It's the one in the for sale section in NJ. Needs some work, but nothing I can't do. Had a quick question. Don't have the car in my possession yet, so I can't inspect any closer, but which radiator do you typically use when doing the swap? I'm going to assume the 6cyl one, for the improved cooling capabilities. It may have a leak, so I am pricing them out prior to the car being home, so I know what to order if I need to. I have to re-mount the rad anyway, it's got about 20 zip ties holding it in now, so If the 6cyl needs a little bit of customization, that's alright with me, worth the added cooling. I searched, but don't have the time to read everyone's build threads to find the info. The sticky for needed items does include radiator, probably confirming my thought I need/have the 6cyl one, I just want to make sure. Probably going to have a bunch of questions, got a LOT to learn with it, but it's gonna be fun | | | 04-28-2008, 02:00 AM | #2 | NOBODY F's with the Jesus Join Date: Oct 2006 Location: Ventura California Posts: 7,824 | Might as well get a 6cyl radiator. They're cheap. I bought a Behr radiator off ebay for 125 shipped. Might be a couple bucks more for a larger one, but well worth it IMO. Quality was as good as the OEM one that I pulled out. While you're at it you should replace the hoses, clamps and plastic coolant lines if they haven't been replaced already. It would really suck to get a new radiator installed/filled/bled and later find out that you're leaking from somewhere else. Good time to replace the thermostat and water pump too. Everything can be sourced for about 200 bucks. I know cash is tight right now, but save up for a couple of weeks and get it all done so you won't have any problems later. Edit, can't remember if your new car has the fan delete mod. If so DEFINITELY go with a 6cyl radiator and remember to get the lower temp thermostat. Search "fan delete mod" or FDM on pelicanparts or bimmerforums for some good writeups. __________________ 4 MORE YEARS BABY!!! | | | 04-28-2008, 02:09 AM | #3 | Senior Member Join Date: Nov 2007 Location: Rocky Hill, CT Posts: 1,065 | Quote: Originally Posted by cooljess76 Might as well get a 6cyl radiator.

I think you're the guy that wanted pics of my scout? I'll post them in the lounge area. I figured the 6cyl would be a good upgrade, just wanted a second opinion. It does have the fan delete, and i'll be throwing an electric fan on obviously. I'm not even sure if the rad is bad, but I like to plan ahead. And after half-assing some things on the truck in my past, I'm a FIRM believer of saving up, and doing it right once. I was planning on getting the colder temp t-stat, he said it was acting wacky, so that's on the list. thanks again | | | 04-30-2008, 05:04 PM | #4 | Senior Member Join Date: Jan 2006 Location: Cincinnati Posts: 890 | The M3 radiator has an extra row of cores (cooling tubes) in it. I believe the stock 6-cyl radiator is a 2 core and the stock M3 is a 3 core. __________________ SOLD!!! 1999 332ti //M Sport Titanium Silver M3 S52 3.2 I-6 Engine, M3 Clutch w/ ti Getrag Trans, Z3 3.15 LSD medium case diff and half shafts, OEM Hatch Spoiler, Eurosport HP Underdrive Pulleys, FDM, 17" DS1 rims, M3 Front Struts & Springs, M3 Instrument Cluster, 3-spoke //M steering wheel with tri-color stitching, SSK, CCFL Angels in Depo projectors with 5k HIDs | | | 05-01-2008, 12:01 AM | #5 | Senior Member Join Date: Nov 2007 Location: Rocky Hill, CT Posts: 1,065 | Quote: Originally Posted by campaiar The M3 radiator has an extra row of cores (cooling tubes) in it.
