I have an annoying Thumping or I don't want to call it a knocking noice.. I started my car up the other day and once it idled down I heard a strange noise coming from the front, I narrowed down to the water pump area, could the water pump cause a thumping sound if its bad? Vitals of the car seem good from watching the gauges and it doesn't seem to have an issue running of driving. The car has been sitting a lot the last year or so, I haven't had much time to drive it, maybe 200 miles in the last year.. Car is a 92, 5.0 with about 56k miles.. Any suggestions would be helpful..
