Need some help identifying this weird noise that only comes right after I turn off the engine for a 04' MDX 120k miles.
Normally after turning off the engine, all should be quiet after a second. I have now noticed some belt slipping noise after turning off the engine. The engine does not continue to crank after ignition is off, so it is not dieseling.
I don't understand what could be continuing to rotate, after the engine is turned off.
18 months ago I had the timing belt replaced, as well as the A/C compressor. Not sure if the timing belt pulley / tensioner were replaced properly at the same time. I have recently noticed another noise coming from the drive belt, and it turns out the belt tensioner had a gritty tension. So I replaced the belt tensioner last weekend. While replacing the tensioner, I noticed one side of the drive belt seems to be slightly glazed. Upon inspection of the A/C compressor, the pulley of the A/C compressor does not entirely align with the rest of alternator, p/s pulleys. It is off by perhaps 1/4".
The new belt tensioner is bouncing a bit consistently while engine is idling. Not sure if that is normal... Any ideas appreciated.
