I'm new to this 2016 LR4. Not long ago I detected a coolant leak. After a few days I detected the leak was coning from the water pump. No problem Ill replace the pump. The new part came in with the new bypass pipe to insert in the rear. I put everything together, filled with water for leak test, and still discovered a small trickle of water coming from behind the pump pullly. The picture shown was taken with a mirror and shows a small steady stream of water trickling down. I watched a video of how to install the pump. I believe I did everything right. Is there something I'm missing? The video says to turn the bypass pipe a quarter turn to lock in. I could not figure how to lock it in. Did I miss something?
