How to clean or replace EGR Valve: 2003- 2008 Mazda 3,5,6 and Tribute 2.3L 

This is the only video i saw that covered the exact motor( 2.3 ) of my Ford Escape 08. Huge thanks for this video !!!

This is one of the BEST vehicle repair videos I've seen! Great detail including sizes and the zoom in quality with perfect lighting and no shadows is what separates you from the others. Plus, you fast forward or skip showing the tedious wrench turning making your videos an efficient and effect use of time. Based on the quality of this video, I will SUBSCRIBE to see your other stuff!

I used a Valvoline carb and throttle body cleaner to clean the EGR on my 2003 Mazda 6, and made it look almost brand new and shiny.

Excellent DIY video. Creative socket extension to get to an obstructed bolt.

I was stubborn and didnt wanna remove the radiator hose. Mainly cause I wasnt planning on getting the EGR valve today but I did a side job and ended uo getting the money to get the EGR valve. I didnt wanna lose a lot of coolent cause I only had half a jug left and I didnt even know I had to remove that little hose to get it out. I literally just went in blind and watch a bit of your video. I saw I was on the right track but didnt bother taking off the radiator hose. Thanks for the vid dude

Great video! Going to try that swivel socket combo tomorrow on my 2008 ford fusion. Its basically the same as the Mazda 6.

I had to change out my egr on a 2008 mercury mariner, all the posted videos didn't look ANYTHING like mine, yours did. While not exact, the parts that mattered were spot on, like the coolant port directly in front of the second screw. I also used your makeshift tool idea to break it loose. I ended up untwisting the screw out by hand the rest of the way.

great production on your video. concise and very helpful.

My brother translates this because I will write it to you in Spanish!!! Busqué muchos videos para saber como llegar a la EGR y este es el mejor. Te felicito por la manera tan sencilla de explicar y de grabar. Mucha suerte y sigue grabando, eres una máquina 😎👊🏼

I got it out with a standard quarter inch ratchet and shallow 10mm socket and didn't need to take out the whole battery/terminal. Trick was to take the Black Sensor piece off the top of the EGR Valvw, it's 4 screws this goves you much more room to the bolt.

Bro I gotta think you.. It took me n my brother hours to try n get that bolt off.. Thanks bro. You the realist 😎💪

Wow this was a great video my son just purchased a Mazda and it had a egr problem watching this video helped me complete the job thanks a lot bless you brother

Subscribed. You described the symptoms perfectly for the people who dont know. It can also cause misfires and rough idle loss of power in acceleration

Thank you very much for posting - very clear.

Good vid!!! I've had great luck with maf cleaner!!!

Thank you... ur video finally help me about my issue

chiesel gasket remover , or engine degreaser then brake clean , that is the stuff i would use !! good job

Awesome that you did this!

What a pia this was to do. That bolt was so stuck on mine. Needed to remove the hose in front of it that was held on by 3 bolts. Meaning battery removal, tray, motor mount support. Finally got a straight shot at it with that hose removed. His contraption didn't work even after trying all morning. Now, hopefully all this work putting it back together will reduce the rough idle problem I have. Let's see.

Incredibly clear and precise. Huge thanks.

Great video thanks

Excellent job

Thanks Anthony. Looks like tons of fun. After seeing the insides of this EGR valve I am wondering if you decided to do this job because of a code P0401 or because you noticed the cold weather RPM part you mentioned. SInce you seem to know your GH1s I wonder if you've ever separated the front lower control arm ball joints (both of them).

That was a great video

We use mazdamenders jiza clean to clean the carbon off/out on the EGR valves, inlets, throttle body and engine bays, good vid to a very fiddly job.M-m

Great video

Thank you very helpful

Right now you're looking like a genius in my world. How the heck did you think of that combination of socket parts to get that back bolt

Hi, after watching this video I'm trusting you on this! I have a couple questions about my Mazda 5 2L Diesel 2007. I'm by no means a car guy, at all, but I learn quickly and I have a fair amount of mechanic friends who can help me out with the technical stuff. Right now, I'm just trying to get a better picture of whats wrong with my car. A couple symptoms are: Sometimes becomes incredibly weak, I need about 4000RP to be able to change to the next gear for the car to move at all. When the car behaves that way it also puffs out really black exhaust, which from my understanding means the fuel/air ratio is off. Now, I don't know if it's too little air or too much fuel but I've checked the Air Flow sensor in the engine compartment and that one is fine. Some sources say it's the EGR Valve and others say it could be an injection problem or the lambda sensor. The weird thing though is that the car returns to normal after an undefinite amount of time. Any thoughts? Anybody can give their thoughts. :) Thanks guys!

I have a 2008 Ford Escape with the same engine - I figured out a way to remove that difficult bolt. First, remove the air box cover, the battery and battery tray. Now remove that coolant hose - it'll dump a bunch of coolant so put some rags directly underneath and a tray to catch anything else from spilling onto the ground below. Now to get that bolt out, you need a bench grinder or some sort of grinding tool - find a cheap socket extension and grind it down about 25% thinner, then take your 10mm socket and grind it down so it is shallow, just deep enough to go over the head of the bolt (take the front bolt off to check) - now you should be able to easily get that in there and back that bolt off! I spent many hours trying to figure this out, including using the exact method mentioned in this video, which did not work for me (could not get enough torque on the bolt to turn it at all).

It helps to drain the coolant first and removed air duct assembly

hi, whether in mazda 3 2010 - 2.0 egr is in the same location?Thanks

Damn so it was this the whole time, I’ve replaced so much stuff tryna fix a rough idle and car spuddering while accelerating, I changed maf sensor, air filter. And fluids and everything.

Question, will a bad EGR valve cause coolant to be forced out of the reservoir overflow at high speeds? Car is an 04 Mazda3, thanks!

Excellent video, mines throwing a engine light for awhile now and I’m going to tackle this after doing the same on my defender. What’s the odds of the motor in the egr being stuffed from pushing a stuck valve? Don’t want to really strip it and reassemble without a degree of certainty that it’ll still open and close once cleaned.

If you want to check the egr for leaks get small paint brush and brush some washing up liquid around the seal and it will blow bubbles then you can see if needs tightening any more when tight just rinse off because it can crowled on Some metals. I wondering you could use one of the flexible drill Extensions, I know you can get sockets to fit then

What is that hose that connects to the middle of the big intake hose for? The one with a blue terminal.

Hey awesome video it helped me a lot I got the exact same car! Just a got some questions. I took mines out cleaned it. I just got the code again today after 2 weeks of cleaning it, do you think I need to replace ? and also when I’ve been running my car for like 15-20 minutes I get a beeping in my car, do you think it’s related ?

Cordial saludo, tengo un Mazda 6 con 100 mil km, cada cuánto se debe limpiar está válvula? Cuáles son los problemas comunes que se producen cuando está válvula está sucia?... Te agradezco, excelente día.

Can a bad EGR prevent a car from going over a certain mph if its defective

My plastic intake manifold melted where the exhaust gas enters via egr valve. I wonder if it’s a failed egr or something else. What do you think?

It might be easier to take it off from throttle body to make a room to take off the EGR valve rather than battery and battery box with a lot of cable and fuse box (means a lot of work), when throttle body off, you can also clean it as well, make it part of the job. Have you tried spray it with CRC intake cleaner to clean the EGR? Which one is better compare to brake cleaner?

thank you gooood

Hello my mazda 5 2007 diesel start normally but will not receive gas at all barely reaches speeds up to 2000 rpm, stinks and smokes gray-white smoke, after waiting a while everything is normal. Is it an egr valve?

Does anyone know how much coolant you lose disconnecting that hose?

A+

Sirs,, based on your respective experience, would it be better for my 15 years duratec engine if i just block these two holes? Would it give a better iddle & better MPG if i block these holes with thin metal plate? Thanks

Thanks for the great video. By the way your valve cover gasket is leaking😅

I did this job, just replaced the old with a new EGR, on a 2008 Mazda 6 with the 2.3. I'm here to warn ya.....Buy a small tube of water pump gasket maker. Permatex or whatever. And put a consistent thin bead of that stuff on both sides of that crappy thin metal 'gasket.' Finger tighten it, wait a day, then torque it down. Why? Because coolant flows through that EGR housing. That's why. And be very very very careful about working that difficult lower bolt back in. Mine crossthreaded even though I thought i WAS being careful. Couldnt get it to go more than 2/3 of the way in. So I ended up having to use washers under the head in order for it to hold down the EGR nice and tight. Because wouldnt you know it thats where the port on the head for the coolant is. SO the first time I tried this it was leaking coolant and I had to re do it with gasket maker. I even put high temp thread sealer on that bottom bolt because it looked to me like that hole actually may penetrate the water jacket in the head. Couldnt be sure but wasnt taking any chances. My second go at it has held up with zero problems.

You can use the power foam from amsoil to clean the EGR valve...it is the real magic, it will restore it to its original condition.

Scottie Kilmer said STP throttle body and air intake cleaner is fine.

Obd2 reader says EGR system failed, I'm noticing an increase in fuel consumption but no check engine light. You think it's worth checking the EGR and maybe do a bit of cleaning?

So what does it mean when you take the egr valve off and clean it and put it back in and water pours out it? Replace egr valve? It wasnt leaking prior to this just had the crappy idle and rough running conditions.

I just got my egr valve replaced but it still gives me some issues.... it drives fine at first like I'll go to a destination like the store for 30 minutes and crank it up and it acts differently like a subtle shake and some gas smell on the ride home.... any suggestions?

Hey Keeper, guess what, I am having having the same idle issue again just near 1.5 years later. Had the Stealership do the EGR replacement in Dec '17 and guess what its doing the same idle issue with the strange smell of rich fuel smell. I also have erratic RPMs sometimes when I go into neutral. I am fixing this one more time and it should last me another year. Just long enough for me to go Honda or Toyota and never buy Mazda ever again. Thats 2 damn cars (Tribute and the 3) that have plagued me with idle issues which were tough to fix.

What is supposed to be on the square blank plate just above the Egr valve. I have a 2011 Mazda 5 and it is leaking coolant from somewhere in that area.

Would the antifreeze leaking from the hose cause any damage to my car?

Did you do anything to clean out the wd40 and brake cleaner from inside the EGR? Since those are degreasers, would it wreck things to leave it in there? Do you just wipe it out with a microfibre rag, or dare I saw spray bottle a tiny amount of water to rinse out and then dry?

Mr muscle oven cleaner as long as you have no rubber on there, it’s cheaper and works pretty quick then rinse and repeat

Does coolant not go everywhere when you disconnect the coolant line?

Can it be cleaned by just removing the 4 screws at the Top of the valve???

Good jod

Anytime I do cleaning of parts like this I always use MAF sensor cleaner, TB cleaner or electric cleaner, cleans really well, dried fast and leaves no residue

Hey, how long would you say it took to replace the EGR valve?

Mazda was thinking clear when they put EGR on this location, but they were drunk when they put it on 1.5 engine in JDM first gen Mazda

Hey man ik u were trying to help but i would find the video more usefull if u shown us how to clean it

That adapter though

Believe it or not, i heard, oven cleaner removes and cleans the carbon.

the engine setup is not the same on a Mazda 6, that egr valve is mounted differently.

Did bro just say nitrous oxide

Little different than 2004 mazda 3.

I bet a mechanic would charge $900. to change that EGR value.
