Alphas 2nd Gear August 31, 2015 Share August 31, 2015 My lau pok car having some weird issue again, recently I noticed the car starts to vibrates quite badly. But this only happen when the air con compressor kicks in. The vibration seems worse when the car is in the down slope position than in horizontal position. What could be the main issue here? ↡ Advertisement Link to post Share on other sites More sharing options...
GLZT 6th Gear August 31, 2015 Share August 31, 2015 (edited) Did you check for any mounting deterioration? Edited August 31, 2015 by GLZT Link to post Share on other sites More sharing options...
Alphas 2nd Gear August 31, 2015 Author Share August 31, 2015 not yet, but if it was mounting wear then the engine will have vibration too. Link to post Share on other sites More sharing options...
Canlee Clutched August 31, 2015 Share August 31, 2015 Do you hear metal scrapping sound? I had this sound and vibration when my radiator fan motor dying, causing the fan to hit against the casing when it is running. Compressor also has its own mounting if I am not wrong. Mountings have their life span and they may out-lived their time. Link to post Share on other sites More sharing options...

Canlee Clutched August 31, 2015 Share August 31, 2015 just vibration, no scrapping sound. Didnt know compressor got rubber mount, i thought it could be timing belt misaligned I don't know much about timing belt but fan/accessory belts with make screeching sound if worn or out of torque specification. If can live with it, ask mechanic to check next servicing. Good to monitor engine temperature too, incase overheating. Link to post Share on other sites More sharing options...
