After a 10 year slumber, I have finally completed the overhaul of the 280 engine which came in my '64 230SL. This engine performed fine on initial purchase, but due to low compression I decided to give a complete overhaul. Now the engine is back in the car and ready to attempt to start.
I suspect this engine originally came from a sedan or other source rather than a Pagoda, so the routing of the coolant lines, although unchanged from when I originally acquired, has me baffled. In particular, there is one outlet on the driver side head, as shown in the photo, a metal curved pipe with some sort of sensor on the end. Then another outlet just below on the block.
I wonder if someone more knowledgeable than me can help me get the hose routing correct? I have created a diagram, with every available hose connection labeled. If you could fill in the blanks of the list at the side of the diagram (i.e. connector "A" goes to connection "5", etc), it would be very helpful. I have included a PDF file of the same coolant diagram if more usable.
