Nissan Repair Questions? Ask a Mechanic for Answers ASAP
Hey there, so the idle issue has cleared up? It's just mainly the noise that's concerning you now?
We don't see alot of issues with these water pumps, but when we do they are pretty easy to diagnose because the pulley makes a roaring sound.
If you remove the drive belt and spin the pulley by hand it will make a slight roar when you turn it, then you know its bad.
a gurgling sound would generally indicate AIR in the coolinf system and require you to burp it.
it wouldn't be an issue with the pump itself or the pulley.
when air is trapped in the cooling system it has nothing to do with the coolant level.
The air has to be forced out by burping the system with a coolant bucket and holding it at 2500 rpms.
