#2. Part 1 - Cooling System - from Mike Frank

Date: Mon, 6 Mar 2006 01:20:41 -0500 From: "Mike Frank" <mfrank28@insightbb.com> Subject: Part 1 - Cooling System The M3 is getting ready to come out of hibernation so it's time to do some maintenance (~70k miles, water pump & T-stat already replaced once). There's much to do, but I think I'm gonna start with the cooling system. I'll try to include P/Ns if I think I know them, this might help others in the future. Please correct me if you know they're wrong. 1. Radiator - Zionsville aluminum - heard good things, probably overkill. ($129 OEM Behr is tempting). 2. Water Pump - 11 51 7 527 799 (metal impeller, again). 3. Water Pump O-ring - 11 51 1 711 484. 4. T-Stat - 11 53 1 466 174, 80degC. 5. T-Stat O-ring - 11 53 1 265 084. 6. Aluminum T-Stat housing - 11 53 1 722 531. 7. T-Stat profile gasket - 11 53 1 740 437. 8. Upper & lower hoses - 11 53 1 708 499 & 11 53 1 726 344 (OEM), or pretty blue Samco Silicone. I'm planning to pitch the fan and use: 1. 80/88C fan switch - 61 31 8 376 440 (9/95 and up). 2. Fan switch O-ring - 32 41 1 093 596. Maybe I'll even add a pretty nut for the fan shaft. :) Is there anything else I should consider replacing - plastic overflow reservoir, cap, other hoses, etc? Tools: I think I can get by with a thin 32mm wrench and standard tools, yes? Or should I get something like the Victory Product Design Combination Pump Wrench, 01-0054? Any other tips appreciated. Thanks, Mike Frank 97 M3

#3. Part 2 - Belts & Pulleys - from Mike Frank
Top
Date: Mon, 6 Mar 2006 01:46:30 -0500 From: "Mike Frank" <mfrank28@insightbb.com> Subject: Part 2 - Belts & Pulleys I've got an idler pulley making a bunch of noise, so it's "belts & pulleys" time also. Of course I'd like to sneak in an upgrade if possible, so I'm thinking underdrive pulleys. It seems to me that all of the kits that underdrive only the P/S & water pump are very similar, no? I'd appreciate any feedback or recommendations. Regarding my noisy pulleys, the noise seems to be coming from the alternator area. I'm tempted to replace all of them. Deflection Pulley - 11 28 1 748 130. Adjusting Pulley - 11 28 1 748 131 (x2 for AC belt). Do I also need to replace the tensioners? Hydraulic Belt Tensioner - 11 28 1 717 188 (water pump & alternator). Belt Tensioner - 11 28 1 717 210 (A/C). See: http://www.realoem.com/bmw/showparts.do?model=BG93&mospid=47488&btnr=64_0831 &hg=64&fg=50 http://www.realoem.com/bmw/showparts.do?model=BF93&mospid=47486&btnr=11_1344 &hg=11&fg=18 Any advice would be greatly appreciated. Do I need any special tools (assume the fan is already off)? Thanks, Mike Frank 97 M3

I recently tackled R&R-ing my entire cooling system, a little later than I probably should have (119K on stock radiator, plastic t-stat housing, t-stat, water pump, hoses, etc.). Interestingly enough, all the pieced looked great and probably could have lasted for at least a few thousand more miles. But with the upcoming track season, and my paranoia that the water pump or the radiator would fail at any time, I think the peace of mind was worth it. This time I went with a Behr OE replacement, as by the time this one is up for replacement, I hope to be supercharged and will spring for the Al Zionsville piece. As for the thermostat, I think BMW has superceeded the old 80c one with the 92c. At least that was the situation when I was ordering parts for my S52. I'm not sure about the S50, but would suggest to check with whomever you order parts from. In addition, I also replaced the upper expansion tank hose the connects to the radiator (part # 17111723521) Mine was looking haggard and it was an easy replacement. Another item to get is high quality hose clamps to replace the old ones on all the hose connections. I used BMW coolant and DI water in a 50/50 mixture with 1 bottle of Redline Water Wetter. Make sure to buy the BMW OE waterpump with the new, updated composite impeller. A search of the list will net you both Geba and Graf failures as they are not as high quality and can fail within 10K miles (some even had shaft play new from the box!). I paid $89 from the dealership with my CCA discount and it certainly looks and feel like a quality piece compared to either the Geba or the Graf. As for tools, all I needed was the 32mm open-ended wrench for the fan clutch, a long screwdriver (to hold the water pump pulley), and various metric sockets and ratchet wrench to do the whole job. It was a very easy job and only took me about a few hours. Best of luck with the job. Drive Safely, Raza

Date: Mon, 6 Mar 2006 10:30:56 -0500 From: "Mike Frank" <mfrank28@insightbb.com> Subject: RE: [E36M3] Part 1 - Cooling System Bob, I was wondering the same thing when I was looking. I remember people using the aluminum ones years ago and I always thought it was a factory part, but you had to specify aluminum, kinda like the water pump impellers. I've also seen the aluminum ones listed with the factory P/M. From other posts/forums, it seems someone may be making these as an aftermarket part. Honestly I really don't know. I'm sure someone else on the list knows. Regarding the T-Stat temp, 80C seems to be popular with the fan delete mod. Some also say the lower temp T-Stats give more power at the expense of emissions, although there seems to be some debate on this. I was just planning on using the 80C T-Stat because it seems to have worked well for others. Thanks, Mike Frank 97 M3 > Mike, > > I just had the T-stat changed on mine.
