Description of operation of Genesis 2014 Sedan 3.8 Liter cooling system

[OlderGuy1stGenesis]

In exploring my 2014 Genesis 4 door 3.8 liter during my last oil change, I noticed that it uses a sharp, multi-metal scalloped blade driven by a traditional DC electric motor.

I am looking for an accurate description of operation of one, the car without the air conditioning running, and two, with the air conditioning running in the summer and spring and fall months. Usually there is a fan temperature switch on the bottom of a radiator, one or two electro-mechanical relays, a fuse somewhere, etc, etc, etc.

For example, a 2000 Camry will have a temp sensor on the bottom of the radiator and individual separate relays that bring on fan #1, and fan #2. With the car running, if you carefully disconnect the connector from the radiator temperature sensor, BOTH Camry fans will come on, a nifty quick test for operation of your Camry fans !

The Hyundai Genesis is a different car. Different companies do things differently.

I am interested in electrical paths, temperature sensors, relay(s) sequence of operation starting with ignition switch on, etc.

So why am I asking this ? answer: Having this information will help me and others, not only to troubleshoot the system but understand when something may not be working correctly.

As an example, it is possible on a Toyota Camry to lose operation of the second electric fan for air conditioning but not immediately realize it. (There are different variables: number of fans ? , how the engineer controls air conditioning, newer control by the car computer or ICU which takes other issues into consideration, meaning fans may be on or off for other reasons) Thank You.

Are you asking about the radiator fan? This is all kinda deep. Maybe there's a Hyundai mechanic on here that can answer some of your questions.

Yeah, that's the idea. They have made this stuff far more complicated (than they needed to) I worked in commercial HVAC and in getting introduced to modern computer controlled refrigeration machines, the first thing you start with is the order and design of startup and shutdown, This switch closes mechanically or electrically or electronically, then ''B'' occurs, then ''C'' can occur. It gets confusing fast.
