The 1st owner of my 2006 MDX had the timing belt changed previous to the sale. Timing belt and drive belt changed at: mileage: 105,779 date: 5/25/2012 Current mileage: 134,xxx I got the maintenance schedule from the Acura dealership and it shows the timing belt and drive belt changed but they only inspected the water pump, tensioners, idlers, bearings, pulleys. Everything that I've read and every mechanic I've spoken to says all these others things should be changed at the same time. I spoke to the mechanic who did the timing belt and he said all the other parts were inspected and looked good, no leaking etc, thus there was no reason to replace them. I understand that but I think the school of thought on this is that the amount of damage that would be caused by the pulleys/tensioners etc failing would be catastrophic. As well, the amount of labor required to replace these other parts is so high that it makes economic sense to replace all these parts while you have access. 1. should they have replaced the idler pulley/tensioner pulley/tensioner as they were replacing the timing belt? 2. I'm told by a mechanic that there will be indications if these other parts start to fail such as noise, etc. 3. My concern is I'm told that even if the timing belt is fine if these other parts fail they will cause the timing belt to fail anyway and boom half your engine is gone. 4. next weekend I'm having the breaks looked at due to squealing, can the mechanic visually inspect these tensioners/bearings and pulleys to confirm all is well or or that not enough access for visual inspection. Please speak to each of my 4 points.
