Z3 rack cooler
 

I'm looking at installing a z3 steering rack. It's going on a M52 powered ti. I was wondering what cooling line people are using.

The ti cooler is only one bend, where it looks like a 328i cooler has more bends.

Also, the z3 rack is missing the mounts for these.

The Z3 cooler actually goes up and in front of the radiator, it's pretty substantial compared to the E36 versions and that's why there aren't any lugs on the rack for it.

I'm using an E46 ZHP rack and the 328 cooler on my car. Not sure what the E36 guys do when they swap to a Z3 rack, maybe zip tie it or hose clamp it to the rack?

Thanks. I think that is the answer. Use the 328 cooler and figure the mounts.

I just don't understand why the ti cooler isn't the same as the other e36's. Why engineer that little one for us? The bigger would have worked. Maybe the remote filter runs cooler?

Yeah, I can't think of a good reason other than the smaller cooler got them to the temps they wanted to see in testing. Possibly differences in the PS pumps between the 4 and 6 cyl cars too.

The smaller cooler is definitely cheaper to produce and they used it on all the 316 and 318 models according to realoem.

I had used a thick zip tie. I gradated to a metal hose clamp around the rack to secure the cooling loop. Works great. :cool:
