I think I found what the problem is: the alternator bracket was slightly misaligned by a few mm. I had a trouble to install the alternator bolt A. The bolt A goes trough the adjusting slot and I couldn't put the bolt back in. While I was videotaping the trouble area this morning to post, I discovered the problem. I loosened the four bolts ( two to water pump and two to power steering bracket) and aligned the adjusting slot of the alternator bracket and tightened again, then it works fine now. Problem solved! I am going to mount the alternator-water pump belt tomorrow and finish the timing belt job. I will keep you updated after I finish the job. Thanks.
I just mounted the alternator-water pump belt and adjusted the tension. I reconnected the battery and turn on the ignition.
Voila! It was good, but a little rattling noise from the timing belt cover area. It's not bad, but a little dull noise, maybe timing belt is hitting the cover. It looks like a blower noise from the furnace in my basement. It's not high pitch whirling noise. I might need to adjust the timing belt tension.
I set the tensioner key hole to 11 o'clock position as I did in the past. I discovered this knowhow from a Korean Automotive College website before. The web page disappeared since then. I remember you once said that the key hole should be set at 5:30 or 6 o'clock position. I didn't know this knowhow when I changed my timing belt last time. The tension of the timing belt was so high that it made loud whirling and rattling noise. I kept driving for almost three weeks with this noise. After I adjusted the tensioner key hole to 11 o'clock position, the noise immediately disappeared. Since then I drove more than 90,000 miles. I inspected the old timing belt and it looked pretty good. I could've driven maybe 10,000 miles more, but I didn't want any risks. Since I drove for three weeks with high tension timing belt, I thought it may have shortened the life of the belt.
Any reliable information about setting the tensioner keyhole should be greatly appreciated.
