What makes the radiator fan work on a Cadillac SLS with a 4.6 liter engine?


Answer by  worker5643 (40)

The SLS has an electric radiator fan, which allows it to spin at an appropriate speed even if the car is idling, which is great because that means it won't overheat if you're stuck in traffic.

The fan is powered thru the distribution block from the battery.Power is carried thur a relay and fuse to the radiator fan . All of this is turned on by sensors controled by the vehicles computer.

I assume that that engine operates similar to other fuel injected version from Chevrolet. The should be a temperature sending unit that tells the computer to activate the fan relay and make the fan turn. If the fan fails to work you typically either have a bad sensor or a bad fan relay.

The Radiator will come on when the engine has reached a certain degree. There is a temperature guage that reads the temperature when its hot it turns on

Radiator cooling fans are a type of heat exchangers. When engine burns, it produces much heat causing the vehicle parts to become hot. Radiator cooling fans are specially designed to allow the car engine to maintain a cool temperature.

Depending on the year it is either belt driven/ engine powered or powered eletrically. electric fans are usually plastic and belt-driven are normally metal

It is an electric fan and it only runs when the computer tells it that the coolant temperature is to high.


Answer by  Doug77 (1433)

The battery runs to a fuse block which goes to a coolant sensor in the cylinder head. From there is a relay and then the fan before going to ground.

It is operated by a temperature switch that measures water temperature and turns it on when the temperatures reach 190 degrees. In addition, if your climate control turns on the A/C compressor, this will also cause the fan to operate.
