Hi all,

Some tips please. The AC compressor on my 2008 Entourage is making a knocking sound and the local dealership advised it should be changed, which makes sense. I am unfamiliar with auto repairs in the US as I come from the UK so, questions are:

  1. Will I be better at the main dealer using OEM parts or could a normal, possibly cheaper mechanic do the same job?
  2. Are there any linked parts that should be replaced at the same time as the compressor to possibly save money later?
Grateful for any help and advice

By the way, still loving the space and ride quality of the car.

:confused:

How many miles on car?

Climate in your region? EDIT: Bradenton Florida =Hot, lots of A/C use =
(Please remember to add info in your "sig", aka "Signature" in your opening post so search engines can see this info....
Most "Search Engines" don't see the info in your "sig".
(Helps those posting on small screens while composing responses.)

EG: How much is system used.... Run all the time or seldom used? EDIT: Bradenton Florida =Hot, lots of A/C use =


To begin with there is a TSB on the A/C compressor clutch hub... Symptoms are knocking sound while compressor is engaged (running)

Part itself is pretty cheap IIRC, about $8 and it's less than a hr labor.
IIRC Pull left engine shield off, remove A/C drive belt, remove center bolt... then remove hub. Install new hub, tight center bolt, reinstall belt and engine shield.

*********************
1: Create a account at Hyundai and Kia Tech website.
You can access service manual, and see TSB's (Technical Service Bulletins)

Download the TSB's for both the Sedona and the Entourage. Remember that Kia mfg'd the Entourage and Kia sold alot more Sedona's than Hyundai did.

2: Kia made the Entourage - Keep that in mind.
3: Kia parts are cheaper, as a example and this is from memory, the A/C Field Coil (The part which causes the compressor clutch to engage compressor)

A/C Field Coil
Hyundai= $78
Kia= $43

For the SAME part.

4: If Entourage is out of warranty, I'd have Kia do the repairs. Kia techs see more Sedonas than Hyundai techs do.


4a "Parts" as mention previously KIA mfg the Enotourage and Kia parts pricing is considerbly lower.

A: Parts prices from "Out of State" dealers (online dealers) is usually lower than your local dealer.
B: IN most cases your local dealer will price match. (If they have any sense)
It adds to their sales volume
They can add it to their regular stock order- and this saves you shipping... Trade off is paying sales tax vs ordering online.
C: Hyundai Dealer can "order" from Kia /and or Kia parts.... That is the impression I got, but on the servicing aspect Kia dealers can't tie into Hyundai servicing software.

Ordering parts from "Out of State" dealers
5: If the compressor is knocking /has sustained damage you will need to do some research.

(An A/C shop that specializes in A/C repair might be a better option.I found Hyundai Service severely lacking)

Best scenario=
TSB on Compressor Clutch hub fixes "knocking sound" and repair is done under warranty.
(This is a COMMON ISSUE)

From there:
Replace compressor
Replace field coil ($43)
Flush lines, and/or flush evaporator /condenser core , expansion valve
(Entourage has rear A/C as well... so ditto)
Replace dryer
Evacuate and recharge.

Worse case:
Some cars you can't flush some compents, you have to replace them if they have "Black Death Syndrome" (Compressor self destructs and sends metal particles thru-out the system>

In those cases besides the above:
Replace evaporator /condenser core , expansion valve.
(Remember the Entourage has rear A/C... so ditto on servicing)


Oh, in closing:

BE SURE TO DO A DETAILED FOLLOW UP POST ON WHAT IS DONE TO FIX THE CAR.

MOST of the Entourages are "out of warranty" so no longer can people say "Take it to the dealer".


WE NEED PEOPLE POSTING DETAILED INFO ON REPAIRS!

Wow,

A reply worth the wait. Loads of useful ideas.

The car is a 2008 with !27,000 miles so no warranty.

The knocking definitely stops when the AC is turned off but as you guessed, that is not very often in Florida.

The local Hyundai dealer noted the knock when it was in for a "Check engine" light which turned out to be the fuel cap.

Their only idea was to order and fit a new compressor which is why I asked about other bits. What is a TSB?

I am back in the UK at the moment but when I get back to Florida I might go to an AC specialist and get a second opinion

I will post a conclusion when I do get it solved

Thanks for the info

"TSB" is short for "Technical Service Bulletin", when you take the car to dealer they have the capability with a couple of mouse clicks to enter the VIN and see what outstanding TSB's have OR have "not" been done on the car.

@127k miles it could be the compressor, BUT the "Compressor Clutch Hub" is a KNOWN, repeat a KNOWN problem on the Entourage, aka 2nd gen KIA Sedona.

There is a TSB on a knocking noise while compressor is running (Very noticeable at idle).

Part itself IIRC is nothing more than a metal disc, with a rubber isolated center section - With the rubber isolated center section splined to slide on the compressor clutch shaft.

When the operator of the vehicle turns the temp down, or the Climatic control unit put's in a call (request) for the compressor to run (EG turn it on, Hey it's hot in here).. 12vdc is sent to the "A/C field Coil"
(Magnetic coil at the compressor)

This generates a magnetic field causing the afore mentioned hub there is a TSB on to pull tight against the outer pulley on the A/C compressor - thereby causing the "hub" and the "outer pulley" to rotate as one.

When this happens power is transmitted to the A/C compressor shaft, thereby causing the compressor to "turn"... which pumps freon to the associated A/V components- the net result of all this if the freon charge is correct "COLD-AIR".

At is relates to the TSB, the knocking noise is too much compliance /soft rubber in the hub Assembly. (Around $8 part IIRC correctly)

From what I read they changed the compound, and or redesigned the hub to make it more robust.

I know all of this because both Entourages I am responsible to keeping on "Life-Support" had this problem.

If the compressor gets bad enough to tear itself up it will contaminate the whole system. As it is I would have the compressor replaced and the system flushed and filtered. Possible the orifice tube replaced too.

Thanks again to all for the useful info.

We are back in the US in January and I think I will get an alternative quote from an AC specialist for comparison but will probably get the compressor replaced.

I will update this thread with the outcome.

The eventual solution

Hi All,
Thanks for the useful tips earlier in this post.
We got back to the USA last month and I visited both the local Hyundai and Kia dealers to ask about the pully rubber. They were both of the opinion that with the miles on the car (127k) the pully would have been replaced some time ago and it was almost certainly the compressor.
Local independent service centres could not beat the prices quoted by Hyundai and Kia (which were within a few dollars of each other) so I went to the Hyundai dealer who had previously sorted out an engine warning light.
Bottom line was $760 including tax and stuff which was actually slightly less than their original quote.
They did it in about 3 1/2 hours while I waited and it is now icy cold and silent so we can get back to enjoying the car.

Sorry about the red font. Can't get it to all change

Hi,

Just read your mail and we are going home on Wednesday. It would have been good to compare notes on how much insurance is costing you. With a UK licence I am finding it pretty expensive compared to the UK.

Just replied to your PM.

Yeah, US insurance in general is very expensive compared to the UK unfortunately.
