Aircon / Engine malfunctioning

**CarPainter** · December 20th, 2012 05:34 PM

Sir, what could be the problem pag namamatay ang engine when the aircon is on? The scenario is this, sa unang bukas ng a/c ay oks naman ang idle, actually tumataas pa nga po ng konti ang rpm which is good. But after around 10 minutes of driving, namamatay ang makina kahit pa naka-idle lang.

Hopefully, hinde po ganun kagrabe ang sira at masolve po asap ang problem...mahirap din po magdrive pag mainit ang panahon.

By the way, ride is honda. Your immediate response will be very much appreciated. TY

not sure sir.. check nyo po yung bearing ng compressor nyo... baka po dyan ang cause ng problema... naninikit na ang bearing...

parang masyadong mababa ang idle mo. try mo increase by 100rpm, test. increase by another hundred, test again. idle speed should not be below 500rpm. most engines will increase the idle when the ac is started.

bro glenn's advice is worth checking. ipa check mo ang bearings using an ultrasonic detector.

Sir, maayos naman po ang rpm ng auto, tumataas pa nga po menor pag inopen na ang a/c. The problem occurs pag medyo matagal ng nakaopen ang aircon, namamatay na po ang engine. Sabi ng isang mekaniko na tumingin ay nasobrahan daw po ng karga ng freon...kasi daw umiinit agad yung parang mga tubong dinadaluyan ng freon kaya hinde kinakaya ng engine...possible po ba ito?
Ang solution nya ay babawasan daw nya ng freon para hinde na mamatay ang makina kahit pa matagal na naka-aircon...tama po ba tong gagawin nyang ito?

Kung nangyari ito after mag pakarga ng freon ay possible high pressure nga mag cause ng problem. EFI or Carb type engine mo?

Not sure sir, kakukuha ko lang po kasi ng auto...pero sabi ng previous owner ay pinakargahan nya ng freon at pinacleaning na rin. Carb type po, honda hatch. TY

Pa check mo na lang sa aircon specialist. Medyo malayong carb adjustment kasi kapag umiinit lang saka magluko.

Sir, just an update. Already brought my ride to a car specialist then had my ac checked. Ang diagnose nila kaya daw namamatay ang engine pag matagal nang nakabukas ang aircon ay dahil daw sa busted compressor kaya umiinit ng sobra ang mga hoses at hinde na daw kinakaya ng engine...tama po ba to?

Kasi nung pina-on ang ac ay maingay na daw ang bearing. So his immediate recommendation is to replace my compressor kaso may kamahalan kaya hinde ko muna pinagalaw...and I want to seek some advices here first bago ko po papalitan baka kasi may mas cheaper & reasonable solution but for long term din naman.

Ang tanong ko lang po, pag maingay ba ang bearing ay dapat palitan na agad ang compressor, hinde po ba pwede irepair lang or palit lang ng bearing kung sakali? TY

baka repairable pa yung compressor...

Depends on which bearing pinaguusapan. If yung clutch bearing lang pwede palitan. Pero kung internal bearing na ang stuck up either overhaul compressor (not recommended per my experience) or palit na talaga.

Worst case aapoy ang engine compartment mo when the friction heat ignites something flammable
