When I start my 97 Cadillac STS there is white smoke that only lasts until the car warms up but it didnt do this when i bought it three weeks ago.

I changed the oil and nothing happened but I also notice that my antifreeze is leaking. Im not sure if this has anything to do with it.

Any suggestions?

Hi:
White smoke is usually an indicator that coolant is getting into the combustion chamber and being burned with the gas. Where is the coolant leak? Could it be coming from an intake gasket or head gasket?

Since you just got the car, you may be able to go back on the dealer.

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