How many amps does a cooling fan draw?

What is the difference between a pusher and puller fan?

Why are there two fans on a car?
The cooling fan in the engine compartment should turn on to pull air through the radiator and A/C condenser. On many vehicles, there may be two fans: a main cooling fan for the radiator, and a second fan for the condenser. Both fans should come on when the A/C is on. The engine may also run hot and overheat, too.
Are pusher fans better than Puller fans?
Electrical fans can either push air through the radiator or pull air through it. A pusher fan sits in front of the radiator. It pulls air through the radiator and has less impact on airflow at high speeds than a pusher fan since it is behind the radiator. Puller fans provide more cooling capacity than pusher fans.
How much horsepower does a fan Rob?

Why is my Jeep running hot while sitting still?
If your Jeep is running hot while sitting still your fan must be near non-functional. I will see if I can locate the operation explanation for the fan… Sounds like maybe a plugged rad or thermostat. These jeeps tend to run a bit hotter to begin with so I put a 180 degree t-stat in mine when I was chasing my cooling issues recently.
What happens when the thermostat is stuck open on a Jeep Cherokee?
When the thermostat is stuck open, the vehicle will be getting too much coolant. On the other hand, if it is stuck in the closed position, the radiator will not be getting any coolant at all.
