folks, I have a 2001 mustang GT with only 65k miles and barely drive her. however I noticed the other day that there was a puddle of anti freeze by the rear of the car in my garage when I pulled her out. that means that the cooling system (water pump) is in the rear end of the car. I pulled her out again today and did not see any puddles in my garage. I did not see any leaks in the engine bay nor did I see anything underneath the car that was leaking or wet. I did have to add coolant today but not much. how difficult is it to replace the water pump? thanks guys. any input is much appreciated.
