Maybe a stupid question here, but are these two openings feeding small radiators? What are they for? Also, are there two central rads?

The two you've circled are "remote radiators" for cars with the MSports (and some sportsline) vehicles. See http://www.realoem.com/bmw/enUS/part...BMW-340i&mg=17

The bottom center is the A/C Condenser. The upper center is the main radiator.

The reason for so much cooling is that the Intercooler is water-to-air rather than air-to-air.

Thanks. So, what do these "remote radiators" cool?

Coolant, what else? Look at the diagrams on the link - hooked to the main radiator and coolant pumps.

If you have the track pack, you don't get fog lights, That's because oil coolers take their place. I'd guess at least one of these is for cooling oil.

You would be wrong. Recent BMW engines use a water-to-oil cooler.

That's one reason (as I already said the charge-air cooling is the main one) that there are so many COOLANT radiators.

Look again, genius. I posted the link, all you have to do is actually follow the link to discover it's NOT OIL.

wow, someone has some anger issues.

From the looks of things that appears to be a pre-LCI F30 M Sport..

Which means:

-Top center (immediately behind the kidney grills) is a Auto Trans Cooler (Air-to-Oil);

-Bottom center (immediately behind the lower grill opening) is the Air-to-Air Intercooler;

-Behind both of the above is which spans the whole height of the front of the car is an A/C condenser stacked in front of the normal engine radiator;

-The passenger side lower "mini" radiator is for Engine oil cooling; and

-The drivers side lower "mini" radiator is an auxiliary Radiator for engine coolant.

A rational reply; I was looking at LCI parts. Note that the B58 engine has a heat-exchanger for the oil cooler rather than the older oil cooler.

Thanks for the detailed info. That's what I was interested in. So, do all of BMW's IL6 engines have this much cooling? If not, why do some and others don't?

[zibbit]

No, I don't believe they all have as much cooling.. From what I understand only M Sport Editions have extra coolers to accommodate for track usage..

You meant the genius was right?

Only accidentally, as he appeared to make no effort to follow either link I provided, nor provide any counter argument regarding LCI vs. pre-LCI equipment. Argument from ignorance is a logical fallacy; any conclusion reached by logical fallacy is invalid.

My exasperation at people using logical fallacies has been sorely tested over the last 18 months or so.

The original post asked what the rads were for. The links you provided did not explain this. "coolant" is NOT an answer either, so if you can't read the post yourself, you shouldn't be criticizing others. If you know the answers, you can provide a correction without being so ignorant. Isn't there enough ignorance in this world lately?

An old post from ttrueraider says this about the pre-LCI coolant radiator/oil heat exchanger combo. Post#1 does seem to be LCI Xenon, and it seems to be coolant radiators on both sides(right?), so it probably is a pre-LCI 328i M sport.

"They all have a transmission fluid heat exchanger. 328i Sport lines have one auxiliary engine coolant radiator in the passenger side front wheel well and M Sport lines have a second auxiliary engine coolant radiator in the driver side front wheel well. All 335i's have an engine oil cooler in the passenger side front wheel well. The 335i M Sport also has an engine oil heat exchanger in addition to the oil cooler in the wheel well and it has an auxiliary engine coolant radiator in the driver side front wheel well. "

I should have used a picture of mine, but I couldn't get a clear pic that showed all the rads as clearly as the picture I posted did. I didn't realize there would be a difference as it appears to have the same rads as my '16 435 M-Sport.

I thought it was only the Track Handling Package... or does that just delete the fogs to allow more airflow to the radiators that are already there?

Check this out: http://www.realoem.com/bmw/enUS/part...BMW-435i&mg=17

The trans oil heat exchange looks distinct. The aux radiator and oil cooler look similar(their brackets look alike too), but tracking the coolant hose versus oil line will distinguish the two.

[floydarogers]

Yeah, I woke up this morning thinking: what a stupid reply.

Especially since I, too was "ignorant" in not recognizing that an LCI car might be different than a pre-LCI.

Guess what: I apologize for being a bit of a jerk in this thread.
