gurgling sound when going uphill

[rajin929]

was driving through some country roads over the weekend, noticed when going uphill there's a 'gurgling' kinda sound coming from what seems to be the front right side of the car

anyone experience this or thoughts on what it could be?

car is a 07 GS sedan

Sounds like the belt or the tensioner pulley, check out this thread on the tensioner pulley:

Got the same problem on my '07 Sedan GT automatic transmission. Mostly happens on light throttle uphill or coasting at 5th gear under 2000 RPMs. At 2000 RPM or above it goes away or if I let off the gas or give more gas it goes away. Had the serpentine belt, AC belt, and tensioner pulley replaced in February, sound seems to appear more now in the colder weather.
