I hear roaring sound from passenger side pulley area (not from wheels since I changed my bearing recently and the humming sound of a worn out bearing will ring in my ears for sometime for me to not forget it...).

Is it sign of a worn water pump? When I acclerate under load on steep inclines the roar is quite evident but then when I come back to flat roads it is silent as a cat... (BTW, I have been slowly loosing coolant too but not dipping anywhere to determine it is a water pump).

Any suggestions will help...

about checking all your belts and their tension!

 

I am sort of having the same issue. I installed a grounding kit yesterday. When I was grounding the timing chain cover, I accidentally dropped the bolt and it went into the pulley/belt area. I searched for like an hour with a flashlight but couldn't find it, and it definitely didn't fall through to the floor. I eventually gave up and figured it would fall out. My car is running great with the grounding kit, but now I can hear some type of "roaring" sound coming from the pulley/belt area too, only when I'm hitting the gas though. Hope I didn't f*** anything up .
