Hey Hotrod, welcome. Get on the passenger side and use a screwdriver to catch under the tabs on the packing nut and lever it down to tighten the nut. Also the water pump uses special grease at the rear. Not chassis lube. Others will chime in also. There is a soft packing behind that nut, don't go too tight. I've used channelocks on the nut with no dire effects also.
