Yeah I know this sounds sleazy but thats what we replaced... On another trip with my brother Ronnie Cannon in his 07 47 mega everything coach.. and the genset starts shutting down.... After confirming normal possibilities we discovered the taco pump was frozen or dragging at best.... UPS overnite and a couple of hundred dollars later. problem resolved.... the 15kw is up front and radiator is on side.... pump must move the fluid.... also replaced cap and instaled a bleed valve in same side compartment. We used a fluid pump to refill and bleed air...
all is well .....we call Newell and gave advise
