2011 Honda CRV Oem Sanden a/c compressor struggles when outside temp gets to 100 degrees, should I replace it with New Denso compressor? Will it make a difference?
compressor struggles when outside temp gets to 100 degrees, should I replace it with New
Have you considered refilling your car’s AC charge?
If your AC performance is lower than it should, that’s super rarely the compressor.
And no, replacing a good compressor with a good compressor won’t do much (as long as the system is full or refrigerant before and after)
What do you mean by struggles? Most cars take sometime to cool the cabin.
Is the air coming out of the vents not cold?
The Sanden compressor was on the Honda extended warranty list due to issues with clutch. Had Freon added two different times. 98 & 07 accord, 03 Crv and 17 camry all have Denso compressors. NEVER had issues with them. Air flow from vents is weak but cold. 2011 Crv does not cool down the cabin like other vehicles
Is your Sanden compressor experiencing problems with the clutch causing it not to engage properly? Is it developing the proper pressures for your ambient temperature on the high and low side of the AC system?
Throwing parts at a problem rarely if ever results in a good outcome. Many things can cause poor cooling. While a faulty compressor is certainly possible that's usually the last thing on the list unless it is exhibiting a problem such as a bad clutch or an internal fault. More diagnosis is needed.
Sanden compressor was on Honda’s extended warranty list. Short period of time the clutch did screech when engaged. It stopped. Removed under body plastic panel for better air flow.
What is your basis for believing the perceived problem is the compressor or that the Denso model would work any better? Has the AC system been diagnosed? What are the system pressures? Are radiator and condenser fans working properly?
Fans work fine. Always have. Don’t know system pressures. Denso compressors on 1998 accord, 2003 Crv, 2007 accord, 2017 camry. All worked great. 2011 Crv is only car with Sanden compressor. Air flow is weak from vents. Leaked Freon twice. Removed in cabin for years due to weak airflow and lackluster cooling.
That doesn't mean much without further diagnosis. Checking system pressures is very basic. However it's your money, if you want to load up the parts cannon with a Denso compressor on the assumption that will fix the problem maybe you'll get lucky. I've found though that all too many people's first thought when there's an AC problem is the blame the compressor and it turns out that's not the cause. (Heck, the original Sanden compressor in my '86 Saab with 300,000 miles will practically freeze you out of the car and it has not required refrigerant to be added in nearly 20 years.)
Was the Sanden compressor on your Saab on the extended warranty list? Why does ac on 07 accord work fine but 11 Crv doesn’t? Why is the air stronger from 07 accord vents where 11 Crv is weak? The one thing different between these two systems is compressor brands. Been to dealer twice. Was hoping to get answers not in the form of questions. Can you answer my questions?
I came here to get help with my a/c problem.
The problem is that you are proposing an experiment in making a fundamental equipment change that no one here has any experience with. (If anyone here did they have had plenty of time to answer.) We don't even know that the compressor is the source of your AC problem since you haven't done much in the way of diagnosis, not even checked system pressures.
This is not a routine AC servicing question like "how do I find my leak" or "how do I recharge my refrigerant" or "why is my AC blowing warm" that has well-known and understood procedures. Perhaps Scotty would know if what you want to do is feasible but he has so far declined to chime in. (By the way, his video that you so quickly dismiss in which the lead topic is sugar in the gas tank actually contains relevant information on a possible weakness in your Sanden compressor.)
To definitively answer your question you need to either find someone who has done this conversion before or blaze a new trail yourself and let others know how you made out.
If you are still around, Scotty answered your question in one of today's videos at the 4:13 mark:

Don't be put off by the lead topic being about the Ford Maverick. The upshot according to Scotty is IF you can find a Denso model that fits and has the same electrical connections, go ahead.
@chucktobias - you have a much longer fuse than me. Hat's off to you.

Since in my case the car, and its original Sanden compressor, are 36 years old it would not be reasonable to expect any extended warranty would apply even if it develops a problem at some point.
The main question you want answered is whether should you replace your OEM Sanden compressor with a Denso compressor to improve cooling. The trouble is that there are so many variables that affect air conditioning performance that it is impossible to derive any real reliability or performance data from your small sample.
What is required to answer your question in any meaningful way is further diagnosis. For example, if you hooked up a manifold gauge set and your compressor failed to pump to specification then the answer would be to replace it. As it is though, replacing your current compressor with another brand would be an experiment. If you do that and your cooling improves it might even be due to having the correct refrigerant load after recharging the system rather than differences in the compressors. As far as airflow problems that would be an issue with your HVAC blower, its controller, your cabin air filter, and/or any obstructions in the ductwork. If the airflow is just weak in that model from the factory changing the compressor will not help the situation.
Another possibility would be to ask in a Honda-specific technical forum if anyone there has done such a compressor swap in a CR-V and what the results were.
I know that's not what you want to hear, but that's the reality. Possibly @scottykilmer or someone else here might chime in if they have a different take on the situation.
Here's a data point from Scotty's video today, he says on the original Honda CR-V AC compressors the shaft from the clutch is too thin and can snap off. Presumably before it actually snaps it's going to cause other problems with the clutch engaging properly and leaks at the shaft seal.
If that's the problem you're having and the replacement Sanden compressors of that model are not improved then replacing with a Denso compressor may make sense. I'd want to see that the swap has been done successfully before though. Modern AC systems and their computer controls are so sensitive I don't know how it would work out. (On old pre-computer cars you could swap components to your heart's content.)

This is why I dislike forums. Different people asking the same questions Over, Over, and Over.
Who diagnosed the compressor? The Honda dealership, Honda of America, and Scotty Kilmer via his YouTube video.
Was hoping to get advice from Scotty himself.
If your fuel line was leaking, would you just refill the tank to deal with the leak
Oh well. Thanks for everything.
Please be patient. We are all volunteers here. Scotty may still feature your question in one of his YouTube videos. All the best.
