I’m replacing the water pump in my ‘74 Scout II (345 V8). I got the water pump free of the housing and put a finger inside the discharge pipe to the radiator (the large, lower one). I fished out three light gauge wire springs (possibly used to be a single spring that has fallen apart) that are badly rusted and brittle. Any ideas what these are? What would this be from or for? Is it possible it travelled through the coolant system and got lodged here?
