looks like my water pump is leaking. the coolant is running down the lower hose coming from the pump side. i changed the hose twice thinking that it was to problem, but it made it worse. is there a seal on there that needs to be replaced or would i need a new pump? is this a test i would be able to do in my driveway with basic tools, or would i need anything special? i have nearly $300 ready to buy a 3\" lift and if i can fix this without spending that, i will do anything i can.
