Ghost Chip 188 Report post Posted August 12, 2021 Does anyone have a fan + clutch for a m52 that they’re willing to part with? Trying to avoid my overheating problems. Closer to Auckland the better. Also unsure if these come with a shroud or not. If it does then would be keen on that as well Cheers! 1 Quote Share this post Link to post Share on other sites
M3AN 4016 Report post Posted August 12, 2021 If it's a Japanese import (high ambient temp coolant system) then you shouldn't the clutch fan to keep temps under control in Auckland's climate unless you're constantly stuck in traffic on hot days. I run my M3 without clutch fan or shroud and did the same on my 328. The aux fan should be well enough. Not saying you shouldn't get one, just don't think you should need one. Under what circumstances is the car overheating? Quote Share this post Link to post Share on other sites
Ghost Chip 188 Report post Posted August 12, 2021 Oh, just when idling for too long. Found out that the electric fan is not working so will need to re-wire it - unsure at the moment what went wrong with the wiring (problem when someone else built it). Will be pulling out the engine at some point so that’s when I’m planning to put in the viscous fan as I saw that it’s better than an electric fan (unless you upgrade to an expensive one?) For reference this is for a m52 e30 by the way Quote Share this post Link to post Share on other sites
Blackie 510 Report post Posted August 12, 2021 I've not heard of a fan clutch causing overheating before. Usually when they fail they just over spin (i.e. don't clutch / fail safe) Quote Share this post Link to post Share on other sites

Blackie 510 Report post Posted August 12, 2021 Oh gotcha.That's a tiny fan. Quote Share this post Link to post Share on other sites
M3AN 4016 Report post Posted August 12, 2021 Yep, sorry, thought it was a stock e36 setup, ignore my comments above! Yeah, that's a tiny aux fan... but I suppose the size doesn't matter if it's not working, Clutch fan sounds like a good idea. Quote Share this post Link to post Share on other sites

Sorry to ask what may be a dumb question but apart from the obvious, what makes it different? Is it just because the aux fan on the stock e36 is bigger? And yup it’s a very tiny fan. It does work but just wired wrong so it’s not actually getting power to the fan Edited August 12, 2021 by Ghost Chip Quote Share this post Link to post Share on other sites

I originally meant your setup is not a stock (warm climate) e36 setup, I had incorrectly assumed it was. Quote Share this post Link to post Share on other sites

Oh what I meant was that what particularly would make your comment earlier negligible now that you found out that it isn’t actually a stock setup.

Blackie 510 Report post Posted August 13, 2021 Removing the viscous fan. We all assumed you already had one but it had failed? Quote Share this post Link to post Share on other sites

Would appreciate it if anyone has a viscous fan + clutch + shroud 1 Quote Share this post Link to post Share on other sites
M3AN 4016 Report post Posted August 13, 2021 Yes, Japanese size radiator, viscous fan, standard aux fan (the stock pusher is very high volume). If you can't get a clutch fan I'd get a bigger aux fan and use a lower temp fan switch. 2 Quote Share this post Link to post Share on other sites
Southerner 146 Report post Posted August 13, 2021 Pretty sure you won't be able to install a factory viscous fan clutch and fan. Mine wouldn't fit in my e30, and everyone on the internet has them removed as not enough clearance Quote Share this post Link to post Share on other sites
nick496 268 Report post Posted August 13, 2021 Yeah, I have tried to squeeze a viscous fan on my m52 swap, and would have had 2mm clearance with the radiator, and was concerned that under heavy braking on the track that they'd end up touching. Install would have involved removing the radiator, installing the fan, and then reinstalling the radiator. Some people have somehow made it work. But I, like most, have a 16in electric pusher fan on the radiator which works well. 1 Quote Share this post Link to post Share on other sites
Ghost Chip 188 Report post Posted August 14, 2021 I think some people have made it fit. This is a photo of one that I saw on FB. Car was in the last caffeine and classics I think. Quote Share this post Link to post Share on other sites

Southerner 146 Report post Posted August 14, 2021 I dont really see why you would risk it and go a viscous fan. A decent sized radiator in there or an electric fan on the front is the better solution Quote Share this post Link to post Share on other sites
