Hello,
Avoid driving that vehicle until it is repaired.
When the check engine light flashes it means you have a misfire. Reading the codes will likely tell you which cylinders are misfiring, and will likely point to a bad intake manifold gasket leaking coolant into those cylinders.
You could also have a bad head gasket, but this engine will need to be compression tested (among other tests) before diagnosis can be confirmed.
If there is a creamy or milky color to the oil on the engine oil dipstick, there is likely a bad head gasket or intake manifold gasket.

Thank you for answering my question... Replying : There's no milky look or anything from the oil, but only now the antifreeze from the coolant drains within 15 min of driving it . still overheats tho can I put BARS LEAK BLOCK SEAL HEAD GASKET FIX see if that works to stop the leak ?

I never recommend putting stop leak or any quick fix product in an vehicle.
Are you seeing white smoke from the tailpipe? Can you see the leak, or is it completely internal?

I think its internal, i dont see the leak and yes white smoke comes out of tailpipe when i start it up in the mornings.

Ok, sorry to deliver the bad news, but it is about 90% likely you have a bad intake manifold gasket or bad head gasket. Intake manifold gasket is what you should hope for, and those off the shelf miracle fixes tend not to work, and can cause blockage and damage inside the engine cooling system.
If it is the intake manifold gasket, it will be pretty obvious when removed, but compression testing the engine will show if the head gasket is blown.
