I have a leak coming from the back driver side of the engine (that I can tell). I've read several different places it may be the EGR valve gasket gone bad. I'm not sure if this engine has one let alone that it would cause a major leak. Water pump was last replaced, so I understand that could show that the intake manifold gasket should be done too? Any help or suggestions would be great. I have nothing to lift up the truck so, I'm working with little visual space. Thank you in advance.

The best way to determine where this is coming from is to pressurize the cooling system so that you can track the dripping coolant in order to find where is coming from. Here are some guides that will help with this:

Clearly we could guess at what the issue is but there are a number of things and it is not fun to make any repairs in this area.

Let's run through this info and go from there. Thanks
