1985 300SD Disconnected blue Wire near battery

Found a disconnected blue wire near my battery. Can't figure out what it goes to. The previous owners installed an aftermarket radio so I'm wondering if it is from that or if this wire was disconnected from somewhere else. I'm having difficulty tracing it to figure where it is going. Any help is much appreciated. The wire comes through the firewall into the area near the battery and is blue.

1979 300SD Turbo Diesel: after-market turbo advisable?

Ken,

Thanks for the products and advice thus-far.

My 1979 Mercedes 300SD Turbo Diesel is running great (knock on wood!), and always gets a thumbs up.

Question for you and anyone in the forum with experience with my model and after-market turbos.

Would an after-market turbo work with my vehicle?

Yes? No? Why/why not? What to look for/stay away from? Other advice?

Cheers from the Bluegrass State,

Christian

1978 300SD Oil Leaks

I've been running through a lot of oil lately so I had my engine cleaned thoroughly and ran it at idle for 30 mins. I noticed that oil was leaking from the grate at the bottom of the transmission, but nowhere else immediately noticeable. I suspect that this is the dreaded rear crank leak that requires engine removal, but would appreciate confirmation before I go out and solicit estimates. Am I correct?

overheating on my 1980 300 sd

I have replaced the thermostat,aux water pump, water pump, all hoses,had the radiator rodded out by a radiator repair shop, blower motor replaced and I am still just short of 100 degrees on the cars gauge backed up by an infrared gun. I have checked and my major problem was the radiator as the bottom was cold and the top was running hot. After all this I now have hot all over readings. The thermostat was an 80 degree one and was put in the right way. I am getting heat thru the a/c so I assume there are no bubbles in the system. The top of the radiator reads 100 degrees with thr IR gun.
