Coolant Leak

[aorland3]

I have a 2--8 with a 6.4L and I have a coolant leak I can't seem to find. The leak is right by the Drivers side Exaust Manifold . I replace a small pre formed hose in the area. but is it still leaking . andone ever had this happen?

Probably the Egr cooler hose or bolted flange connection. Also check the lower radiator hose, they like to leak past the o-rings.

Yup, mine is doing it too. Leaks about a cup a week. I changed the hose on the cooler and that slowed it down a little. I'm changing the gasket and the lower rad hose this weekend.
