06 Tj 4.0
Today I checked if I had enough coolant. I had to add just a little bit but proceeded to air out the system. I went to grab the lower radiator hose and the upper part of the hose feels like there’s a hard material in the inside. Should there be hard material in the radiator hose? 1/4 of the hose I’m able to squeeze but then the upper 3/4 hard as rocks. That’s what it feels like to me if there’s rocks inside the radiator hose.
Is this normal ?
