Anyone know if its the s52 or s54 z3m radiator that fits?

Still waiting .. :)

Early = 2 sensors 2 wires each
Later = 1 sensor with 3 wires.

[nando]

early are 2, late are 3. I think all B25s and setas are 3.

Is the thermoswitch on the e30's 2 prong or 3 prong?

I am looking at this thread:

http://www.r3vlimited.com/board/showthread.php?t=179952

and the first guy is recommending the 61-31-8-361-787 which has 3 prongs as such



While the guy on the second page says he uses part number 61-31-1-364-272-82 for his swaps but that part number is 2 prong...



Both operate at a nice 80c and 82c. However does the stock wiring utilize 3 prongs or 2 prongs?


The way I understand it is from 09/1987 they started using the 3 prong (61311378073) whereas upto 09/1987 they used 2 prong (61311364272/61311364273)?

The weird thing is that realoem and bmwfans lists all three (61311378073/61311364272/61311364273) for 'upto 09/1987'. So which one is it?


Edit: Seems as though the 2 pronged sensors only operate at one temperature. Still leaves the question, which e30's had the 2 prong vs 3 prong?

I think I'll buy one of these as I get closer to doing the cooling system, right now I need more important things first to get the engine done :)

Pm me and the hookup shall commenceth

that radiator looks really nice - what's the cost?

Hmm.. how have you solved the PS-pump rear support problem with the X5 bit? Correct me if I'm wrong, but isn't it so that the X5 bit doesn't have the support point - so I don't see the reason for using that as you can make the original mount "as good looking" while still maintaining the support point for the pump .. ?

Oh yes I do... and yes, minimum hassle is the theme of my build, lol!

Remote oil filter saves a lot of hassle :)



So I suppose you don't have PS .. ?

That looks very good indeed!

Two questions and one comment:
-In the bottom you're using OEM rubber mounts?
-Oil filter?

-One thing that maybe should be considered, is actually bolting that radiator somehow to the chassis of the car. I mean, e.g. E28 and E30 radiators have the two screws (with rubber) holding the rad. in place.
Now as the radiator is much heavier, should it be bolted tight "just to be sure", as I'd imagine that kind of water volume jumping around in confined space will quickly break e.g. that upper mount.. ?

Both top and bottom mounts are OEM rubber "biscuits". I had thought about making some tabs to fit in the E36 "slots" at each top corner and bolt them to the core support, just for extra security. I tend to agree with Justin that the upper mount isn't going anywhere, but we'll see. As far as the oil filter goes, I'm running a remote, dual filter mount, a front mounted oil cooler, the X5 adapter plate with AN 10 bungs welded to it and all AN 10 braided steel line and fittings. The dual filter mount is bolted to a bracket welded to the inner frame rail on the passenger side, where the AC compressor would be. The filters are twin Bosch screw on type filters and they hang right next to the oil pan...

Those upper mounts are pretty strong, I don't think any forces normally seen in a car would cause it to break, besides maybe a collision, in which case I'd rather the plastic mount break and save the radiator.. If you have that thing bolted down solidly, I'd be afraid of it breaking in a minor collision, leaving the car undrivable, or even cracking from chassis flex.

Holy crap, that's a hell of a stretch.

I think I'm going to try to find room to run the remote oil filter just so I can use this radiator.

Thanks for the writeup and pics.

Nah, it wasn't that bad, but those hoses do work for this application and they're spot on, as far as the molded bends and fitment, excluding the length disparity on the upper hose. You could always run the dual filter remote deal I'm running... more work and money, but no problems with room up top...

No sweat on the pics and such, I think it's a pretty killer setup and I don't anticipate any cooling issues...:D
