This is, by far, the best how-to video I’ve ever viewed. Lighting was great, volume and enunciation were excellent, explanation was clear and practical, and the video covered every part of “Where is it?”, “How to remove.”, and “How to install.” without all the other filler that most videos try to add to make themselves sound smart. Now I’m rambling. Great job with this video! I can imagine it’s helped hundreds of people!
Love it. Soo many videos I watched with useless faces all over my screen. Not explaining anything! Chris is like.... ...EGR comes off the exhaust manifold... 😂😂😂 Think I'll stick with Chris for all my car needs from now on😅😂 Soo simple and direct. Not begging for attention like all the other tubers...😂😂
I'm a 50-year mechanic, but I believe everyday is a school day, and I really appreciate the vids you make, Chris. They are so clear and helpful, and I'm sure they encourage the home mechanics to give these jobs a try and save themselves some money. You're a top bloke, as we Brits say.
You're evolving in your editing style and side notes for how to mitigate possible issues different from your own. Your're doing a great job Chris, thanks. Educational and interesting even though I don't have that exact problem yet. Keep it up buddy.
Michael Thompson Thanks a lot Michael! I try to improve my style and content in each video I do (which is very hard sometimes). I am glad you see improvement! This comment made my day! Thanks!
ChrisFix have a 99 4.3 vortec just took motor out of another bazer run great 100*** miles onit put in another 1 that was runin just bad now fuel pump workn got gas up to in line at throtl body no start pour lil fuel in starts up til runs it out everything hooked up
You, sir, are awesome for sharing all this information. I had basic education in car mechanics as an assistant car mechanic about 6 or 7 years ago, which is enough to keep my own car running. You're sharing information about stuff that might be very useful in the future and quite a lot of tips I never knew of, thanks!
Thanks Chris! My Lances was doing crazy things at idle. Ends up the EGR valve was so clogged up that the diaphragm couldn't move at all. Once cleaned, it moved great and kept a good vacuum. You are the man!
Thoroughly cleaned a bunch of years worth of gunk /carbon from my Saturn's ERG valve using carb cleaner and an old toothbrush. She's running like a champ - thanks Chris.
I'm so glad I found this. Everything I've read about how to test the egr involved a pressure pump, push and hold finger on port and see if it holds pressure is so much simpler considering I have no pump. Thanks!
As always, great instruction on removal and installation as well as how it works. The camera work is outstanding. And I really appreciate no obnoxious music.
I had no idea there was something like this in a car lol, oh well I guess you learn everyday. Thanks for the high quality stuff as usual Chris. Definitely helps me understand my car better.
Just watched your video on brake pads. Needed help on EGR advice and did a search for it. I was just thinking this video was just as detailed as the other I had just watched. Then I saw the ChrisFix thing at the end and realized it was you again. Safe to say you're my guy now.
I had my EGR coded out in my BMW 335D. The performance increase is negligible but it's one less point of failure due to carbon build up! (Also glad to see I'm not the only person that cleans their engine bay! :D)
SGM 26 I wish it was easy to tune it out because I would have done that in a second. A lot of guys who get headers will tune out their egr. Im glad Im not the only one either lol.
@@chrisfix I think I have variable valve timing but it has an EGR valve. It's a 98 acura RL. You're saying if I have VVT I shouldn't have an EGR valve?
Oh yeah, I'm going back in time. Love your channel, been a long time fan! . Just bought a ranger 3.0 for a beater with a heater. When I look up vids, yours always pops up!!!
It was this video that really got me into watching this channel. It taught me exactly how to solve my EGR issue successfully - first time! You just can't beat a ChrisFix video.
I really appreciate the video, Chris. You've helped me a lot. I have a 95 Caprice. Looks like it uses the same EGR valve as yours. Got it off today (with the help of WD-40, those nuts weren't budging). Glad I had a variety of same size wrenches as it was too tight back there for certain widths and lengths. Turns out I need a new one. Tried cleaning as per your instructions (it was gunky) but the valve just won't hold a vacuum. Waiting on a new part. The markup at local major parts shops is quite steep, $30-40 more than Rock Auto and Amazon. For those that want to check their EGR valve I suggest getting a new gasket before hand as well as a telescoping mirror. A Fel-Pro for this model is about $2. Unlike Chris' my gasket was well worn and baked on. Had to pry it off and clean the mating surfaces. The mirror really came in handy as I could not otherwise see back there without taking photos.
I hate these valves with a passion, my car was idling like i was pumping the gas, no shop knew what it was, everything from distributor til computer got replaced. No error codes. Turned out it was a stuck egr valve... replaced as a "well why not."
ChrisFix Could you do a video on how to clean the engine bay? For some reason I keep staring at the shiny clean engine of the Vet. Keep up the good work Chris!!!
I just enjoy watching ChrisFix videos, even though I take my car to the dealership for each and every service, repair and cleaning. I just dont have time to do these on my own but the pure enjoyment of watching these videos brings me back to watch more! Nicely done and very professional. Keep up the good work!
Out of all the EGR videos I watched, yours is the best. Video quality excellent, explanation and facts very nicely presented. I really enjoy watching your videos. Thanks a lot.
To stop the exhaust gas recycling valve clogging. If you have a 10 gallon tank, fill it with 9 gallons of diesel and 1 gallon of petrol. This acts in the same way as putting a can of fuel additive into the tank.
Hi chrisfix. Thanks for your great effort. I don't have car but due to my field college as mechanical engineering student I watch your videos very day and that gives me extra edge in my studies thanks very much.
Pie Eyed Performance too. The computer was trying to use the a/f ratio for the normal flow of the egr and that was not working so it had to retard timing.
Pie Eyed Maybe it's surprising but PCM's are generally designed to help an engine run better. So disable the EGR and expect slower lap times/poorer results on the Dyno.
Pie Eyed It's bad for performance for sure, just google "egr junk intake" and see for yourself. To avoid a/f ratio issues EGR should be "killed" in the ECU itself, ECU remapped and physically block the flow holes on the intake for the EGR valve. I've had it done on my car. Also when performing this it's good to take the intake off and clean the soot and carbon. Much better airflow
So If I remove the EGR Valve, and it holds a vacuum, I should just clean out the carbon and use the same valve? If it doesn't hold a vacuum, then I should get a new one? Will cleaning it help it keep a vacuum? The mechanic said I needed a new EGR valve according to the computer, so I'm gonna try to clean/fix it myself. I'd rather clean it bc a new one is about $150!
Sam Sloan The EGR should hold vacuum until you release the vacuum. EGR valves can stick open a little. Carbon can hold it open. Try a gas tank carb. cleaner to keep it clean. It also cleans the cylinders. If it leaks down replace it! Check the passage below the EGR valve if it's clogged.
Once again your video was extremely helpful, informative and detailed. I don't understand why some people feel the need to make ignorant comments on it but notice that those same people are the ones watching instead of filming their own vids... Keep up the good work!
By the way your videos are incredibly informative and easy to understand. I just recently started working at a Les Schwab and your videos have definitely made things easier to understand to perform accurate inspections for people who need to know what is going on with their vehicles.
+Miguel Leal You know how it is, the hoes need replacing every once in a while! Once they start leaking I'm on to the next, and just hope it's not contagious... Sorry, I had to xD
Dude, your videos are sooo informative and well done! I'm having some issues with my car right now and I've never known much about cars. Your changing that for me with these videos. Thanks! #NewFan #NewSubscriber #KeepItUp
+Greg Gallop The EGR system re-inserts already burned gases into the intake system. Since those gases can not be burned again, it lowers the peak combustion temperature, therefore reducing the oxides of nitrogen level.
You explain it to me like I have no idea what the hell im doing and I THANK YOU FOR THAT ! Finally get it after this vehicle, very informative keep it up man !
geesh,people giving thumbs down were just GM haters,dont need no negatively here anyways. they can go away. Truth is they learned something,just dont want to admit it.I always had to replace the vacuum line because the fitting and hose was always rotten from engine heat. seems like every older car I ever bought needed a new one too. didnt matter what brand car. they are mechanical and do wear out. you would think by now they would have invented something that didnt operate on a bellows,vacuum system. Thats so old school. I like your Vett myself. I was a Mustang guy. Problem is they suck driving in Northern MI weather. If I were to buy one now, it wouldnt see a snow flake. I love the old school cars better than the new shit they put out. At least back then there were less things to go wrong. I own a Subaru again,love those boxer engines. Reminds me of the old Volkswagens. I told the wife,if I stripped off the electronics,it would be the same engine our first Subaru had,less the electronic stuff. The basic design is still the same.
damn i love this guy videos he teaches so much and doesn't rush down anything he takes his time and explain everything i searched how an egr valve works and he explains it simple and even shows a diagram of it keep making videos bro nice job. im even buying tools now to practice what i learn on my car. thank you chrisfix.
I think this is my problem, but not sure. I tagged you in my post on FB...if you dont mind putting in your 2 cents.. 2002 SATURN SC2 UPDATE: yes it was the nasty gummed up, sticky pindle on the EGR Valve. Cleaned up nicely, running like a champ. its the original EGR, the car has over 220k on it, but it cleaned up so nicely, i put it back on. Heres to another 100k!
lmao just got a brand new shinny EGR for my motor that probably doesn't give a shit anyway... And it cost a whopping $14.00 with free shipping from rock auto.. . Have yet to install it.. Because much like my engine, I don't give a shit.
@@maruko7321 probably US dollars because from what i've seen every other country in the world has the sense to just round up to 120 in their pricing lol
From Wikki: *In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O2 in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NOx is produced in a narrow band of high cylinder temperatures and pressures.In a gasoline engine, this inert exhaust displaces the amount of combustible matter in the cylinder. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture.[1] Because NOx forms primarily when a mixture of nitrogen and oxygen is subjected to high temperature, the lower combustion chamber temperatures caused by EGR reduces the amount of NOx the combustion generates (though at some loss of engine efficiency).[2] Gasses re-introduced from EGR systems will also contain near equilibrium concentrations of NOx and CO; the small fraction initially within the combustion chamber inhibits the total net production of these and other pollutants when sampled on a time average. Most modern engines now require exhaust gas recirculation to meet emissions standards.*
Kevin Tinajero Should be soon because it needs brakes and I told him it was very dangerous to drive lol. Gotta convince him to give it back to me somehow right ;)
Really a great video, well done. I can’t believe that I used to suffer through the “other guys”videos and the endless obnoxious schtick and they don’t even have any helpful information. This is how a video should be done, to all the other guys……… 👍✌
Alpha Bravo From what I've been told the EGR is an emission thing and has absolutely nothing to do with cooling off cylinders. Hot exhaust gases are ALWAYS hotter than the air coming in the engine. Not sure why he claimed that was its purpose.
The exhaust gases displace oxygen during the combustion process. By routing them back into the cylinders, it decreases the amount of oxygen that is able to mix with fuel. Keep in mind that it is a very small amount that gets mixed in but it definitely prevents the cylinders from getting too hot and makes the exhaust cleaner. I'll also add that this system is not active during wide open throttle for maximum performance and minimum tree hugging so don't worry
It prevents overheating, after combustion process. Doesn't necessarily cool them off like he said, but does aid in the prevention of overheating, by stabilizing the air/fuel mixture.
Alpha Bravo The only thing I can think of is that by doing this and preventing some oxygen from getting in to the mix it prevents a potential lean condition which would cause the cylinders to burn hotter. But That should all be carefully regulated in a fuel injected car anyway so *shrugs*. I'm not an expert so I could be 100% wrong.
I don't how i can thnk u ...with u, i got to know...that i can also repair an old vehicle (by all videos) and save money which i hv to spent to buy new one nd i can maintain my car myself🙏😁
Kevin It is not easy to do. You need to take it off which is going to be a real pain since it is stuck on there good. You need to clean the gasket surface without getting anything in the intake, you need to put the new one on and hope it seals. Not worth all of the effort when I know the original works.
Attila theHun It cools the combustion chamber and when the combustion chamber is cooler, NOX emissions are reduced. The hotter the combustion chamber the more nitrogen oxide emissions there are.
ChrisFix but hiw do exhaust gases cool the. Combustion chamber? They are supposed to be hot, they dont cool down in an expansion chamber or anything...so they are actually warmung up the combustiin gased that enter the combustion chamber...and as the carnott law states: the less ∆temp between motir and combustion gasrd the less energy is produced( this is why cars usully kick harder in autum/winter than in hit summer)
@@ramyswar296 egr has nothing to do with that.. lower emissions ye but the price is high, bad mpg and slower car in the lower rpm. i blanked mine, got it mapped off and the car is way more responsible after that.
Viktor P Ford 6.0L Powerstrokes most definitely needs the egr delete and if you buy one ask if the egr delete has been done on it because it'll decrease performance
Don't clean it at all. Rip that junk off, throw it in the trash and replace the egr with a block off plate. The egr just hurts gas mileage and performance.
It does not hurt gas mileage or performance. It reduces the combustion temperature during part throttle operation to reduce nitrogen oxide emissions. The EGR valve is closed at full throttle.
It does reduce power at times, but sending air with very little burn-ready oxygen into the intake reduces the amount of fuel needed for a stoichiometric mix.
Nope. The EGR actually makes it run worse. It was added in effort to reduce emissions by injecting non combustible particles in the intake, using less fuel IN THEORY. However, EGRs make the engine less efficient and take away performance, while being harmful in the long run. That's why it's one of the most common modifications, especially on diesel trucks.
Another great video Chris, gonna take off and check and clean the one fitted to my jeep grand Cherokee 2.7 litre diesel here in the UK. Due another service come spring, this time including the fuel filter. Did the fuel filter near 20000 miles ago when I purchased the jeep. Thanks Chris. 😊
I've blocked my EGR off. It's complete junk. After a month of normal driving carbon buildup starts occur and you need to rev it like crazy to get it out. Only saves very small portion of fuel and causes more problems.
I'm 70 ex ENGine builder, back in 69 when I had a SUPERCUDA 440 everything was always spotless there were only 2 grades of gas reg and high test..The cause of all the buildup is EATHANOL IN THE GAS TODAY,it comes from CORN a sugar base !!
Its been a While, Nice listening to your Pointers, and perfect English.. I do have a P0404 code and I have to past inspection in a few days .. I hope I can clean it and fix it..Thanks Chris..Luis From BK NY..
I just did this on my 91 Cadi, I failed Emissions. Rated a 2.72 on NO2 test, and the limit was 2.50. Now I pass at a retest of 1.51, with the benefit of better MPG, smoother idle, and my accelerator doesn't have any lag anymore.
I'm not by any means an expert, but I'd hypothesize that it's because the exhaust is one of the hottest parts of the engine. We're you to put any sort of coating on it to prevent rust, it would likely burn off, and rustproof alloys like stainless steel might just be too expensive. To anybody who wants to tell me I'm wrong, feel free.
not necessarily rusty, more like discoloured because of the heat. if car driven regularly, it's all good because any water will quickly vaporize off anyway believe it ir not, but stainless steel also slightly corrodes, hence the goldish colour on stainless steel headers over time. also discoloration by temperature.
They are not that bad on modern gasoline engines... diesel is where you have to watch out. Diesels not only pull in more EGR gasses than gasoline, diesel exhaust gas is much dirtier (soot).
Rusu Traian Cristian Egr cools the engine by stopping combustion from happening so if there’s 80% clean air and 20% Egr the engine isn’t able to combust the 20% so that means your car is slower, less responsive, and shorter engine lifespan

+Alan K well said ..
You explain it to me like I have no idea what the hell im doing and I THANK YOU FOR THAT ! Finally get it after this vehicle, very informative keep it up man !
The EGR issues I used to have in my '93 Chevy Blazer were insane!! Never had any issues to date with my '99 Ford Ranger, even at 200k miles.
Yesssss the new vid I've been waiting
Illuminati is real YES! Took forever to edit!
geesh,people giving thumbs down were just GM haters,dont need no negatively here anyways. they can go away. Truth is they learned something,just dont want to admit it.I always had to replace the vacuum line because the fitting and hose was always rotten from engine heat. seems like every older car I ever bought needed a new one too. didnt matter what brand car. they are mechanical and do wear out. you would think by now they would have invented something that didnt operate on a bellows,vacuum system. Thats so old school. I like your Vett myself. I was a Mustang guy. Problem is they suck driving in Northern MI weather. If I were to buy one now, it wouldnt see a snow flake. I love the old school cars better than the new shit they put out. At least back then there were less things to go wrong. I own a Subaru again,love those boxer engines. Reminds me of the old Volkswagens. I told the wife,if I stripped off the electronics,it would be the same engine our first Subaru had,less the electronic stuff. The basic design is still the same.
For a '96 that corvette is cleaaaaaaan
Kaipo Fitisemanu Thanks!
I didn't know about EGR function until Chris just nailed it, thanks Chris!...👍🏼👍🏼👍🏼
damn i love this guy videos he teaches so much and doesn't rush down anything he takes his time and explain everything i searched how an egr valve works and he explains it simple and even shows a diagram of it keep making videos bro nice job. im even buying tools now to practice what i learn on my car. thank you chrisfix.
9:44 I like to use some medium strength thread locker to prevent the nuts from loosening due to vibrat......wait what? I feel so empty inside.
I think this is my problem, but not sure. I tagged you in my post on FB...if you dont mind putting in your 2 cents..
2002 SATURN SC2 UPDATE: yes it was the nasty gummed up, sticky pindle on the EGR Valve. Cleaned up nicely, running like a champ. its the original EGR, the car has over 220k on it, but it cleaned up so nicely, i put it back on. Heres to another 100k!
Every time he says it’s really simple my brain starts shaking 😂🤣🤣
🤣
holy shit, this is one of the best instructional videos I've seen yet, clear, concise, and a moron could follow it. Well done sir.
+iScott Thanks a lot! I try to make all of my videos this way!
Man the corvette looks brand new sheesh. The exterior and interior are impeccable
I was sad to see a "made in China" part installed in it
Fanks bro! I've been enlightened once more.
I truly wish W211 EGR VALVE was ad simple! Good vide.
I feel you haha e200d w211
this video saved me 119.95 Thanks
Awesome!
+Tweekedout
119 what?
lmao just got a brand new shinny EGR for my motor that probably doesn't give a shit anyway... And it cost a whopping $14.00 with free shipping from rock auto.. . Have yet to install it.. Because much like my engine, I don't give a shit.
@@maruko7321 probably US dollars because from what i've seen every other country in the world has the sense to just round up to 120 in their pricing lol
Yours is the best video I've seen so far, from other videos, on how to clean, the EGR, GOOD TEACHING, now I can clean my.
You are an excellent teacher ! Please show an easy to understand ways to test an electronic EGR valve. Thanks
From Wikki: *In internal combustion engines, exhaust gas recirculation (EGR) is a nitrogen oxide (NOx) emissions reduction technique used in petrol/gasoline and diesel engines. EGR works by recirculating a portion of an engine's exhaust gas back to the engine cylinders. This dilutes the O2 in the incoming air stream and provides gases inert to combustion to act as absorbents of combustion heat to reduce peak in-cylinder temperatures. NOx is produced in a narrow band of high cylinder temperatures and pressures.In a gasoline engine, this inert exhaust displaces the amount of combustible matter in the cylinder. In a diesel engine, the exhaust gas replaces some of the excess oxygen in the pre-combustion mixture.[1] Because NOx forms primarily when a mixture of nitrogen and oxygen is subjected to high temperature, the lower combustion chamber temperatures caused by EGR reduces the amount of NOx the combustion generates (though at some loss of engine efficiency).[2] Gasses re-introduced from EGR systems will also contain near equilibrium concentrations of NOx and CO; the small fraction initially within the combustion chamber inhibits the total net production of these and other pollutants when sampled on a time average. Most modern engines now require exhaust gas recirculation to meet emissions standards.*
just a great explanation, thank you...
When are you getting the crown vic back?
Kevin Tinajero Should be soon because it needs brakes and I told him it was very dangerous to drive lol. Gotta convince him to give it back to me somehow right ;)
ChrisFix lol thats great cant wait :) !
Your channel is one of the best channels on TH-cam.
Really a great video, well done. I can’t believe that I used to suffer through the “other guys”videos and the endless obnoxious schtick and they don’t even have any helpful information. This is how a video should be done, to all the other guys……… 👍✌
Amateur q. How does hot exhaust gas help cool the engine? Or did i misunderstand?
Alpha Bravo From what I've been told the EGR is an emission thing and has absolutely nothing to do with cooling off cylinders. Hot exhaust gases are ALWAYS hotter than the air coming in the engine. Not sure why he claimed that was its purpose.
The exhaust gases displace oxygen during the combustion process. By routing them back into the cylinders, it decreases the amount of oxygen that is able to mix with fuel. Keep in mind that it is a very small amount that gets mixed in but it definitely prevents the cylinders from getting too hot and makes the exhaust cleaner. I'll also add that this system is not active during wide open throttle for maximum performance and minimum tree hugging so don't worry
Alpha Bravo It also warms up the coolant, besides that only bad for the engine for sake of emmisions.
It prevents overheating, after combustion process. Doesn't necessarily cool them off like he said, but does aid in the prevention of overheating, by stabilizing the air/fuel mixture.
Alpha Bravo The only thing I can think of is that by doing this and preventing some oxygen from getting in to the mix it prevents a potential lean condition which would cause the cylinders to burn hotter. But That should all be carefully regulated in a fuel injected car anyway so *shrugs*. I'm not an expert so I could be 100% wrong.
Hi Chris, it's 12-18-2019 right now, do you still have the C4 ?
Yes
@@chrisfix amazing car, hope you keep it
Omg Chris its like your read my mind that's what code came in my truck 😭
I don't how i can thnk u ...with u, i got to know...that i can also repair an old vehicle (by all videos) and save money which i hv to spent to buy new one nd i can maintain my car myself🙏😁
Excellent as always. Thank you.
Glad the video was helpful!!!
I'm in love with your 'vette.
ComandanteJ Thanks a lot! Such a fun car!

nice corvette man!
A born teacher. Very clear and precise.
I don't think I have this but I learned a lot from your videos keep the channel up ChrisFix you make our lives more easy 👌👍👍👍
why not replace with a new gasket if it is so easy to do so?
Kevin I was wondering the same thing. *Confused*
Kevin maybe an older gasket is more rubbery and molded so it would work better than a new one
It might not be. He'd have to peel it off or scrape it off if it's that bad lol.
Kevin Just like i tell my gf if its not broken don't fix it. She kept messing with everything under the hood and the car wouldn't turn on.
Kevin It is not easy to do. You need to take it off which is going to be a real pain since it is stuck on there good. You need to clean the gasket surface without getting anything in the intake, you need to put the new one on and hope it seals. Not worth all of the effort when I know the original works.
"To cool the cylinders"...I thought the EGR reduces nitrogen oxide emission.
Attila theHun It cools the combustion chamber and when the combustion chamber is cooler, NOX emissions are reduced. The hotter the combustion chamber the more nitrogen oxide emissions there are.
ChrisFix but hiw do exhaust gases cool the. Combustion chamber? They are supposed to be hot, they dont cool down in an expansion chamber or anything...so they are actually warmung up the combustiin gased that enter the combustion chamber...and as the carnott law states: the less ∆temp between motir and combustion gasrd the less energy is produced( this is why cars usully kick harder in autum/winter than in hit summer)
don trump Learn English
@@rronaldreagan have you heard of nos making cars faster?
@@ramyswar296 egr has nothing to do with that.. lower emissions ye but the price is high, bad mpg and slower car in the lower rpm. i blanked mine, got it mapped off and the car is way more responsible after that.
I deleted mine , truck works much better lol no more mess ,!
Viktor P Ford 6.0L Powerstrokes most definitely needs the egr delete and if you buy one ask if the egr delete has been done on it because it'll decrease performance
Increase or decrease?
Clutch The egr decreases power and limits the mileage to around 100,000 miles
I've just done a blank off on my car, much faster and less shit coming out the exhaust
Good call Absolute nightmare on diesels, too.
Chris Fix is my go to channel if I have a problem 😁
I really like your videos. As a DIYer it is nice to find simple and descriptive videos that make sense. Keep up the good work and thanks.
+Will Mogridge Thanks a lot Will!
Don't clean it at all. Rip that junk off, throw it in the trash and replace the egr with a block off plate. The egr just hurts gas mileage and performance.
It does not hurt gas mileage or performance. It reduces the combustion temperature during part throttle operation to reduce nitrogen oxide emissions. The EGR valve is closed at full throttle.
Frankie Bleddyn Not just the west cost, the have the clean air force in georgia. Almost the same thing.
It does reduce power at times, but sending air with very little burn-ready oxygen into the intake reduces the amount of fuel needed for a stoichiometric mix.
guys ist better to remove it
^ Well put!
9:44 Correction : These nutts.
Nope. The EGR actually makes it run worse. It was added in effort to reduce emissions by injecting non combustible particles in the intake, using less fuel IN THEORY. However, EGRs make the engine less efficient and take away performance, while being harmful in the long run. That's why it's one of the most common modifications, especially on diesel trucks.
Such a beautiful car, it's great to see it when someone takes extreme care of his cars
+Saucy Sam Thanks!
@@chrisfix Nah its terrible care not deleting it
Another great video Chris, gonna take off and check and clean the one fitted to my jeep grand Cherokee 2.7 litre diesel here in the UK. Due another service come spring, this time including the fuel filter. Did the fuel filter near 20000 miles ago when I purchased the jeep. Thanks Chris. 😊
Literally replaced my egr value four days ago 😬
Page Mart EGR valves are very bad for your engine it makes it run hotter and decrees engine preformance and gas mileage
An EGR really makes a diesel run worse
I've blocked my EGR off. It's complete junk. After a month of normal driving carbon buildup starts occur and you need to rev it like crazy to get it out. Only saves very small portion of fuel and causes more problems.
I'm 70 ex ENGine builder, back in 69 when I had a SUPERCUDA 440 everything was always spotless there were only 2 grades of gas reg and high test..The cause of all the buildup is EATHANOL IN THE GAS TODAY,it comes from CORN a sugar base !!
@@rayoliver6807 I have a diesel engine
Its been a While, Nice listening to your Pointers, and perfect English.. I do have a P0404 code and I have to past inspection in a few days .. I hope I can clean it and fix it..Thanks Chris..Luis From BK NY..
Awesome and good luck!
I just did this on my 91 Cadi, I failed Emissions. Rated a 2.72 on NO2 test, and the limit was 2.50. Now I pass at a retest of 1.51, with the benefit of better MPG, smoother idle, and my accelerator doesn't have any lag anymore.
Very informative
Thanks!
Where did you get your corvette
can't we use brake cleaner to clean EGR valve

Why are exhaust manifolds always so rusty? Even brand new cars have rusty manifolds.
I'm not by any means an expert, but I'd hypothesize that it's because the exhaust is one of the hottest parts of the engine. We're you to put any sort of coating on it to prevent rust, it would likely burn off, and rustproof alloys like stainless steel might just be too expensive. To anybody who wants to tell me I'm wrong, feel free.
it's because they are usually made of cast iron. Cast iron handles heat very well.
2006 duramax diesel fuel smoke
not necessarily rusty, more like discoloured because of the heat. if car driven regularly, it's all good because any water will quickly vaporize off anyway
believe it ir not, but stainless steel also slightly corrodes, hence the goldish colour on stainless steel headers over time. also discoloration by temperature.
Exmerion heat and condensation
EGR is the devil on modern cars. I hate it
EGR SHOULD BE BANNED. YOUR A SMART GUY. ITS POLLUTING OUR ENGINES. CONGRES!!!
You are wrong! It cools the engine. Learn more auto-mechanics!
EGR top 3 things:
- cools the engine
- lowers fuel consumption
- lowers CO2 emissions
How is this evil, btw?
They are not that bad on modern gasoline engines... diesel is where you have to watch out. Diesels not only pull in more EGR gasses than gasoline, diesel exhaust gas is much dirtier (soot).
Rusu Traian Cristian Egr cools the engine by stopping combustion from happening so if there’s 80% clean air and 20% Egr the engine isn’t able to combust the 20% so that means your car is slower, less responsive, and shorter engine lifespan
DAYHAM!! what a competent, knowledgable, and comprehesive video! THANKS!!
