I have margalla,when i turned on the ac it decreases water after 1 day,with out ac it is ok,the gaskit is ok,please help,
Start by checking the radiator cap for proper sealing under pressure.
most probably is gasket issue..... make sure about that
its no problem as long as car is not over heating. Most probably there is a small leak or may be steam is leaking. dont worry keep a check on water simple.
I got radiator serviced once,after few days i faced the problem of water boiling in resv bottle.I kept observing the radiator for many days,one day i found little moisture over the joint of upper raditor tank & fins.Although im running the car still with that moisture always over the joint which means that coolent leaks a little every time i drive.Whenever i pour water in resv bottle ,this car always make it overflow to ground after a short travel.Cant understand why.Though i know its leaking a little quantity of coolent but why not it accept more water.You should also check minor leaks in cooling system.
May be the radiator cap problem try to get new one .
thnx prb solved by changing the radiator cap,from last 5 days no change in the water level.
Thank you for the update. I am glad that it was just a minor issue.
