Thread: Is it normal for coolant to accumulate in weephole channel?

  1. #1

    Is it normal for coolant to accumulate in weephole channel?

    I have been monitoring a coolant weephole leak since my 2016 RT starting leaking at about 600 miles. At first, drops of coolant would accumulate on the side of the motor below the weephole. I decided to not have the water pump replaced right away because many owners had coolant leaks that resolved on their own. Gradually as the miles kept adding up, the amount of leak on the side of the motor was steadily reduced. With just over 3000 miles on the bike now, it no longer leaks on the side of the motor, but there is still a small accumulation of coolant in the weephole channel that is only confirmed by putting a cotton swab a couple of inches into the channel. Is it normal to have a drop or two of coolant a couple of inches into the channel or should there be no coolant in the channel at all? Still trying to determine if the seals on the water pump have self corrected or is it almost corrected.

    If the seal was sealing totally then the passage would stay dry once swabbed out. Is some seepage normal? I am not sure.

    It sounds like it's gotten better although no coolant leaking at all would be ideal obviously. How much have you had to add to resevoir? I could see living with it if it never got any worse. Maybe it will eventually stop. I would keep an eye on everything and if you have to top off use only genuine factory antifreeze and if it's not premixed mix with distilled water. A lot of coolant these days comes premixed. I definitely believe after 30 years in the business nothing beats genuine factory antifreeze no matter the brand.

    Bought a new R1200R and had excessive spray from weephole. Replaced waterpump at 600 mile checkup. Good since then at 2200 miles-no weepage or spray whatever.

    My '16 R1200RT had several long trails of weeping over the first few hundred miles. Water pump replaced at 600 miles and has been totally dry over 3k miles. I wouldn't worry about traces on a swab stuck deep in the channel. If you see trails outside, it's not fixed IMO, although some believe coolant trails/leaking is normal.
