Small leak in water pump housing..... Please help

Discussion in 'Bling and Appearance' started by Noticibly F.A.T, Jan 21, 2008.

  1. A bike i'm thinking of buying has a small leak in the water pump housing. Its just seeping out from the bottom, and dripping slowly

    Its a Yamaha FZR 250, 89 model.

    There is also a water mark on the top of the radiator, not near any hoses or anything.

    Any idea how much this would cost to fix, assuming it just a gasket or something?

    Also, it needs new front brake pads, and possibly rear pads pretty soon. Any idea how much this would cost?

    Thanks in advance! :) Luke.
  2. The seal on the water pump has failed. It could "let go" under the 10-14 psi pressure from the hot coolant at any time without further warning.

    You have to replace the water pump itself. Sometimes clever people go to a lot of trouble to replace the seal because they can. A normal mechanic won't/can't do that.

    I can't give you a price, but I can give you the above warning! :)

    PS If it lets go while riding you could be stranded. It is a must-replace item, since when it goes the coolant could all leak out in about 10 - 20 seconds
  3. You know that about the FZR specifically? This has happened to me a couple of times (not a FZR though) and all that was needed was to replace the seal, does the FZR have a sealed unit that can't be dismantled?
  4. Got a quote to replace the whole pump. About $165 in parts.

    Doesn't matter anyway. Someone else bought the bike for more than its worth (probably didn't realise it was leaking)

    I hate the fact that people think 20yo 250cc bikes are worth a mint.... :(
