Richard, If you will have your mechanic call me, I will walk him through what he needs to do. I do this all the time for shops that only see Deloreans occasionally. I do offer the parts as well as the tech help. If he is going to replace the water pump he may also need o rings and other gaskets. depending on how he is going to do it. The numbers are on the web site along with the diagrams and other information as well. John Hervey http://www.specialtauto.com/
