Engine Cooling problem
2000 Daewoo Leganza 4 cyl Front Wheel Drive Automatic 100,00 miles

It started leaking antifreeze on the back of the block under the intake. It is very difficult to see the water pump and the hoses run every where. I have no manuals as they seem impossible to find. Could this be a water pump? There is no antifreeze in the oil, and it looks like the only way to fix this problem is from underneath. Am I going in the right direction? is this simple and inexpensive?

water pump is turned by the drivebelt it has a larger circular pulley. and has coolant hoses going to it.

its on the side with the serpentine belt.

can you get a picture of where the leak is or get back there to see it?
