I have recently noticed that when I turn on my A/C I hear a high pitched squeal coming from the front passenger side engine bay. The squeal only happens when the A/C is on and will stop when I turn it off. Is the belt the problem or is it something more? I have looked under the hood and it looks like that belt would be fairly simple to replace. Does any one know how to get the belt off?

| On the surface, it sounds like a belt to me. |

Belt to AC clutch.
Usually the belt. |

What you're hearing is the belt momentarily slipping on the pulleys until the compressor comes up to speed. Torque demands are highest when you engage the compressor from a stop and if the belt is loose/worn, it squeals until the compressor is brought up to speed.

| I've been having the same issue. I took my Pilot to my local dealer and was told that it was the AC Belt Tensioner, not the belt itself. Although I do believe that the belt will have/need to be replaced at the same time. I'll keep you guys posted if I get the service done any time soon. |

| I have the same problem with my 2003 Honda Pilot - squealing noise when A/C turns on. Does anybody know if there is a TSB available for this problem? |

Issue is most likely either A/C compressor problems, a worn belt or a defective tensioner. Diagnosis consists of looking at the belt (cheapest), testing the belt tension, and then checking the A/C compressor pressures.
No TSB - on an 7 year-old vehicle, a worn part is quite likely. |

Replace the belt before you do anything else and see if it goes away... replacement is easy with a long closed end #14 wrench... put the wrench on the tensioner bolt and push it counter clockwise, it will be a little tough, but it will take the pressure off of the belt so you can slip it off...
i recommend replacing with a Goodyear Gaterback belt over OEM Dayco... Much better belt and will last much longer...
I got mine at AutoZone for $18 |

| It's most likely the tensioner. Mine was squealing w/the AC on and my independent shop replaced it while replacing my timing belt, water pump & belts. They said it was completely shot and charged $100. additional to put in a new one. |

What was the total charge for service? I'm thinking of biting the bullet and having mine done as well. |

| I agree - start with the belt. I'm saying that my mechanic had everything apart for a timing belt, was replacing all external belts anyway, and found the tensioner to be worn out completely. The Honda dealer also said it was the tensioner a while back. Total cost, to answer the other question: $742. for the timing belt, water pump, belts and the new tensioner. Not a fun way to spend that kind of money but a much better price than my dealer quoted. |
