Finally got to drive the SOB after grappling with the t-stat issues. It finally opened. I'm thinking I need a puller fan on the other side of the rad, as the temp just kinda hovered between the halfway and 3/4 mark. When the SPAL fan kicked on, it brought it down to half way, but it didn't stay on long enough or kick on fast enough for my liking. The brake booster is now a vac leak, so I said screw it and ordered an E92 booster and master off ebay, along with the rest of the parts needed to relocate the reservoir. $100 all in, which I believe is worth it.
Rack still needs to be bled.
I did mount the diag port and the coil pack plug with some zip ties.
I also wired up my caddy horn I had laying around. Sounds pretty sweet.
I need to mount my expansion tank, but I'll wait until I remake the brake lines for the new booster.
Engine covers hopefully here by this weekend. Really ready to button this thing up and driiiiive.

What are you running for the fan switch? I searched and didn't see anything.
I run I think this same SPAL fan and a lower temp (88deg?) mercedes switch (that I can't seem to find the pn for right now) and don't see over 95deg while heatsoaked at idle.
All wiring is with the old high speed aux fan wiring like the "Official Electric Fan wiring thread!" shows. (except the switch he gives the PN for is supposedly actually a 91degC switch)Originally posted by priapismMy girl don't know shit, but she bakes a mean cupcake.Originally posted by shamesonUsually it's best not to know how much money you have into your e30

Give the dash a smack and see if the coolant gauge goes lower? The gauges are sketchy at best after 30 years lol.
My fan usually runs for less than a minute also.

Ok so it stayed much cooler after letting it sit overnight and filling the expansion tank back to the cool mark. Some air came out when I opened the cap. Will continue to monitor and bleed. I got the rack bled, still binding a bit, but way better than before. I also made a bracket to mount the PS reservoir. I’m using the stock E30 reservoir and bracket with my additional custom angle bracket. Just didn’t like where it would mount on a stock E36.

I swapped in the E92 booster today. Pretty easy. I just shaved the clevis pin to remove the collar. I used the old E30 clevis as a spacer in the middle. Clip on one end, and spring on the other. Easy peasy. Plenty of clearance with the booster. Also stops like a champ. Also found another sunroof visor at a junkyard. I liked the purple more than the blue one the car came with. It was polished and looks great! Sent from my iPhone using Tapatalk

Well the lovely camshaft position sensor code came back. Ordered a brand new Siemens unit from Pelican parts. Hopefully this fixes the problem. Still need to resolve my MAF code, but I'm not too pressed to fix it as of yet.
I was able to get my licence plate blank sorta kinda mounted. The sides "billow" up and out a bit. Might take a heat gun to it or try some epoxy and clamps to keep it flat.

Hopefully I'll receive my engine covers tomorrow!

Was able to mount my VC cover. Still waiting on my camshaft position sensor. Also need to figure out a mounting solution for the fuel rail cover. Not a huge priority. Received my new clutch and brake pedal pad. $5/piece on FCP. Makes me wanna repaint my pedals, they look atrocious. I also received my coolant level sensor which thankfully was the problem. I really didn’t want to retrace the sensor wires back over to the passenger side. Just brake lights now. I received what I had hoped was everything to get the A/C system back in shape. I already have the custom crimp-on connectors that I need to put in the hose. I also have both sets of hoses (E30 and E36) ready to modify. I need to confirm which hose goes where (was told the E36’s connections on the compressor were reverse to the E30’s connector). Will need to wire in the switch. Sent from my iPhone using Tapatalk

That cam sensor problem is super common. I think any M52 that hasn't had the sensor replaced is in similar shape. All of mine are the same or very close.
I took the best one and potted the whole boot.Originally posted by priapismMy girl don't know shit, but she bakes a mean cupcake.Originally posted by shamesonUsually it's best not to know how much money you have into your e30
