How far should the fan be away from the radiator?
The last measurement you should check is the distance from the face of the fan to the radiator. There should be at least 1 inch of clearance between the two. This is to accommodate normal engine and radiator movement, and also the flex that occurs in the fan blades at higher engine rpm.
How much airflow does a radiator need?
The front opening, air intake is one key aspect to its performance. Ideally, the radiator needs to be squared up to the air. Scoops, lips, deflectors and recessed panels can be used to improve air flow when the frontal area of a vehicle is less than ideal.
Will a car overheat without a fan shroud?
Without the shroud, at idle, the fan is blowing straight onto the engine. It helps only minimally. It’s the coolant that you are trying to cool down, not the engine. So with the shroud in place, the fan is circulating air coming in through the radiator, thus cooling the fins and the coolant flowing inside.
How do I increase the cooling capacity of my radiator?
Coolant temperatures can be reduced by upgrading radiators in three ways, by increasing the frontal area of the radiators, by making the radiators thicker, or by using materials with better heat transfer properties for the cores.
Which side of the radiator do the fans go?
engine side
a “push” fan. Mounted on the engine side of the radiator, a pull fan does not interfere with airflow at highway speeds. All shrouded fans should be on the engine side of the radiator.
Does it matter which side of the radiator fans are on?
Dumb question: does it matter which side of the chassis I mount the radiator fans? You can but you won’t get the same performance. The reason why the manual says directly on the rad is because it creates the most pressure and pushes/pills the most air through as possible.
How do you tell if a fan is pushing or pulling?
easiest way if you have physical access to the fan, moisten your finger tip with water or w/e. and turn on the fans, place the finger tip (edit: in front of the fan), and you can feel the direction.
Are fans more efficient pushing or pulling?
Higher pressure air has higher density. When you push, the air in the duct will have higher pressure than if you were pulling form the other end. This means that for a given unit of time, more air flows though a pushed duct than a pulled one (again- assuming all other things equal).
