Tested and Ready 70° and 75° Thermostat

I'm calling that BS. Spal fan ≠ Spal fan. So I HIGHLY doubt that a a near 40 year old technology e24 AC fan moves more air (regardless static or in movement) than a powerful Spal fan (No Spal slimline fan). Also these are imo absolute durable, if you use sealed one. Many times proofed on trackday cars, that get a lot of abuse and heat.
Just for reference, on a FI S54 street car, electric fan conversion made massive difference regarding cooling, compared to the rubbish viscous fan, even it was renewed in the last 10k km.

how much power do the SPAL fans people are using on the e46 platform have?

Hi,

I don't recommend the 55C t-stat on daily driver
cars with occasional hard track days.

70C will give the perfect amount of heat in the engine/parts
for daily driver without triggering the check engine light.


The only and single electrical fan conversion I personally
would use is one from E92M3/E60M5. The fan blades size,
the motor size are all designed to work in the harshest
heat/enviorment, also the harness gauge.

Every single E46M3 owner I have seen converted to
Electrical fan is one from Spal.

The Spal fans are garbage in a sense of how much
air they can move...The Spal fan is worst than my 1988
E24 AC-Fan.

Anri

Those fans seem to be ridiculously over priced. I have no doubt as to their performance though coming from my X5M.

I didnt see your post and I have already purchased a 55C BMW OEM motorsport T-Stat.

I live in Florida where the car has NO issues getting Hot. I also plan to run a DO88 Rad along with my DO88 oil cooler and BW Oil Diverter Valve. I want to be able to go on 30 min sessions in Sebring and not worry about the car getting hot.

Would you recommend I keep the 55C and do this 70C Sachs Fan clutch versus electric or get your 70C tstat and the fan clutch? I will see if I can return my 55 TSTAT before anything else

Gentlemens,

I had very loaded month and have been away from
my upper shop. I work with shops in LA who are giving me
work and paying top $ for my brain.

A week ago came back and I got some flew combine with fever
and I have not be able stand up from my bad.


Appologies again the T-Stats have been assembled and ready
around 3 weeks ago.

Today I feel little better with no fever, finally.

All my LA customers are taken care of with the first batch.

Post office is closing at 4pm still have 2 hours.


Thank you.


Regards,
Anri

Sachs 2100 011 031

Unfortunatley it is NLA from Sachs since recently, but there are plenty still floating around Ebay and in stock at some retailers.

But it seems Sachs didn't manufacture these, they are simply repackaging them.

If you look on the images on rockauto for the BMW number 11527505302 you can see that there are several brands repackaging something similar to Sachs. Same part number on the little plate in the middle...

That's for posting that up. What's the stock fan clutch rated at? I might try this on the M3.

What is the Sachs part number for the 70⁰C fan clutch?
