its a 240D.

its a new (as of this summer) temp sensor in the block. will check the grounds, thanks for that tip. would that also make the fuel gauge wacky? (i replaced the fuel tank sender w/a junkyard one and still get the same bouncing of THAT gauge when i get below 1/2 tank.....)

i know the radiator is leaking because coolant is coming from where the solid part of the top radiator connects to the fins!

man, and im trying to get out of town this weekend!
