Hi all, My waterpump is making a funny noice. No play at the fan and no leak yet. Since archives suggest that this may be a signal of wp going bad, I'm looking for a new one. Now this is the real problem....... I DO NOT know the manufacturing year of my engine. Its a B diesel (3000CC) from a JDM truck. (I got only the drivetrain and has no information about the year/model of the doner truck which I think is a BJ40). My question for the forum is, can I use a waterpump from ANY B engine? or if they are not interchangeable, is there any specific way to identify the year/model of my engine? Thanking all of you in advance........... Mithila | 1984 BJ43 | N: 06° 47.85' | E: 079° 53.38' p.s. Will a picture of the engine help?. In that case is there specific area of the engine which can give a clue?
