Weird noise coming from engine and transmission

Post  dreamur on Sat Mar 24, 2012 9:11 am

Hi guys i have a 2 year old GL elegance and For the past few months I have noticed this strange noises coming from -

engine bay: high pitch whinning sound especially after couple of hours driving and the engine is quite hot you can hear it inside the car while driving. I thought it was the aircon but it was still there even after I switched off the aircon it is not consistent though and happened at random intervals i had it checked at mantrade and the technical advisor said it could be the water pump.

Transmission: when I shifted the gear to D there is this grinding sound that I can hear if I roll down my window or open the door I noticed this when I ordered drive-throughs where I need to roll down my window or open the driver side door. Mantrade TA said it is normal when shifting gears from N to D.

Do you agree with the TA or noticed these things. Appreciate your advice.

It could be the idler bearing causing the noise. I suggest before having your unit serviced, ask for a 2nd opinion in other Nissan service centers such as Shaw or QA who have good technicians. If you happen to go to Shaw, look for Benjo who services my unit.
