What is VTEC and How Does it Work? - EricTheCarGuy

VTEC or Valve Timing Electronic Control is a system that's been used by Honda in passenger cars since 1991. I believe the 1991 NSX was the first production vehicle to get this system. It has since been used in several other Honda vehicles. Late model VTEC equipped vehicles use the iVTEC system which also changes cam timing as well as lift and duration. The system is designed to give you the 'best of both worlds'. You get to switch between 2 cam profiles. One for fuel economy, one for performance. A lot of people think that when VTEC kicks in you get an extra Boost of power. Not true in my experience. It does however extend the torque curve to give you more performance after it does switch over. There is no set RPM where VTEC switches. The computer looks at several variables and calculates when to activate the VTEC solenoid. It's a cool system and for the most part rarely has issues. The most common issues I've seen with VTEC are the result of low, or incorrect oil viscosity. So if you have a VTEC engine, keep the oil topped off and make sure you use the viscosity listed on the oil cap. The animations are courtesy Honda Motor Company, thanks guys.

iVTEC How it Works -EricTheCarGuy
iVTEC How it Works is a long standing requested video. Back with I did the video on the VTEC explanation I was asked about doing a video on iVTEC which is slightly different than VTEC. First you need to understand the basic operation of the cam shaft, once you have that, and you know a little about how that cam shaft effects performance, you can then begin to understand how iVTEC works. In essence, as far as the Honda system is concerned, it varies the cam 'timing' to optimize performance and fuel economy. Many companies employ similar systems to this but they may perform the operation differently. This video focuses on the Honda iVTEC system. That said, you may notice that the VTEC system on this K series is a little different in that instead of having a cam with a higher lift and duration, it switches between 1 and 2 valves on the intake side. So when VTEC engages on this engine it actually activates another valve in the cylinder instead of changing lift and duration. It still alters cam timing via the iVTEC system however. Once again, to optimize power output and fuel economy. Either way, I hope this video helps with your understanding of camshafts, cam timing, lift, duration, VTEC, and iVTEC systems. Thanks for watching.

AC Clutch Repair and Noise Diagnosis -EricTheCarGuy
This one starts out as a noise diagnosis that ends up working in an AC clutch repair on a 1998 Acura 3.2 TL. In addition to the AC compressor clutch, we also talk about repairing the AC belt idler pulley and other possible noises during AC operation. So if you ever need to replace an AC compressor clutch or have a noise coming from the idler pulley on your AC system, this video is for you. Here's some useful links.

Quick Tip-Throttle Cleaning - EricTheCarGuy
This one goes out to BowlingBallOut who posted a question about a sticky throttle on his Saturn. It was a great question so I decided to make this video in response to it. There are many different configurations of throttle assemblies but for the most part if you have a throttle that is sticking you might be able to fix it using the procedures in this video. I am aware you may not able to purchase spray throttle cleaner in some states now but I'm sure they have some alternative available at your local parts store. One very important note here is that if you have a drive by wire throttle (DBW), then I do NOT recommend this procedure. If you perform this procedure on a DBW throttle body you may need to have the throttle reset in order to get your engine to idle or even start. I only recommend this procedure if you're trying to correct a problem with a sticking throttle. If you have idle problems, I recommend you check out this article on my website. http://www.ericthecarguy.com/faq/solving-automotive-idle-problems The best place for answers to your automotive questions: http://www.ericthecarguy.com BowlingBalOutl's channel http://www.youtube.com/user/bowlingballout Facebook: https://www.facebook.com/EricTheCarGuy?fref=ts Twitter: https://twitter.com/EricTheCarGuy Google+: https://plus.google.com/100195180196698058780/posts Information on Premium Membership: https://www.ericthecarguy.com/premium-content-streaming-etcg-content Stay dirty ETCG Due to factors beyond the control of EricTheCarGuy, it cannot guarantee against unauthorized modifications of this information, or improper use of this information.  EricTheCarGuy assumes no liability for property damage or injury incurred as a result of any of the information contained in this video. EricTheCarGuy recommends safe practices when working with power tools, automotive lifts, lifting tools, jack stands, electrical equipment, blunt instruments, chemicals, lubricants, or any other tools or equipment seen or implied in this video.  Due to factors beyond the control of EricTheCarGuy, no information contained in this video shall create any express or implied warranty or guarantee of any particular result.  Any injury, damage or loss that may result from improper use of these tools, equipment, or the information contained in this video is the sole responsibility of the user and not EricTheCarGuy.
