2005 base Vibe with about 99,000 miles.
hearing alot of noise from the engine area , passenger side , up forward.
no coolant loose ,etc.
belt tensioner looks ok. a/c is functioning ok and no noise difference when i turn it on or off.
my honest shady tree mechanic is scheduled for tomorrow.
i expect it may be the water pump or a/c compressor.
will update as things progress.
Merry Christmas to all.
