Hello Scotty, first i want to thank you for these very informative videos. I have learned a lot of new things and saved money thanks to you! But here is my question. I'm having this engine squeak problem with my 2004 1.6l Toyota Corolla (110 000 miles) and I don't know what to do with it. I bought this car in may with my wife and everything was fine at the moment (my first car actually). But in June it started to have this mild chirping which is coming from left side of the engine, from pulley and belt section (or at least i think it is coming from there). Sometimes it squeals this loud whirring/chirping type of sound when driving on a highway with cold engine. At first i suspected serpentine belt, so i changed it. No affects on that. So i took my car to auto repair shop because my skills and tools at this point are very basic. They also noticed that sound might be coming from belt section. So they checked pulleys etc. and found that the water pump was leaking and it was replaced. And just to be sure they checked timing chain. It was firm and no problem with the timing. So i got my Corolla back, took it on a drive and found that this sound is still coming. Called back to mechanic and he told me that it is probably something minor. Any ideas about what is happening or how can i try to diagnose this problem?
Okay i replaced the tensioner, but this sounds still occurs. Any suggestions how i can pinpoint source of this sound?
Okay. I will try that. Thank you :)
replace the tensioner
