1994 chevrolet k1500 silverado suburban Questions

[Heavensdarkness13]

I have a 1994 chevy k1500 silverado suburban that I bout in 2015. Bought from a used dealership who bought it from the previous owner that rebuilt the engine. It has a nightmare of electrical problems. Well long story short "Beast" has a new starter and new radiator . He was a manual turned automatic. Well a few months ago I tried to take him out of town and didn't make it. He excessively lost coolant and it was leaking between the two front wheels. I don't want to pay a arm an a leg to get it looked at. I've been told most likely water pump or heater core but if you have any tips on what I can check before actually buying a part.if it's water pump or hoses, etc. I can do it myself so not worried about labor. ( Yes I'm a woman) I have replaced part on him myself as a hobby . Someone please help. Thanks in advance.

Likely a water pump or Hoses but needs to be tested. Could be something simple like a clamp that was not tightened at time of radiator change. If you want to DIY then a video or good pics are required.
