Yes Yugo I know what is your problem, The hoses end that are going into the motor becomes dry with time and you will need to buy some fasteners and tight them together " The smallest fastener I found in LOWES was 1/4 inch and it worked OK. ", I had the same issue but my leak was coming from a very tiny hole in one of the motors too. Don't use silicone or putty, make it looks professional and even that those pumps fit lose but the leak is not from those grommets, that's is how it was designed. I hope that can help.

It's leaking out of one of your pump bodies. They sonically weld the pumps together, and they split at the seam. You will find that it will only leak when the X5 is hot. This is when the plastic expands and lets the fluid slowly drip out. The seam is about level or close to the outlet of the pump. Smear some silicone around the pump housing at the weld ("when the pump is dry" of course) let it set, and off you go.
