My car is leaking antifreeze. What should I do?

first make sure your car is not running, you don't want to overheat and create more problems, pressure test rad, that will show you where leak is coming from (on how to pressure test, check youtube) and go from there. as far as parts, i don't think they are related to a/f leak, I haven't seen that on any vehicles that I have worked on, but could be wrong.

that side could be the water pump. check that area out. under the pulley for wet coolant.
