What does an air dam do on a truck?

Air dams are lower extensions of the front bumper that redirects air flow under the vehicle. Active air dams are automated extensions that further changes the airflow to increase aero dynamics. This system is designed to reduce drag to ultimately aid in fuel efficiency.

What does front air dam mean?

: a device attached to the underside of the front of an automobile to improve stability, aerodynamic performance, and engine cooling by redirecting the flow of air.

What does a lower air dam do?

The AirDam is fitted at the bottom of a car’s nose or front bumper. It directs the flow of air around the car instead of under it. The manufacturers term the airflow which goes underneath the car as the ‘underflow’. It is highly turbulent and also consumes more energy.

Does removing air dam affect gas mileage?

“It’s one of the things that we focused a lot on as we developed the Colorado, paying attention to how [the air] floats around the fenders, the lamps, the hood, the roof, and that air dam is a key attribute to it, so there will be a notable difference in fuel economy once you remove it.” Pressed on providing a number …

What’s the point of a front splitter?

The Aerodynamic Purpose of a Front Lip Splitter A splitter creates a boundary between the air moving at two different speeds. Air moving under a car can flow much faster if there’s a large splitter on the front because the splitter essentially “carves” the air and pushes a small amount of it under the car.

Do front air dams work?

FRONT AIR DAM An air dam can be one of those magic improvements, increasing downforce and reducing drag at the same time. It can also improve engine cooling by increasing the air flow rate through the radiator.

Do front air dams help?

A well-designed front air dam will keep the nose steady and pointed at the ground in high speed driving. This would give the driver more confidence to control the vehicle in sustained high speed driving environments.

Do front air dams increase mileage?

do front air dams help to increase gas mileage a bit? Air resistance is proportional to velocity squared. Therefore, if you drive at speeds of about over 100miles/hour, then aerodynamics takes on an effect in a cars preformance and gas mileage, but at lower speeds, the effect is neglegable.

Is the air dam on a Chevy Colorado too flimsy?

Too flimsy to do much more than impart the lower air to go around your truck. I have thousands of miles have been logged on my truck without the air dam in placed. Not once has it ever overheated. Not even in the 100+ degree weather of the south. Others can corroborate.

What does the air dam do to a car?

The dam helps create an area of air pressure in front that the majority of air slips around. You’re seeing that pressure wave when the beads of water don’t blow off the hood at 60mph. The air is going up and over the vehicle. The hood and windshield area is a negative pressure zone.

Why was the airdam removed from my GMC Canyon?

GM removed my airdam. My understanding is the airdam concept is to help create a slight vacuum at speed under the engine bay. This should help draw air through the radiator and engine bay.
