My nissan sentra exhaust is discharging thick amount of white smoke special when my aircon is turned on. I've already checked my spark plug and its in good condition.

White smoke usually indicates a bad head gasket allowing coolant to get into the combustion chamber. Check to see if the coolant is low. Also, you may want to have a compression test done to see if there is a weak cylinder indicating a blown head gasket.

I see. 2 weeks ago I have my radiator cleaned and put some coolant (green liquid) on my radiator and reserve tank, do you think that causes the problem? Thank you so much.

Ps:
is there any solution I can do?

Servicing the cooling system shouldn't have hurt anything.

So most probably my combustion chamber has the problem?

Based on what you described, it sounds like coolant is getting into the combustion chamber and burning. The most common cause of this is a bad head gasket.

Is it possible that oil residue on my muffler is causing the smoke?

Not if it is coming out of the exhaust.

Good day. I have noticed one more thing. Water from my radiator and reserve tank is draining everyday.

Since that is happening, I am 99% sure it is a head gasket.
