Thank you very much. You are right, it is called auxiliary water pump. It costs about $200. I just spent all my $$$ to buy this 89 300 ce. I am broke and cannot afford replacing it now. I saw the coolant leaking in between the gap of the black plastic part with screws area. Does it have a ring in between or should I tight up the screws? What is the aux. water pump for? Will I get into big problem in the future if I do not replace it.
