Question about 1999 Nissan Frontier
Its making a whistling noise I was told it was the fan clutch so we replaced it but it is still making that noise
Some high pitch whistles can be from the brushes of the alternator needing attention
it may be from failing idler pulley bearings
check for vacuum leaks at hose connections
