On my 2002 X type 3.0 I have a small leak at union between the metal part and rubber hose.
Just a bad manufacturing from Jaguar.
Had anybody have one of those hoses leak? They are located left side bottom of radiator
and connect from the trans.oil cooler going to the left side of engine block.
I have never seen a hose connection that slips on the tube and is held in place with 2 side clips.
There is no means of closing the rubber hose against the inner tube, like a hose clamp.
