I have 107,000 miles on mine and the dealership says it can hear a squeal on start up and the timing belt should be replaced ASAP @2k$ I don't hear anything different but what should I do, maybe have another dealership listen or What should I be hearing?
The '06 has two timing chains, neither would typically squeal on start up.
There are BELTS for accessories, such as alternator, etc, that CAN tend to squeal on start up, if adjusted too loose/stretched over time so they are loose, etc.
There are GUIDES for the CHAINS that can make some noise if too worn, but, its not a just on start up issue.
Chains don't squeal, but belts do essentially.
Perhaps they meant belts, such as for the alternator, etc?
You can do a simple test for the alternator's belt for example by turning on EVERY single thing that uses electricity at the same time, windows, AC, fan, lights, radio, brakes, whatever you can...and then start it, and see if the squeal is worse.
Sometimes just hitting the high beams and brakes and AC/fan on high while idling will start a short chirp/squeal, etc.
