hello folks, I'm a newbe so if i start to stutter that's why. I just bought a 300 sdl in beautiful cond. It only has 136k with all maint. records.Yes the trap oxidizer has already been updated by the dealer. There are a few minor problems with it. The outside temp. display on the dash is inop. How do I trouble shoot it? Is it a lcd display? I noticed a thermostat that is lased through the front grill.I asume its for the temp display. It has a mounting tab but where is it suppose to mount? Another problem is the shock that dampens the fan belt tensioner is bad. Where can i get this part. I know, call me crazy but I bought the car even with these major problems. Thanks, any help would be greatfully appreciated

When you say the outside temp gauge is non-op, do you mean the display is blank, or has it "blacked out"? If it's the latter, a used display runs about $50, new is over $100 I think. The shock for the belt tensioner is available from Phil, click the button "PartsShop" at the top of this page.

Thank speedy, The display is blacked out. can i find this temp disp. on any other mercedes modles

I think that a temp display from all W126 models would fit: 300SEL, 420SEL, 560SEL, etc.

So what does it mean if the temp display is just blank like mine is? I assumed it meant a new sensor, but if there is any other easy/common fix I would love to hear about it. My car is also a 300SDL.
