"I have questions in two areas
"I have questions in two areas in dealing with the 2QM15 engine. 1) I have been advised to keep a spare water pump as it is easier to swap up the pump than to make a repair in an emergency. I am told Yanmar no longer sells a water pump for this engine. Does anyone know where I can find one? Also, my experience in servicing is that it is difficult to tighten the belt since my belt tensioner doesn't fit between the drive pulley sheave and the water pump sheave. Any suggestions on techniques would be appreciated.
2) In bleeding the system, I cannot seem to get a wrench on the inboard nut of the line coming off the high pressure pump. Anyone with a similar experience and suggested solution?"
