Water Pump Noise

[-=Tyson=-]

just had major service done on my R33Gtst and had the usual things replaced. I noticed on idle there is a little bit of noise coming from the new water pump ( i think), sorta hard to describe but its a little bit like the noise that pigeons make. i know that sounds weird but that the closet thing i could get to desribe it. Just wondering if they are known to be a little bit noisy?

what pump did they put in it? A genuine nissan item or aftermarket? Was the belt changed? How much tension is on the belt?

Two thing i would do, first just check that there is enough tension of the belt (obviously when the car is off), and if it feel fine, start it up and spray some wd-40 in the general area and see if it helps.

If it stops making the noise after you sprayed it i would say that you need a new belt

If not it may be the pump itself, a new pump should be quite.
