'99 Coolant leak. water pump or gasket?

Hey guys, I am new to powerstroke.org as well as new to the diesel world. Meaning that I just bought my first diesel an Early 99 F250. Truck has 194K miles.

I have a couple questions about some things that need fixed on the truck.

first one is that it is leaking coolant. Not a bad leak but if it sits for a day or two there will be a small puddle. I can see it is coming out of the gasket that is connected to the water pump. It drips down onto the lower radiator hose and onto the ground. My question is, does this likely mean the water pump is bad or is it simply a bad gasket? I thought if the water pump was bad it would be coming out of a weep hole? I just don't want to replace the water pump if I don't have to.

Second one is that the battery light comes on randomly. It seems to flicker on and off. The only connection that I sometimes find is that it will go off if I give er some gas and make the engine work a little. Other times it almost seems to flicker on and off when I go over bumps. The batteries and the alternator are almost brand new. All of my terminal connections are secure.

Sorry if the first one has been posted somewhere else. I have been trying to search and find answers but couldn't find any that I felt like were talking about the same leak. I attached a picture to clarify where I am talking about. Thanks for your help guys.

yup. Remove the "neck", and get a new gasket and use RTV as well. Should seal it up good.

Only thing i can think of, is check the connections at the battery and ground/s on motor.

if it is leaking at the gasket mating surfaces, the pump should be fine. the brushes in the alternator are likely worn down causing the charge light to flicker.

Thanks for the quick responses. As for the battery light, I have noticed it comes on and stays on longer when the engine hasn't been started for awhile.

I have had the same to problems with my 2000 powerstroke and the advice given is right on the money, new rubber seal at neck and brushes in alternator will do the trick for sure! Good luck with your truck.
