    So your car is drinking water ?

    Sounds like you either have a leak or the headgasket is gone on your engine.

    How can I check if the headgasket is gone or I have a leak?

    Leak should be obvious as the car will be leaving pools of water where you park it.

    For head gasket you either need have a "radiator sniff test" done or have a "leak down test" done on the engine.

    Can you smell coolent around the car or in the car.
    Normally if you have a leak when the rad level drops it will suck the coolent from your expansion tank.
    Check the expansion hose is not blocked going into the rad at the top.
    Have you used radweld by any chance.

    Yeah, I can smell coolant around the car. I haven't used radweld and also I checked the hose and it's not blocked

    Look for water marks to try and trace the leak as coolent will be very visible.
    Also don't rule out the heater matrix so check in the foot wells of the car.
    I had a leak on my car about 6 months ago and traced it to the rad at the bottom.
    A branch hit the rad when driving and made a small hole so needed replacing.
    If you can spot the leak then what speedy said will find it.

    First I had a problem with a pipe from the thermostat housing. Bought a new one and a thermostat as well. After that i had problem with the fan switch as my engine overheated and the fans didn't turn on. Changed the fan switch, filled up the coolant, for few weeks I had no problems. then the engine start to overheat again, open the bonet and the coolant tank was full and I could see how it was sprayed outside. Obviously the rad was almost empty. Changed the rad cap( a proper one) and still the same problem.

    You need to find out where is the leak is. Usually in these the bottom radiator hose clips perish resulting in coolant loss which can be fatal for the engine.
    Out of curiosity, have you driven the car much since this has happened?

    If the overflow tank (coolant tank as you call it) is filling up and overflowing, whilst the radiator is emptying out, this would indicate that you have a blown head gasket.

    Just a thought when you filled the rad back up did you bleed the system as trapped air can give the symptoms your on about.

    I'd drop the coolant and start again, this time taking the time to bleed it.

    Don't think you'll have one but pretty sure you've a drain on the block as well as the radiator. You'll have to keep topping it up whilst it's running, make sure the heater is on max and fans off. I'm positive there'll be a DIY guide for an ep2 on the internet if you have a look.

    On my car and yours will probably be the same.
    Fill with coolent to the correct mix to the top of rad.
    Turn heater in to full to open thermostat.
    Start engine and run until fan kicks in twice with rad cap off.
    As the water heats up you will need to keep topping up as air is released

    Just to add to this it will probably take around 20 min for the fan to kick in depending on ambiant temp
