Hey guys, I took a bunch of stuff apart in my car to change out my transmission fluid (for a manual) and took the car out for a spin. When I got back and shut off the car, the radiator fan was running with the key in the "on" position but the engine shut off.

Is this normal? Did I mess something up? I went driving at night so it's not like it's really hot outside. When I popped the hood, it did seem pretty warm under there though.

 

Yes, cars do that. All of them. If it's running for like 10+ minutes after you shut off the engine, THEN you have a problem.

 

Its just venting off residual heat

 

Like others have said, that is completely normal operation.
