Leaking coolant

Hello,

White smoke out of the exhaust happens when coolant enters mixes with oil due to a leak in the head gasket.
The first step would be to determine if indeed you have a blown head gasket.
Usually, coolant will change the color of the oil to a milky white color.

Take a look at this guide, it shows what to look for and test to determine a blown head gasket:

You have listed the engine as a 1.9L, can you confirm that it is a 1.9L and not the 1.8L.

Let me know what you find or if you have any questions.
Thank you.
