I have an Oday with a Universal Diesel motor and recent purchase. attempted to start the motor and when i did the impeller in the pump was sucking the water out of the bucket but when i looked closer one end of the water/antifreeze manifold/heat exchanger had blown off the left side end looking in from the engine access panel looking aft! Can this be fixed or soldered or do i need to buy one? where would i find one such part?
