E36 LEAKING marine engine coolant pump AGAIN (Perkins Prima M50, Volvo MD22L)

Join us this week on Sailing Nendaz as I get to work solving the problem of a leaky coolant water pump. There is a seal on the shaft bearing made of ceramic, and apparently it can be very sensitive to rust particles or limescale deposits according the manufacturer . The shaft seal has failed meaning our engine is very slowly leaking coolant into the bilge. So in this episode I aim to thoroughly flush the engine with radiator chemical flushes, and a hose pipe in the hope of properly cleaning out the coolant circuit. This video is hopefully useful for anybody with a Perkins Prima M50 or Volvo MD22L. It gives you a good guide on how to replace the coolant pump and dismantle the timing belt assembly to do so. For those that don't know the Perkins Prima M50 is exactly the same engine as the Volvo MD22L but with a different paint job.
