At idle AC on: vibration / AC off all good

Post by EFH » 15 Nov 2018 15:01

2000 4.2D Patrol

Quick question. I have noticed vibration at idle with the AC on but when you switch it off vibration is gone. I have had engine mounts replaced as they where done. Any ideas?

Vinnige vraag. Ek voel vibrasie op idle as die AC aan is maar as dit af is dood stil. Ek het reeds die engine mounts vervang. Enige voorstelle? Dis nie 'n major issue nie, net genoeg om te irriteer.

Owrd die Aircon op sy eie band aangedryf op die 4.2? Indien wel kan die band dalk kapoet wees? Of daar is 'n laer wat besig is om te gaan in die versorgerpomp wat aandui dat hy oppad uit is?

Ek het nou die radiator laat vervang en die viscous fan clutch se olie vervang, so ek glo die belt is fine, maar soos jy sê die bearing kan seker oppad wees. Sal maar dop hou

Hi all, sorry for the delayed response. Life got in the way slightly.

Thinus - Ja hy het. Idle so op +- 620 / 650. Hy dip bietjie as AC aan is nie veel nie seker to so op net bo 600.

Ek vemoed daar was iets minder cool met die diesel wat ek gekry het. Kar het vir +- maand gestaan, omdat ek nie manual mag gery het nie (hospitaal drama). Nou weer nuwe diesel gegooi - baie beter.
Die radiator het besluit hys moeg so toe is hy en die engine mounts vervang. Al die belde is gecheck terwyl die viscous fan ge-re-oil is. Ek hou oog, maar op die stadium all good.
