Hello again. I decided to “blindly” plunge into the cooling system, removed the radiator cap and filled it. Afterward, I remembered the procedure of filling through the top hose, so I removed it, topped off the system, reinstalled it, tightened the clamp and fired it up. Nothing was leaking, so I let it idle for a couple minutes. I varied the RPMs as it got hotter. I turned on the heater to get more circulation through the system. When I shut it down, I noticed a small puddle of coolant under the passenger’s side of the radiator which I determined had puked out of the overflow tube. I also noticed that only the top hose and top part of the rad were warm. Could the t-stat be stuck closed? Could it be that the radiator cap is faulty as well? I also noticed what appears to be a vac line running down from the top front of the engine to behind the passenger side headlight. Kevin in Hillsboro, OR 1982 240D 191Kmi, Hildegard
