water reduction

Hello friends, I have already posted a topic on this topic in the forum. There was wetness under the mat, it was obvious that there was antifreeze water, I took the vehicle to a master and replaced the cauliflower core and pipes completely, but the wetness still continues and the vehicle decreases the water very lightly.

Master, how many screws are there, instead of heating combs and pipe joints, first look there if it throws a single screw again.
