Two weeks ago I was saying how good these pumps are, now I have two blades and 1/2 of two more broken off and in the motor or hoses, I can force water backwords from a T back through the oil cooler to the pump, from the T is goes through the headers, I can take the water manifold off leading to the headers and check them, I can also check the hoses back to the header from the motor. If they are in the motor, what do you do?
