Wondering if mayb even tho it's new it's no good, everything else is hooked up correctly. I've gotten new parts that were not so good before, water pump with a bad bearing n so on. If its smoking id prob see if they would swap it for another one. I see no reason if it is hooked up correctly that it would smoke. I've had 3 pumps go bad on me before and never ne smoke. I don't see nething else that could really be ur problem. Im sure it prob came with sum sort of a warranty and it hasn't been very long since u bought it.
