That was 3 weeks ago. The water pump pulley now has a very distinct wobble to it and the previous grinding sound seems to be coming from this area (the water pump?). I just got back from a 45 mile trip and the engine light comes on. After examining the engine, there is quite a bit of coolant splashed around under the hood, mostly under the reservoir and near the water pump. Putting the pieces together, it seems the problem is 110% the water pump or pulley bearings. What are your thoughts on what I have presented? Should I go ahead and replace the whole water pump, or bank on it being a bearing and just replace that? I am quite new to self-service, so any help is appreciated. I can provide a recording of what it looks/sounds like as well if that would help.
