hello, im having issues where I hope someone can help give some answers to. I recently changed my alternator as my oem was going bad, new alternator is bosch brand; however in the process of removal, coolant has spilled onto the belt and pulleys, after starting there was a loud squeak and I noticed the alternator was not charging (slipping) and once the squeaking stop then the alternator would charge again. as of right now ive changed the belt (gates) and replaced the whole belt tensioner assembly (z1) and it continues to squeak and slip. Is this happening to anyone else? is there any solution? I greatly appreciate any and all responses; thank you. (note: squeaking usually goes away after car warms up but continues to squeak after another cold startup.)

 

Tighten the belt up more

 

Yeah, tighten the belt tensioner a bit more. Also, stick with OEM belts, they're cheap. I don't trust Gates products anymore.
