Actually, I just got the Benz shop manuals on CD today from someone who copied them for me and did the same research as you guys.
I had no idea about the thermostat not being at full open till 94C!!!
Wow, that would have saved me a lot of money
.....but I suppose the up side is I have new components in my cooling system that I won't have to replace (fingers crossed) for another decade or two.
On my previous cooling problem posts no-one gave me any indication of this.....
those manuals on CD sure are handy, they've got so much more info than the Haynes, and allow you to actually conceptualize the workings of the parts rather than just how to switch them out.
well, I'll probably keep tinkering and try to get the temp. lower, but that's good to know I'm not going to ruin my engine.
Does anyone know if it matters if the thermostat arrow is pointing up? It doesn't seem like it should, since the design is symmetrical so far as I can tell.
