my coolant fan is running all the time

I have a 2009 chevy suburban. I just did a full replacement of the engine. Now my coolant fan won't stop running. I am not getting an error code. I changed sensor and theromostat. It didn't do this before. What else can be done to stop fan from running all the time. The engine is not running hot

Welcome to the forum

Have you checked the fan relay?

welcome ! if you have a clutch type fan like my 99 blazer then it will run all the time ! if you have an electric fan then maybe the fan relay is bad !
