Peace be upon you. I have a used, original water pump, but it has a slight noise before removal. I don't know if it's from it or not. I also have the small oil lifters for the 6.2 engine for Escalade and Denali from 2007 and above, American, under original. I bought them new, installed them, removed them, and installed the original when it became available. Selling to the highest bidder. Contact is available at all times. Location: Taif.
