Hello,

Usually, white smoke coming from the exhaust means that coolant is being burnt in your vehicle's engines combustion chambers. The coolant can be getting introduced into the combustion chambers by a blown head gasket, a cracked cylinder head or engine block. On some vehicles with a coolant crossover tube the coolant can be leaking in via a failed gasket going into the cylinder head and down the valves. Here is a link below explaining it in greater details:
