On the morning of 9/15/07 when starting the vehicle I heard a belt squeal. When investigating the belt squeal, noticed coolant leaking from engine compartment. Upon further investigation noticed the idler pulley bracket was broken causing the coolant hose to rupture from rubbing against the idler pulley adjuster. All in all, we had to replace the idler pulley, pulley bracket, and the coolant hose.

Events leading to failure: Replacement of alternator due to product recall failure: Coolant hose location: Where coolant hose touches outside edge of idler pulley adjustment nut. What was done: Vehicle will be taken to dealership for repair. Assumption of failure: Vehicle was recalled to replace alternator. When serpentine belt was tightened, coolant hose weakening occurred. Visual observation: Coolant hose is pressed against adjustment nut depressing it 1/16-3/32 of an inch. This combined with vehicle engine natural vibrations a hole in the coolant hose occurred. Result of coolant loss: Ultimately, engine failure could occur resulting in loss of vehicle control resulting in serious injury or death due to loss of coolant from failed hose. Possible solution: Nissan will repair or replace idler pulley adjustment bracket and insure proper adjustment space between the idler pulley adjustment nut and coolant hose.
