Welcome to 2CarPros.

It sounds like you may have a blown head gasket. When you get white smoke from the exhaust that isn't typical steam on a cool day, that usually indicates coolant getting into the combustion chamber.

Here is a test for checking for a bad head gasket. Take a look through it.

Here is a link that discusses white smoke from the exhaust. Take a look through it.

You are welcome. Keep in mind, the steam from the radiator (if not overheating) can be caused by compressed air entering the cooling system. When the engine is cold, remove the radiator cap and start the engine. If coolant shoots out, the head gasket is bad.

I will watch for your reply.

Take care,
Joe

Thanks again. Looked inside radiator it was full to the brim with coolant. Also car is running midway hot quickly and radiator fans aren't turning on as quickly as they should but they do work. Just takes roughly twenty minutes before they kick in.

Welcome back:

There is no specified amount of time for the fans to turn on. They are actuated when the coolant temperature sensor reaches a specific temperature.

Did you get a chance to look through the link I attached? Does the picture of the white smoke mirror what you are seeing?

Let me know,
Joe

Yes, got to look at links. Smoke wasn't as thick and seemed to be the norm. No bubbles in radiator overflow tank and car still only heats up to about midway. I took the radiator cap off and cold started the engine coolant did not fly out so I don't think it's the head gasket but you're the expert. Only saw steam coming from radiator cap once it was placed back on perhaps I did not put it back on tight enough or it needs to be replaced itself.

Welcome back:

That's good news. Honestly, the radiator caps are designed to release pressure at a certain point and allow coolant to return to the overflow. It is very possible that is wasn't installed fully or the cap itself is just bad.

Since a new cap is inexpensive, I would recommend replacing it. Chances are that is the issue.

Please feel free to let me know if you have other questions regarding this issue.

Take care,
Joe
