I have coolant dripping from what looks to be the waterpump. I dont have any loose hoses, and it seems as if the leak is where there is a gasket on the waterpump. I am new to these kind of cars. Can I just pull the front of the pump off, replace the gasket and be good to go, or do I need to replace the pump? How bad is it to get out ( I am used to V engines and this sidemount crap is really confusing me ) ,........
