Where is the water going?
2006, 75000 miles. I just super flushed and added a coolant filter w/CAT ELC. Ever since I seem to be loosing coolant, but it is not "falling" out. It has been dry and there are no signs of it dripping, and dry frumunda (if you know what I mean). I pulled the EGR valve expecting to see it wet/damp in the lower chamber of the intake manifold, but it was dry. NASTY dirty, but dry.
I wondered if the block might still be burping up some air after the extensive flush (wish-full thinking). I hate the thought of a head gasket, but I guess it is possible. Is it possible for the EGR cooler to leak rearward? The old gal runs awesome and is not puffing grey or vapor.
I am new to this site and this is likely discussed here somewhere, I just have not found it yet. If there is more on this, could someone steer me toward it.
