So I finally finished most of everything. What I did get done over the last week:
Cooling system overhaul using TMS' kit (link: http://www.turnermotorsport.com/p-19...328i-330i.aspx).
The kit came with pretty much everything. I used an assortment of guides to help along the way, but these were the most relevant:
- http://www.bmw330ci.net/maintenance/completecoolant.php
- Several from Pelican Parts, but mostly this one on the radiator: http://www.pelicanparts.com/BMW/tech...eplacement.htm
As I said earlier, I've never really wrenched beyond doing spark plugs, oil change, and installing the OEM aux input cable so I didn't have a whole lot of experience. I didn't think it was too bad overall, the biggest issue I had was the bracket attached to the radiator that attaches to the expansion tank. They really should include that part, personally. Otherwise the only other issue was fitting the upper hose to the expansion tank and radiator inlet, it required some serious force.
Other maintenance:
I used TMS' maintenance interval kit (http://www.turnermotorsport.com/p-10...e-package.aspx) and picked and chose which parts I needed. With that kit I did the following:
- Pulleys (AC tensioner, idler, tensioner): Easy peasy. I used a breaker bar with the proper Torx bit and it was simple as can be. Used a couple of YouTube videos and DIYs to help me (some of said videos: 1. https://www.youtube.com/watch?v=A_sL9NLj5f8 2. https://www.youtube.com/watch?v=PA1PQ6AyiNc)
- Belts (serpentine, AC): Easy as well, pretty much supplemented the pulley replacements.
- Transmission fluid: Decided to use Redline MTL instead of the suggested options from TMS since I had read a bunch of different DIYs/maintenance threads that suggested MTL, and it's what my father uses in his E39 540i and it is buttery smooth. The fluid change itself was easy enough although I was confused when the DIYs I was following called for a 17mm hex but I was confronted with a T50 Torx bit. Found out later than many ZHP owners have either Torx or 8mm hex bolts for the fill/drain plugs on their transmission. At any rate, followed a few DIYs, this one was good for pictures: http://www.impee.co.uk/transmission_fluid_change.htm
- Differential fluid: Proved to be a bit of a pain in that I did not have the right tools for the job. It calls for a 14mm hex socket but buying a 14mm hex socket alone are pretty spendy so I opted to buy a 14mm bolt and two nuts and use a wrench on the nuts. Unfortunately, I managed to bend the bolt and the fill plug hadn't budged at all. I broke down and bought a bunch of 1/2" hex sockets through Amazon so that delayed the drain until today. When I finally did do it, I was surprised to find no crush washers. I had gotten some through my kit so I threw them on there, but surprised there weren't any to begin with. I used the prescribed Redline 75W90.
- Spark plugs: I figured the spark plugs were an easy swap and since pretty much everything but the motor oil was 10+ years old, they were due as well. Swapped them out quick as mentioned earlier, no problems. I forgot how big the coil packs are!
- Air filters: It was time. Simple enough to do, no DIY guides necessary. Both were dirty and needed replacing.
- Oil and filter change: It was actually a bit early (oil had been changed about 3k miles ago) but it never hurts to start fresh. Pretty quick and painless, plus gave an excuse to swap out the oil pain drain plug for a magnetic one.
This cold has really got me down, I felt pretty awful just getting the car off jack stands tonight and filling/bleeding the coolant. Even so, I think I bled it well enough. I drove it around for half an hour and the car warmed up and heat came out of the fans no problem. The more uplifting thing is that after all of this work there were no error codes, no visible leaks, the temperature gauge was pegged dead center when before it had trouble heating up. It felt good. As a result of a lack of definitive DIYs I'm leaving the power steering flush to the mechanic, which I have to go to anyways to get an alignment. While I'm there I plan to do a brake fluid flush and CDV delete, as well as see if they'll put in my BMW Performance grills. I know I could save money and do some of that myself but this cold is killing me and I'll save those things for a later learning experience (and I don't trust myself with the grills, I've broken tabs on 3 separate sets on my old car).
So all in all not too shabby! I think I saved about $1,000-1,500 when looking back at what a similar job cost me on my previous car. Still many other things to do, but none are of an immediate concern like the items I got done. My apologies for the lack of pics, my illness made me just want to get the job done quicker and completely disregard photographic documentation.
A few pics I did take:
In the process of removing the coil packs
All removed
All laid out, old spark plugs included
Out with the Bosch in with the NGK
Got it up on jack stands after
Draining coolant
In the process of replacing the belts and the pulleys
New AC tensioner pulley assembly in place
Odds and ends:
I received an OEM ZHP knob (part no. 25117896886) in the mail from ECS Tuning and swapped it out for my current one which had bubbling under the icon and part of the leather was ripped/scratched. I also attempted my E90 mirror retrofit using this guide (link: http://www.bigpatsfans.com/mirror/compass.htm, EDIT: that link is down, this guide seems thorough: http://forum.e46fanatics.com/showthread.php?t=1097788) and the clown nose will light up when the car is locked, but it doesn't have power for the compass, the autodim, or the HomeLink. I'm not sure where I went wrong or why it's not working. I'll have to figure it out soon, but does anyone have any insight?
