I was wondering if I could get some feedback. I have a 2005 MDX Touring with approximately 25K miles. I began to notice a faint chirp noise most noticeable at idle. I took it to the dealer and the technician thought it was coming from inside the timing belt location. Eventually they replaced the idle tensioner and a new timing belt explaining that the tensioner had leaked some oil possibly contaminating the timing belt. When I took back the car, it was still making the same noise. I took it back and they did some further investigating using the Acura tech line source.
I have had the car with the dealer for 8 days and they have replaced again the idle tensioner, timing belt, various pullys on the timing belt circuit the water pump and most recently (at the home office request), the oil pump in attempts to eliminate the noise with no luck. They also explained to me that Acura is aware of this problem and has seen it on other MDX's and is investigating.
I was somewhat dissapointed in that the dealership was about ready to give up and return the car back to me (with this strange noise) and would keep me posted if the main office discovered anything. I convinced them that this was not acceptable and they agreed to further investigate to locate the source.
Can anyone offer some insight into what might be the source of this chirp noise. It's not a continuous sound, rather a slight hum/chirp with each revolution. I am concerned that its coming from the timing belt area in that if something eventually fails, the engine is toast.
Thanks,

I have had that noise on my '01 MDX, near the front of the engine. It turned out to be a dirty pulley. The dipstick dripped some oil on the pulley when I tried to check the oil. Over time, this causes the belts to squeak and chirp. I cleaned up the pulleys and replaced the external belts, and the noise went away.
Just run an experiment. get a can of belt dressing from the auto part store and spray it on the belt with the engine running. If the noise goes away temporarily, that's it. Beware that the noise will come back if that's the case. You just have to clean up the pulleys and replace the belts to make it go away. |

| Timing belt/water pump... Both should be replaced at same time. The pump is going bad!!! |
