Hi all, As I am tackling refreshing my 05 MCS slowly, I've came to dilemma. As of now, S/C is off, a/c delete pulley is ordered, bunch of gaskets, coolant hoses for upper (x2) and lower radiator section, etc etc... are sitting in a pile, waiting to be installed. Well, as I was contemplating installing a oil cooler, I took a quick glance at the rear heat exchanger area and found there are freaking webs of hoses there. So I digged around to see if anybody replaced those hoses and I was unable to find much information on those. I do understand... "If it ain't broken, don't fix'em" but while I am at it, I was hoping to get most of those things checked off. Can anybody provide tips or a reason why I should just hold off on replacing them? Thanks!
