2002 Jeep Liberty leaking water pump

I have a 2002 Jeep Liberty I have noticed that over the year I have had my truck the motor area seems to be getting rusty colored I took it in and they said that my water pump has a leak and said that it has been leaking for a long time how could I have over looked this I take it to get a full check up and oil change and was never told that I had a leak so what do you think I should do?”

Just replace the water pump. Many water pumps leak a little through their weep hole so that the water seal remains pliable. Mercedes Benze even states that some loss through the water pump weep hole is normal and not to replace the pump until the loss becomes large. As long as your temperature gauge ran normal, it has done no damage to the vehicle. The same truth holds for oil leaks, as most engines leak some oil as they age. Unless the leak makes a mess and starts smoking as it hits exhaust parts, it’s no big deal as long as you check to make sure the oil level stays correct inbetween oil changes.
