Hello I have a problem with the water pump, my bike has 25,000 kms, and for some months began to lose coolant through the hole that has the pump in its lower part. I changed the water seals (mechanical seal) and the oil seal. Now after rolling 1000 km has again lost. I am thinking that to introduce the mechanical retainer I lubricated the area a little with grease so that it slipped and did not damage it. Could it be that I lose for that reason? Sorry for my horrible English
