Prevention of A/C compressor breakdown

[niky]

Honestly don't know. Nissan changed compressors in the Sentra sometime in the past, too.

A friend, on the other hand, had to chenage the compressor on their old Frontier.

I guess it's in the way you use them. Our Exalta never had compressor problems, whereas I had to sell my extra compressor (engine swap project) to a friend with the same car (same age...about 2-3 years).

The only thing we have had to change is the Expansion Valve, and once pa lang yun. Ang gumawa is Sterling in T. morato. Sabi nila sa ken, lagi ko daw i-gitna yung temperature setting ko sa frontier then yung fan nasa 2, and it worked for me. Di na nasira ulit yung aircon after pinalitan yung expansion valve.

Don't if this is true pero halos lahat ng nakakausap kong car A/C mechanics eto ang tip. Huwag daw laging nasa Max ang A/C temperature settings. Any technical explanation about this one?

totally agree ako sa yo sir frank, for me anything pwersado mas maikli ang
buhay. if cost of repair means nothing tuloy lang pero kung tipid mode at maalaga
IMO the best ang moderate lang ang settings. not max.

not that technical pero max settings means more work on the compressor, more stress on the parts and shorthens its life

really? hmmm... well on my starex it doesnt matter if you have it on max or not... the compressor will still cycle on and off the same way,, because of the design off the system,, because when you think your adjusting your termostat its just the valves of the heater system that opens and heats the air...so unless you turn the compressor off manually there is basicallly no difference..... by the way my starex 01 model still has stock aircon system... havent cleaned or anything done to it...and its still working fine.. and the reason its ok is probably because the starex has 3 auxiliary fans to help cool the condenser.

Actually its not only the oil that is different from an R12/R134a compressor. The major difference there are the shaft seal and gaskets. R134a molecules are smaller. If you just replace the oil of an R12 compressor with R134a oil without changing the shaft seal, eventually the refrigerant will leak out. Though it will take years I think for it to completely dry out.

As for taking care of your compressor, just make sure that you don't just refill the refrigerant. If you need to refill the refrigerant, there is leak. Make sure you resolve the source instead of just regularly refilling it. Also, have the clutch bearing replaced once you start hearing noise. If you don't, the hub might get damaged. Hirap pa naman to find a replacement hub for some compressors. Sometimes you have no choice but to change the whole thing.

If i may ask, ano yung HUB sa compressor? Is it possible that it's the reason of ethnic sound in the compressor?

Thanks

22 degrees yung temp settings ko po (Exalta STA). Okay lang po ba ito?

[niky]

Basta wag lang todo palagi, it should be fine.

18 yung lowest, di ba?

mga sir tnong lang totoo bang nagbabawas ang oil sa compressor pg nag paplagay ng freon?? my sumisingaw kse freon ko pero tumatgal nman ng months bago mahilaw ung lamig.

hindi lahat ng sasakyan na walang aux fan ang condenser ay dapat palagyan..maari nyo muna itong ipacheck lalo na ang mga clutch fan kung kailangan na palitan at dagdagan ng silicon oil..pag naglagay kasi ng fan ay hindi mo makikita ang totoong reading ng a/c system..lalo na yung mga ibang shop na binubuhusan ng tubig ang condenser pag nagdadiagnost..hindi kasi alam ang reading ng high side..sa mga nagyeyelong mga tubo lalo na sa highside ibig sabihin ay merong barado o kulang sa freon..tip lang sa honda at sa ilalim compressor alam ba ninyo na kadalasang nasisira o umiingay ang bearing ng compressor ay dahilan din sa merong leak ang power stearing?..dahil natutuluan ang compressor..sa mga model ng sasakyan na malalalim ang compressor o yung nasa pinakababa ng makina ay pagdumadan sa baha ay WAG NA PAANDARIN ANG A/C eto rin ang nagiging dahilan ng pag ka stuck-up ng pulley,idler bearing na maaring magresulta sa stuck-up o sirang compressor..sana nakatulong..at ang pinaka mahala ay ang awreness natin kung maingay ay wag na natin itong gamitin at ipacheck up na sa kilala o mapagkakatiwalaang a/c tech..mas maganda mas iiwasan ang malaking sira..
