water pump does attach to the timing cover so maybe he just meant its coming from that area? but scotty is probably right would say its either those elbows or the water pump wouldnt hurt to change both also it should have a drain plug on the bottom driver side of the radiator its kinda hard to get to unless you have 2 elbows giving you 3 equally spaced forarms and biceps or maybe double jointed shoudler youll need to jack up the vehicle to reach it. and even then it still blows out my shoulder haha but i have long arms and my jack dosent go very high so that could be the problem. but ive had both the 04 and up style radiotor and currently have the 03 and below and both had drain plugs. if you still need help finding it let me know i can take a pic next time i got my car up (probably this weekend haha)
