Allure 470 Chassis A/C compressor

Good info for 2005+ Allure 470's follows. The clutch on my OEM Omega 20-46333-HP compressor failed. An identical new compressor costs $162.82 from Virtual-AC ("www.virtual-ac.com/AC-part/20-46222-HP.html"). The Omega clutch p/n is 22-20201, the omega manifold p/n is 21-10211-AM.

Does anyone know the exact freon capacity of the system? This is critical info but it's absent from my coach.

I wouldn't want to hazard a guess as to the critical charge of refrigerant that's in your system. But I am sure someone here or the manufacturer will be able to provide that information.

Keep in mind that Freon is just a generic name used on some refrigerants by some manufacturers such as R-12, R-13B, R-22, R-502 & 503

You most likely have the refrigerant R-134a in your system

A few ounces one way or the other shouldn't be that critical, but I would definitely be more concerned about the running pressures of your system measured by manifold gauges. These will correspond with the type of refrigerant, relative humidity & ambient temperature.

Also things to check are Oil in the system (correct amount, and type) as this can cause premature failure on components as well.

Hope this little bit of info helps...

Also be aware and IMO stay away from the refrigerant snake oils sold in little can at some Auto Parts Stores. While some may claim to work, and might for a little while, they may also damage your system.
