I spent this morning putting in a new 175amp alternator, tensioner, and idler pulley.

My grounds are pretty corroded though, and I have the wires, but I’m not yet motivated to get my hands that far into the engine bay. Will save for another weekend.

The voltage drops when feathering the throttle in traffic around town are thankfully gone now with the new alternator. Big time anxiety in grid lock city traffic. Glad that is taken care of.

After I put on the new parts I went out for a test drive to Snoqualmie pass for some pancakes with the mrs.

Looks like a Delco box for the alternator. What part number is it for 175a? Did you have to get a different size belt? Thanks.

This made me laugh when I really wanted to cry...
20230112_085058.jpgWhile on the side of the road with a destroyed rim, flat tire and brake caliper issue the other day I was waiting for flatbed and noticed this:

The temperature display on the mirror reading 70-71 F... I am in MA and it was snowing!

Normally, it seems to be very accurate all the time. Today, it seems to be back to normal. It was reading 30 F when I left the house this morning, which was correct. Maybe because I was parked and idling for a good hour...

It’s part number 3351092

Fron my understanding this is made to the size spec of the stock ad244 130amp alternatir. It does require a longer belt if you have the ad230 105 amp one.

TBH even after removal I can’t see another way of identifying the styles alternator I had without measuring things, which I didn’t do. And, the new belt looked to be the same length when I compared it. So, I don’t know if I needed a longer one.

In any case, since I didn’t know, I just got the belt/tensioner/idler kit for the 130amp style alternator I was getting. That was part no ACK060930 (belt alone is 6K930)

That link say it's a 145a alternator. That's what I have in mine...got excited when you mentioned 175a as I've not seen an OEM one with that rating. No worries, there are other makers of higher rated ones.

Put in junkyard e-fans with factory harness (thanks @select127 ) and spare PCM tuned by me with VCX Nano, bench harness, TunerPro, and PCM Hammer. After a snafu trying to use the factory ground location (i didn't sand off the paint, so moved from right body mount area to left body mount) they work! Well, work when I ground either wire on the harness, work when the A/C is on, work via Tech 2 commands, but not just idling/driving around. Took it for a spin and nada. Got home and decided to check what I programmed them to come on at: 205*. My cheapo obd bluetooth said ECT was 204.9* as I let it idle in the garage.

Hrmm...either need to go romp on it and see if I can get the temps up or program lower activation temp or not worry about it!

So much moar room under the hood! Had the harness for almost 2 years and fans for a year. My wife hates when I accumulate parts for projects.

Edit: apparently, i like to use "Well" to start sentences. Removed superfluous instances.

Thanks, I was just about to ask this same question. I assume since you are referencing 105A and 130A alts that this 175A alt is the 4 pin 00-04 style, not the 2 pin 05+ style. I was looking at a 175A at Rockauto, if so this might be what I was looking at.
