Replying to: rafay (Aug 18, 2006 6:52 am) I also had this hissing sound on my Pathfinder for quite sometime. I took it to the dealer and he sprayed some water on the 2 belts in the front that run around the engine. When sprayed with water the hissing sound was practically eliminated. The belts needed lubrication, so in order to fix I had to get the 2 belts replaced. Doesn't cost much but now I no longer have the sounds when driving. And yes, the sound became higher pitched when accelerated. Try to locate the belts towards the front of the engine and just spray directly on the belts while running and see if the noise is eliminated, this might save you some money before any other suggested repairs to the sound.
