So this was a first - got an alternator workshop error. Never seen that before. And my battery was not being charged, nor was any voltage being output from the alternator. So I replaced it with a junkyard alternator last night. I also couldn't wait for the replacement fan I ordered from CascadeGerman, so I put in a junkyard fan which worked flawlessly. Even got a spare. I don't know if I should be satisfied or not, but AC now gets down to around 44-45 at idle with outside ambient air in the 83-87 range (at around 70% humidity). Driving, I got it as low as 42 and as high as 54, but the car stays cool now.

On mom's 2005 wagon, the radiator fans won't come on and I can't figure out why. The AC compressor engages manually, and the radiator fans also come on manually, but I tried a different high pressure control valve, 2 different fan control modules, and checked all the fuses. I started losing patience checking things electrical, so I'm giving up for now.
Try swapping the high pressure switch with another car.

Helped the friend of my wife's 03 wagon today. Had 16955 for brake light switch intermittent... Cleared the code for now, will order a switch. Found that all the brake and running lights were out in the back end. Had one blow up in my hand too, luckily it didn't cut me. All new bulbs and down the road she goes.

Maybe hold on the switch.
The bulbs out may be the only thing wrong.

Filled it up this morning. $80.81 @ $6.249 a gallon at Citgo. Seems to be the cheapest around. I did, however, just barely get 50 MPGs on that last tank, a personal best (usually around 45-47), so I wasn't too upset. Mostly normal driving.

Filled up the Suburban yesterday at Mobil. Pump cut me off at $125, so it didn't get filled all the way. That was at $4.949 a gallon. Probably 15 MPGs on that pig.

Works out to $0.33 per mile on the Chevy, and $0.12 in the VW.

Also mounted the JETTA and TDI badges on the trunk lid.

Spray cleaned the 23 year old N75. Fixed light throttle stutter and light throttle steady state warp field collapse.

About to swap N18 for N75 to see if it goes away even though the N18 is also 23 years old.

Yesterday, was backing my Roadmaster out of the garage, Jetta parked in the driveway but behind the 2nd stall of the garage (similar to the picture below). Checking mirrors, going slow, etc - CRUNCH (sigh...)

Broke a bunch of plastic on the right side mirror of the Jetta. It didn't come completely off, but was loose/wobbly. About 20 wraps with electrical tape over the joint holding most of the plastic bits together and at least it's not all floppy anymore. That will last long enough until I can get a replacement from the spare parts bin.

While I'm frustrated about the mirror, I'm not too sad because it means that I'm driving my Roadmaster that I spent the last 8 years working on...no damage to the Roadmaster :)

Ended up replacing the passenger side CV with a new GKN on the 2000 Golf, replaced the upper radiator hose with a genuine VW from idparts (so like 95% of the engine cooling system, including the fluid, is all brand new). Put on an Evolution Atlas kidplate obtained from cascade german. Replaced the hood latch assembly on the front, put on a racepipe (ASV delete) from darkside, and finally RSSR tail lights from Korwerks. I only have a single rear shock that needs to be replaced (worldpac sent me 1 B6 and 1 unknown/wrong part). All that's left is the rear main seal and clutch. I'm holding out on that, because I'm still undecided if I want to install an LSD or not.

Last night - checked out my fix-n-flip 2002 Beetle. Looks like the head's coming off. Cylinders 3 and 4 have both cracks on the pistons and bent rods. Oddly, cylinders 1 and 2 look okay. The oil pan area smells like burnt oil. A friend suggested a blown turbo, but we shall see.

And then not mk4 related, but I'm hoping to change the starter on my 1995 GMC 6.5L diesel, so I can get it the hell out of my life. I only have room for Fords and VWs in my life right now LOL!

Just make sure you have the little bracket on the end or bad things will happen.

Sunday was steering rack day. All told it took me about 5 hours total. No issues. Had to go to Advance and get 2 quarts of that Pentosin CH11S fluid in green can-$37.99/qt o_O . I did 2 separate online orders, 15% off and $10 speed perks for each so it came to $25.69.I only needed part of 1, as I already had a partial quart. I centered the steering rack, it is 3 complete revolutions from lock to lock, so I made 1-1/2 turns before installation. Put some grease on hard lines to cut down on future rust. Installed heat shield before putting rack back in car. Outer tie rods were a little tricky. I counted turns coming off, but the old ones(TRW) were just a little longer body than the Driveworks ones from Advance. So I just set them to # turn ins from old rack, then I set new rack and old rack side by side to compare. Got them eyeball close before reinstalling rack in car. Once installed, lost count how many times I turned wheel lock to lock to bleed with car off. Thought it'd be good, topped off and started car and did a few more lock to locks. Lots of foam/bubbles. Next day I re-did bleeding. I did eyeball alignment, checked how much tire I see on each side from top. I adjusted right side 1 turn. Tightened everything up and took for a road test. I was shocked to see the steering wheel almost centered and no pulling side to side. I'm still dropping it off for alignment check tomorrow. We'll see how close I was....

You mean on the 6.5? I did. Working with that truck is a PITA, but I did get the starter replaced and got it to crank up (with help from my 7.3L in high idle, to get my crappy Walmart Neverstarts going).

Question that's semi-TDI related - one of my fuel return lines is leaking. Any idea if it's the same size return line rubber as on a TDI? I have plenty of it and it would save me considerable trouble, though I'm not sure yet how I'm going to get in there to do it (it's the second from the last injector on the passenger side).

Yeah, on the 6.5. Lots of people leave them off, but it can cause problems with that.

Well I’ve been noticing a slight growling noise from the rear of the car recently, seems loudest around 60-80 km/h. So this morning I jacked up my rear wheels and tried wiggling them back and forth, up and down, well that all seemed good so I gave them a spin. That also seemed fine, at least at slower speeds, but if I spin the driver’s side up as fast as I can by hand and feel the spring there’s a slight vibration and faint growling noise so I guess I get to do rear wheel bearings now...
Question is, should I replace both sides or just the one that’s making noise?

This is only personal opinion, but I do everything in sets. Front wheel bearings, rear wheel bearings, etc. I can only imagine if they were put in at the same time that if one is going, the other isn't far behind. If I was strapped for cash then maybe I'd just do one. I see it kind of like rear axle beam bushings. You wouldn't want to do just 1. It could potentially heighten the issue on the other side (cause premature wear to the newly installed side), or push that wear somewhere else.

I had to replace one rear wheel bearing recently due to a shop monkey cross-threading one of the lug bolts and it stripping out.
I just replaced that one - not for cost reasons, or lack of time (it was up on the mini-lift for a couple weeks)....just figured there was no need.
YMMV :)

One. When my front bearing went bad, I only changed that one, and the other side is still good tens of thousands of miles later.
I think this is mostly personal preference. I replaced one on the 2002 Golf (because I put on a new axle after I hydroplanned in January). I bought a second and was going to do both, and then decided against it (because the labor was high, since I haven't figured out how to do bearings yet), and for the same reason @turbodieseldyke suggests.

Thanks for the input everybody! Not sure what I’ll do yet, I did both front bearings shortly after I got the car, so if I do both the rears all my wheel bearings will be new, and my OCD likes that idea lol but I’m not sure I want to spend the money.

Another question, I normally get my parts from Roseland here in Canada, and they only have the rear bearings in two brands, Topran ($65) and FAG ($112). I’m guessing the latter would be the bearing of choice here? I’m not sure I’ve heard much about Topran, and that price makes me wonder about quality.

In my experience wheel bearings on these cars tend to suffer pothole damage long before they wear out, which is why replacing two when only one is noisy is usually a waste of time and money.
Yeah I had to replace the caliper on that side when I did brakes as it was apparently seized, couldnt get it to retract, so I’m guessing that brake was dragging and overheated the bearing.

What did I do to my mk4 today... I learned what a bent piston looks like!
This is actually a project car I bought to fix and flip, but yeah, definitely gonna be more involved. Someone wanted to buy it for $1200 as-is. I almost wished I sold it, but... I really want/need the experience of rebuilding an engine, and it's been on my bucket list for over a decade to rebuild an engine by myself.

Fag. No question there. You get what you pay for!
