Although I am an experienced mechanic, a problem arose when changing a water pump from a 2004 Eco Sport, brings a 2.0 engine with double camshaft equal to the focus and other Ford, the case is that it only has 3 screws and usually it is very easy, the case is that it did not come out so easy and caused me many headaches, after trying to take it out with a chisel I only managed to break a leg, good I final And so I had a better access, my recommendation for these super stuck pumps (which is rare), is to take a barret and a large hammer and hit it hard at the top next to the rotor, once it separated, I introduced a screaming in the upper part and hit the bottom, I did it again at the top to introduce more the scarter and the next time I hit the top already came out.
