The Under the Hood Channel explores the systems that make your car function correctly. Learn about car parts and systems and how to do routine maintenance.
The mechanics from Fast and Loud work furiously to restore and old Ford Model A truck in time for a swap meet.
Watch as the gang from Fast and Loud put new hydraulic brakes in a classic Ford truck.
Most modern cars use a water-cooled engine with a radiator, hoses and a water pump to circulate coolant throughout the engine. Air-cooled engines want none of this.
Timing lights come in a few different shapes and sizes, and range in features from bare-bones functionality to lots of bells and whistles. Do you know how a timing light works?
Just seeing the phrase "positive crankcase ventilation" probably makes your head hurt, because it sounds, well, complicated. But it really isn't all that complex.
Whether you're stuck behind a slow-moving pig truck or just trying to jump off the line at a red light, quick engine response is important. Here are 5 ways to get more out of your engine.
Your car's engine control module (ECM) continually monitors a vast network of sensors to ensure operating conditions are within normal range. Do you know what the ECM actually controls?
Unlike the ever-present ads for drugs on television, there are many pleasant side effects of keeping your car's engine lubricated with oil. Find out what it takes to keep things moving.
A tremendous amount of force is applied to your car's crankshaft while you're driving. The result is lots of crankshaft vibration. How does a harmonic balancer solve the problem?
Two relatively cheap filters can keep your engine healthy and smooth-running for a long time. The only catch is that they get so dirty you occasionally have to replace them.
Your engine needs just three things to run: air, fuel and spark. That said, it's easy to see why the intake manifold -- the component your engine breathes through -- is so important.
A cold air intake is a fairly inexpensive modification and a lot easier to install than most other engine mods. But what does a cold air intake actually do?
The traditional water pump is a relatively simple, belt-driven component. But could an electric water pump be more efficient and more in tune with your engine's specific cooling needs?
Does static timing your engine sound a little too intimidating? Well, if you can pop the hood and easily identify your engine's distributor and timing belt, you're probably up to the challenge.
It may take a bit of time to understand how this ball gets rolling; but once you get it, you'll see how it just might take hybrid auto engineering to the next level.
The sleeve-valve engine may have already been dismissed as a historical relic; however, at least one company is seeking to bring the sleeve-valve engine back into action -- with a few modern twists.
Internal combustion engines aren't going away anytime soon. And since a practical alternative can't be ready for use within the next few years, we need a better internal combustion engine in the meantime.
The wave disk generator is a propulsion system that could revolutionize the way we move our vehicles. But we've all heard that before, right? So what makes this one so special?
Your car's engine always leaves behind some portion of unburned fuel. Good thing the secondary air injection system is there to help clean up the leftovers. But is it really necessary?
Four strokes, less fuel. How's that sound? With the addition of just a couple of linkages, an Atkinson cycle engine can complete all four strokes with a single rotation of the crankshaft.
The Grail Engine takes a variety of modern, cutting-edge engine technologies and puts them all together in one package. Honda and Ford have already shown interest -- should the rest of us?
Ever since inventors have tried to get cars moving, they've tinkered with the possibility of alternative fuel systems. What does an HHO system have to do with water, and does it actually work?
Whether it makes your car sound like a swarm of angry bees or the deep rumble of an earthquake, your car's exhaust system is doing its job every time you turn the key.
If you're buying a new car, you know air conditioning is almost certainly a standard feature. But it wasn't long ago when AC was an expensive option. Find out how this now nearly universal feature works.
As if the price of gasoline isn't bad enough: Did you know that the fuel in your car's gas tank is slowly evaporating away? Even when parked?
