It is time to replace the timing belt on my 04 lexus ls430. I have always heard that it is best to use a Toyota water pump and i have always done that. Now the parts man tells me the timing belt kit includes a water pump made in China. Has anyone had any experience with this water pump? It would cost about another $100 to get a Toy0ta water pump. Is it worth that?. If you do that, what are you going to do with the extra water pump from china?
