The fans are working. We checked all 6 cylinders by using the cylinder leak tester I have. We screwed in the hose,hooked up the regulator to air then turned the motor over til each one was at TDC. Had no air bubbles in the burp tank. Going to try tomorrow night to put plugs back in it,make sure the radiator is full and run it. This weekend when it was running I didn't really pay attention in the tank to see if there was flow in the burp tank.
