Funny engine noise- video included! :D
Hey guys! I recently bought my 2000 GS400. I love the car so far, but lately I have noticed an increasingly annoying noise coming from the front of my engine. I am guessing it may be my belt tensioner pulley? If you agree, please advise on how I might remove this myself to replace it. I am somewhat savvy with mechanics and think I should be able to replace it myself. I am afraid to drive the car until it's fixed because the noise is only getting worse each day. Thank you for all your help!

I'm not 100% certain its a pulley making the sound, a pulley usually makes a chirp sound. I'm thinking more possibly failing component internals. You need to pinpoint where the sound is coming from. Get a short hose and put one end to your ear and direct the other side to each pulley to see where its actually coming from. Once thats found, remove your belt and move that pulley by hand and distinguish whether the sound is coming from the actual pulley or the component. Personally, it sounds like the alternator (whether you have electrical problems or not).
