it made the noises for the first minute or so it was on and then no more. wont know for sure until i use it alot again.
one thing i forgot to say in my writeup is priming the 4 pumps.
per rudy's guidance, i pressurized the tank using a radiator pressure test setup. i have one so didnt have to go find one. you take the radiator cap off and put the tester on it and pump it up to 15psi.
then turned each of the 4 pumps on one at a time by using a jumper from ground to the terminal block labeled with what thermostat it serves. then leave them on until you can feel the pump priming or feel the coolant pulsing throught the hose above the pump. one of mine wouldnt prime so i tapped the brass check valve just above the pump with a hammer and freed it up. then it primed.
