NEW AC COMPRESSOR (4711371)

Very satisfied. Tricky to install on a 2006 Highlander in June 2016 due to little clearance for removing and replacing. (Hint: Rotate the compressor vertical to remove and then install the new one reversing the path. The problem with the previous factory compressor was the rpm sensor on the bottom of the compressor. For those who don't know, it compares the rotation of the compressor to the engine rpm. If there is a discrepancy, it assumes the compressor is frozen and disengages the compressor clutch so that the serpentine belt is not destroyed. The RPM sensor is not replaceable so I needed to change the whole compressor. (For those with the same problem, check the resistance through the connector to the RPM sensor. I've seen reports that it should be 65-125 ohms and another that it should be about 200 ohms. In my case, it was an electrical open, infinite resistance. (Fortunately I had two other Highlanders that I could check for reference.) Great price and after 5 months is still going strong. Dealer wanted $600 for a non-Toyota replacement. Update: Also replaced the compressor on a 2007 4-cylinder Highlander in November 2019 3 years after the replacement mentioned above on a 2006 model, this time due to a frozen compressor. The car had over 230K miles with the original compressor which is impressive. The original compressor had been making noise for a couple of years so knew replacement was inevitable. No difficulties with installing. Removal of the alternator is a necessity and taking off the manifold heat shield also helps. Total job was less than 5 hours including applying vacuum for 45 minutes and adding R134a. Very satisfied with the quality of the compressor and the one on the 2006 Highlander is still going strong 3 years later.

2005 Camry. Installed by prof mechanic as I didn't have all the tools necessary. Came with the Expansion Valve so returned that part to Amazon. Provides excellent cooling to the car. (As an aside to DYIers. old compressor clutch seized up and was the cause of the blower motor blowing fuses. Both blower motor and resister tested okay and functioned perfectly upon replacing compressor. Surprised me as I thought a non-operating, switched off compressor, would have not caused the the blower motor fuses to blow.)

Great choice, great compressor

Works great. Factory replacement for my 2002 Camry. 40 degree air. Found that the oil in the old compressor had metal shards in it. Recommend changing the condenser coil with the compressor which ive read can get clog up and cause the compressor to fail due to high pressure. My condenser was $40.00 from amazon and came with the dryer. Did not replace the expansion valve which apparently voids any warranty. Applied vacuum for 1 hour. Followed the chart for R134 for correct pressure which had equalized and was right at 100 psi with the engine off and system at 85 deg ambient temp. Also a good idea to replace any o-rings that you can get to and this is a common site of leaks. O-rings are only supposed to be compressed once. Replace the $25.00 serpentine belt while you're at it.

Denso is a good product! Works like original!
