Hot day- white smoke from exhaust

It was like 82 degree today and when I started my truck I saw heavy white smoke from exhaust. It’s only happened for few seconds. I usually see that kind of exhaust smoke during cold start. I am not sure if it’s normal for hot weather too? It’s only happened once.

 

Afr goes rich at start up. All tundras do that

 

I hate to say this, but in the past white smoke in the exhaust meant there was water being "burned" in the cylinder...usually a bad head gasket. Keep an eye on your coolant level.

 

Hmm I have seen this first time or may be I just noticed first time during hot weather.

 

I read alot about that I even bought leak detector kit and test fluid from autozone. But I have to remove radiator cap to test it and I was not comfortable doing that so I leave it. But I am keeping eye on coolant.
