My Ride: 323iT, 330Cic
The 323 touring is the car being tested below.

I will note that I've had the whole cooling system overhauled in the past year finishing with the radiator (had a leak near the expansion tank) & thermostat (working fine; but last piece to change and since the radiator was coming out...) replaced this past June; but noting that all these parts were replaced betwen 104000 & 112000 miles on the car which seems to be normal as a replacement timeframe. (The wagon was surely not in the best shape when I got it at 92000 miles and I've put in a good amount of effort to get it back into shape.)

Using the OBC function 7.0 (coolant temp), on the way home today in some stop and go traffic the external temp guage was reading about 109F.

Once the car warmed up (didn't take long) I was showing anywhere between 93-98 on the cluster readout. All told the trip was somewhere around 35 miles and about 45 minutes; though I did have to make a stop for about 20 minutes about halfway in.

I'll be trying this test again this week while on the highway on the way home (full 30 miles, no stops), again expect the outside temp to be reported 110F. I did take it on the highway today and it was reading around 91; but by the the external temp read 104F.

Now... I didn't see one; but is there any OBC or other test I can use to check the temp of the tranny?

Hahaha, I was beginning to wonder since I have a Manual tranny and starting to wonder what they are talking about

OK, managed to run this test again, this time around 30 miles all highway, average speed 70+. External temp gauge was showing 110F at the start and when I got to my destination had "cooled" down to only 106F.

The temp stayed between 91 and 93 on the cluster readout.

So, while this isn't the worst days with regards to temp out here, it's still plenty hot. Given that, I'm not seeing anything to be concerned with at least as far as coolant temp goes.

If there was a test for the tranny temp, I'd happily run that.

OH... and of course for both days, I had the AC running, set to 70F for the full duration of both trips.

Hope this helps anyone considering this swap.

I'm think of trying it on my M. Does anyone know if the connector is the same.

I'm not sure about the tranny temp but there is a test for the oil temp.

The aux fan connector appeared to be the same as the connector that my old 330's electric fan had

I really wasn't paying attention to the time, I was more worried about mosquitoes eating me alive. I'd say like an hour to an hour and a half.

Thanks for the DIY write up... very glad to not have the car sound like a city bus!!

It ended up being so much easier than I thought. Budgeted Friday evening and Saturday for this, now I have my whole Saturday free.

As a side bonus, it turns out the huge gap between my front fender and my bumper was due to the bumper not being slid onto the side brackets, which I noticed when I was taking the bumper off. A little adjustment to the brackets and a proper install and I've got a nice bumper fitment now!

Just did the swap today. A piece of advice from my experience: be careful when trying to pop the fan clutch nut loose, I split my thermostat housing whacking away at my 32mm wrench. Added bonus: my a/c works like a champ now. Before, I would have to be driving at least 30 mph for my a/c to blow cold air, now even sitting in a parking lot it gets cold. And no more ac/clutch fan lag off the line!

Excellent guys, glad you are getting additional benefits. Ribri, for you probably the aux fan was not working anyways, BUT keep track of the electric fan because maybe the controller for it might prevent it from working properly.

No, the bumper has to be removed.

Just did this to my ride but when i tested the new fan it would not come on. I checked my fuses, good, i even cleaned them up a bit just in case. checked for voltage at the plug, good. im going to replace the thermostat on my lower radiator hose and see if that fixes it. If not then i guess i will have to search the forurm and see what else i can do. Wish me luck, im really hoping its just my thermostat.
