As I was pulling the cylinder head on my '91 300CE I bent a pipe that I had not noticed that was still attached. The pipe goes from the water pump, under the intake manifold, where it was bolted, to what I think is part of the cruise control. The pipe might be salavageable, but I thought that I wouldn't take the chance. I ordered the coolant pipe from the heater exchange to the coolant pump but that was the wrong one. Can anyone tell what I need?
