Aircond compressor kicks in making the car extremely heavy

[Kopi]

I will advise that, your AC compressor does needs scheduled servicing. inside the compressor itself contains lubrication oil (just like cylinder oil), and should be properly serviced. same goes too with the compressor bearings (symptom of AC bearing failing : compressor emits humming sound when the pulley clutch engaged) which needs to be observed but while the compressor is taken out from the car - it's worth it to change it along (just like changing the engine's waterpump when you change the timing belt - in one go). usually it costs between 100-140 per service inclusive bearing change.

I've been using my satria since 2000, and had 6 changes of compressor - which sarcastically more often than I had to do with the throttle body, the last one was in 2006. I did the service along every 15-24mths, and it's been 8 years of good cooling and without heavy surge of RPM when the AC kicked in. AND, the old AC mech of mine always rubbed a bit of grease to the AC belt ribbed part and advised to do so from time to time so the belt belly wouldn't be too dry and too grippy at the compressor pully.... so the little slack of belt traction when the AC clutch pins the pulley, the bearing won't suffer too much sudden load and you won't feel the sudden drag too much. It does help too with eliminating that screeching sound from dry belt.
