bai -- i dont know if this is relevant to your query but here goes. i used to drive a box type corona (yep the 90s macho machine model but it was 4 door model lang) and it had a bad bad vibration problem that always happens whenever the aircon was turned on. there was no problem with the aircon though as it was still cold

it turned out that kulang sa support or dampeners ang area around the compressor. i never got to fix it though and just sold the car

basig mao ni ang problema nimo?

[finchy18]

bai IDOL tka.. salamat talaga.. parang nga kulang ng support ang compressor ko.. pero i need more comments bro.
thanx ha sa fast reply..

could be your a/c belt is just loose.

[finchy18]

yong nasa labas ng timing belt? diba dalawa yung makikita mo sa belts aside from the timing belt.. baka loose na nga kasi matagal na to eh di pa na replace....

[afrasay]

No, no the ac belt. yun nakakabit sa aircon compressor.

[finchy18]

which belt bro? where exactly? magkano ba ang belt? madali lng ba to mag pa replace?

[afrasay]

yun belt sa compressor which extends to a idler pulley then into the the engine pulley. Basta check mo kung maluwag. Bumababa ba ang RPM mo pag on ang ac?

[finchy18]

hindi nman bumaba.. normal nman.. ma ingay lng pero hinda masayado.. sometimes lng maingay kpag full a/c ako.. pag automatic a/c sya tumotunog..

[afrasay]

could be the idler pulley or the the compressor's bearing.

[finchy18]

does it costs? how much ang bearings? ilan bearings po yan? if not replace what could be the result?

sensya na sir im newbie sa aircon po..

[afrasay]

yun sa idler pulley mura lang yun aircon ala pang 200. Pero yun sa aircon compressor ang madugo. I have no idea but sigurado kalas compressor pati freon. Tapos kung throw away, eh throw away na compressor mo.

[finchy18]

sa idler pulley kpag mag pa change ako ay ma throw away ang bagong freon ko? pano malaman kpag throw away na ang pulley or bearings? anyone pls help magkano compressors bearing if ito ang problema ko.. wak sana..
