Water pump
2 Answers
Most likely, assuming both cars have the same engine. Best to compare parts numbers to ensure it's the correct water pump. For what it's worth, it's not wise to install used water pumps. The part is relatively cheap compared to the labor cost. You don't want to go to all the trouble changing the water pump only to have the replacement fail as well.
Look the part numbers up on a parts site or call a local parts store for information on what will fit. I totally agree with Ken that using a used water pump may be a dumb idea.
