There are both kinds of filters. Consider the ubiquitous engine oil filter: the bulk of the filtration is on oil being dumped back into the pan! My understanding is that the circulating crap's only mildly abrasive, and so long as you pick it up 'soon' it's just fine to get it on the high side. One minor advantage of high-side pickup is that since the crap started with the compressor in the first place it tends to keep it out of the rest of the system, especially the expansion valve. I just didn't have much luck finding one that would fit into the 190D, so I didn't end up using one at all. -- Jim _______________________________________ http://www.okiebenz.com For new parts see official list sponsor: http://www.buymbparts.com/ For used parts email [EMAIL PROTECTED] To Unsubscribe or change delivery options go to: http://okiebenz.com/mailman/listinfo/mercedes_okiebenz.com
