The water pump bolt can have oil on it because they go through to the engine crankcase. I have found the instructions on how to change the water pump out and here is the warning they give you when doing the job. There are three different engines that go in these, so I have found all three, they say not to over tighten the bolts and to mind the length of the bolts. Also, some of the bolts thread into plastic so be careful not to strip the bolts out. They do use to torque-to-yield or single use fasteners so you will need new bolts as well.
Caution: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Do not use paints, lubricants, or corrosion inhibitors on fasteners, or fastener joint surfaces, unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems. When using fasteners that are threaded directly into plastic, use extreme care not to strip the mating plastic part(s). Use hand tools only, and do not use any kind of impact or power tools. Fastener should be hand tightened, fully seated, and not stripped.
Caution: This vehicle is equipped with torque-to-yield or single use fasteners. Install a New torque-to-yield or single use fastener when installing this component. Failure to replace the torque-to-yield or single use fastener could cause damage to the vehicle or component.
