W116, Body and Interior Specific Aid

My 1990 350SDL is blowing the A/C out of the defroster on day when it's over 80-85 outside. If it's a little cooler, the A/C come out of the dash vents as it should. If the hot day cools down, the climate control will switch from defrost to dash. Is this a vacuum pod problem or a climate controle unit problem? Any guidance would be great. Thanks!

I reviewed with interest the description of the radiator neck repair kit offered on this site. Not having had any problems - never gave it another thought. After an enjoyable cruise last evening along the Niagara River, before putting the 560SL away, I was checking the oil level and was shocked to see the smallest little bead of coolant at the base of the upper radiator neck. It was only about 1/32" but when I wiped it away, it slowly reappeared. Kent, is it too late for me or will your kit save my bacon? If not, can I assume you have a better replacement rad. available?

I have a 1988 420SEL & would like to change the tranny fluid. I have been told that DEX III will work in this tranny. Can anyone verify that for me? Thanks

Hello everyone, I am working on some of the final steps of restoring my 84' 300SD and one of the last steps in the suspension. I have purchased a lot of the stuff already (from the source of course) and the rest my Benz insane brother gave me. Here is what I am doing and replacing to get back the newer ride and handling like when it was new(er). Any advice or missing items, I would sure appreciate before I get things torn down and and advice or thing to watch out for would be good also.
