Aircon issue vs RPM
Aircon issue vs RPM
Guys, wanna ask...everytime I on the aircon, my rpm will be unstable between 1500 - 2000. If off aircon, norm below 1000. Yesterday, on aircon , check engine line came on, then temp shoot up to 3/4 mark. Almost 130 deg cel. Stop 1 side let it cool down for 30 mins. Then start car, off aircon, drive whole nite till this morn, no problem. Thought was head gasket coz water tank flooded....but once aircon off, no issue liao. Any advise?

so when u on, idling ke siao.
CEL come on because ur engine overheating liao.
Air con compressor not working, = air con fan not moving.
so engine will over heat.
now ur head gasket also might up lorry due to overheat.

Lift up yr bonnet, on yr aircon and see if aircon fan is running.
If not, means fan motor spoil, change it and it shd be fine.
If it runs, it may be intermittent, get it replace.
To reconfirm if headgasket has been damage due to this, open yr radiator cap and observe if there is bubble coughing out.
