Sad news - I installed a new alternator but the whining noise did not get resolved. I am now thinking this is a water pump issue (fml). Hopefully I can get that changed out but this job makes me nervous due to the complexity (timing belt replacement, engine coolant flush, etc) and I don't think I have the proper tools such as a floor jack for hoisting up the engine.. this is the worst possible timing for me because the weather is starting to turn cold, so I can barely get a day where it's not raining. I'll be searching for parts that I need to do this work but I am a bit overwhelmed so if anyone has a list of parts and would be willing to post them here I would really appreciate it - the list I got before with belt numbers was so helpful and I can't thank you guys enough for providing that. Cheers!
