Cooling your m30

[LowR3V'in]

I looked at acouple logs showing it would normally be about 187f.
It would go up 200f when I beat the shit out of it and go down to 183f when I let it wined down in gear (fuel cut).


The rating isn't like a switch. It slowly opens and closes.
and the radiator isn't 100% efficient. So. Allot of slop in the real world 1 step colder works great.

What Mishimoto model number/part number are you running?

Im using the regular e36 mishimoto radiator. Don't have a part number on hand right now

I understand that it's not a switch, but I am still foggy on how a 70C thermo would provide any more cooling capacity than an 80C. Yes it opens earlier, but it doesn't open more.

And it fits? Damn, my distributor cap and a/c compressor are like 1/4" from the e28 535i radiator; I couldn't possibly fit a thicker one.

i'm in the same boat. Anyone got an overhead photo of an e36 radiator with their m30 swap?

Yessir

i know we're talking about mm's here but it sure does look like your build has more breathing room up front there.

the e28 535i radiator is pretty thin as it is and I've got 4-5mm between it and the distro.

Care to measure the depth of your mishimoto rad when you get a chance?

What position do you guys have motors?

This is my radiator

i've been under the impression that i'm in position #3. Comparing it to other cars it looks more like in between 2 and 3.

thanks for the link, now i need to go measure mine when I get home.

I think the cooler thermostat just gives the system more headroom - ie. the thermo opens earlier, then you can run a lower temp fan switch so the fan kicks in earlier - this keeps the whole system further away from the tipping point when it goes into an overheating situation. As I mentioned earlier - this was a factory option in hot climates, so BMW thought it was worthwhile.

The e36 radiator looks a good fit there - I'm with you Corvallis, I don't think I could fit one in my car and supposedly I'm in P3 with e30.de mounts, but realistically I'm probably closer to P2.

I'd love an all aluminium mishimoto radiator.

[ThatOneEuroE30]

I'm using Qbang mounts.

[glnr13]

i measured from the front of the radiator that touches the support to the back fins and it measures just about 1 3/4". I'm now considering that mishimoto radiator as my next replacement.

Can you get your power steering belt on though?

Yea I can. Only thing i cant do is replace the alternator without lifting rad up to slide lower bolt in and out.

I ran into that same issue with that lower bolt when I replaced my alt last year. I flipped that bolt around in case I'm ever in a pinch and need to do it again quickly on the side of the road.

I tried that but wouldn't work without removing oil filter so just left it as is
