After having a look at many of the posts, I am growing concerned about the cooling of my 94 E500 this coming summer. Here in the SE it can get deceptively hot, and I have found that even on the level all of vehicles tend to run a bit hotter. I live atop a steep mountain (great drive every day!) but it privides sufficient stress to have put an end to my 83 300TD's hill climbing ability (no comparison here).

Question:

1. Should I consider aux cooling (I run stock at the present time)? If so, how do I prioitize (oversized radiator, transmission cooler, larger oil cooler).

Any thoughts are greatly welcome.
