Good day. I have a 2006 Honda Pilot, very satisfied. The car has 213,000 miles and still runs perfectly, however I found some problem that I don’t know how to fix. When it got to 200,000 I changed the timing belt as I should have (including bearings and tensioner) and it started making noises, on high rpm, like an old alarm with no bells, I ignored that until now. I removed the covers and found that timing belt is lose, but if I turn the shafts it tightens back as it should be. I know for sure that it is the timing belt problem because I started the car with only one belt and the sound was present. Is it the belt tensioner? The belt itself looks very good and still has clear white labels on it. The parts were not OEM and maybe the tensioner was poor quality.
