I am surprised a replacement compressor only lasted that long. Do you have suspension leaks? And how do you know for sure its out and no some other issue? Just seems odd. At 110k miles on my 2006, it looks original but still going strong. I am getting a rebuild kit shortly to make sure its keep going.

I took my LR3 to the dealer and they ran it on their computer. Came up as multiple suspension faults over a period of time and they said the "only" fix was a new compressor. When they quoted $2,000.00 for the job, I did a little research and discovered I could buy a new replacement compressor for between $400.00 and $700.00 (with the mean being around $550.00). I can do the work, and if I don't want to, there is a shop nearby that I trust, who will do the install for under $150.00. Geez, I knew the LR dealer was a ripoff, but $2000.00?????? I should not be surprised. I needed a $30.00 coolant sensor about six months ago, and the bill was over $500 installed.....

I have a 2006 LR3 HSE.
I had a new Arnott compressor installed by my indie shop, and I have concerns about the new position. I understand that this is a superior product, but the application of it is questionable.
It now sits obviously lower on the frame rail, where the mounting bolts sit exposed to road hazards. In addition, all the wires/hoses leading to it are exposed at the front of the mounting tray. In short, it looks it a failure waiting to happen at the worst moment!
I talked to one of the techs (not a designer/engineer ) at the company, and he stated that he was concerned about this years ago when it first came out. But, he said that they have had very few warranty claims on this! Is it possible that most Rover owners don't really care about stuff like this? Maybe their vehicles are used only for trips to the grocery stores??? He invited me to send input to him, which he'll pass on to his engineers.
Given that the Rover is supposed to be an iconic off-road vehicle, I looked at this installation and thought: "What the hell is wrong with this picture?!?! It looks like a one-off shade-tree solution!!"

Has anyone else dealt with this? Is there a better solution???
Maybe I have to look into buying sliders or fabricating a new frame-mounted enclosure?

Check prospeed. They have a compressor guard.

Also the Arnott sucks because there is no cover.

Abran,

I am disappointed with the Arnott because of the final positioning and the lack of a cover. wish I had known, but my understanding at the time was that it was a quality compressor. I checked the 'Prospeed' site that you recommended, but couldn't find anything close to compressor covers. Are there more than one 'Prospeed' companies??

It doesn’t fit.

The arnott is an AMK Compressor with a steel bracket and no cover. So yes it is quality, but they didn’t pony up for a mold to make the cover. You can buy the cover separately, Lucky8 can get them.

So if the Arnott P2807 is an AMK and not a Hitachi, does that mean the ECU has to be reprogrammed after installation? The description of this particular model by NAPA indicates it does not (of course NAPA also says it fits the OE case). Also, the stamping on the case says it is actually built by Dunlop. I always understood the Dunlop to be a Hitachi clone. Boy, am I confused...
