How to Replace the Spark Plugs and Valve Cover Gaskets on a 2005 Mazda MPV

[@Junk65]

Great video. You’re my MVP when it comes to working on my MPV .

[@HowtoAutomotive]

Junkyard Buzzard lol I like it. Thank you for watching!

[@BobKontak]

Thank you for the thorough walk through. How you get the camera into some of those hard to reach spots is amazing. Very good camera work across the presentation.

[@HowtoAutomotive]

Bob Kontak are use an iPhone and I hold it with one hand and do the work one handed. To keep it in the frame I do all the work looking through the screen on the camera. Kind of like a doctor does.

[@jamesmcoy570]

How to Automotive Yes! As I watched I was thinking ...this guy is like a doctor ...only for cars. Very skilled and precise. Knew exactly what he was doing!

[@thesilentobserver93]

I'm thankful this video exists. But all that just to replace spark plugs? Someone either needs to get fired for being anti-consumer, or a raise for forcing consumers into expensive dealerships for what should be simple tasks.

[@normansmith7806]

Remember the good old days when we just unplugged the plug wires and unscrewed the plugs ☺

[@HowtoAutomotive]

Me too 👍🏻 I miss my old 67 Chevelle.

[@rodneys9805]

for real, this is crazy I sold my suburban and brought a has saver, now I'm regretting it, way much more work on this little guy, then my suburban

[@thesilentobserver93]

Makes me miss my old '91 CRX. Was right at the top of the motor, and super easy to do. Five minutes max.

[@BPoweredLove]

This has nothing to do with the time, era. Many cars manufactured in 2019 have easy to access plugs. But since you're bringing up the past, let me join in! Remember the good ol' days when we had to put chalk on the timing belt to adjust the timing and we had to adjust and clean complex carburetors? Me too

[@someguywithasubie8541]

AH yes , 5 mpg and 140 HP. The good ole' days.

[@pigyear88]

No wonder so many people junk their MPV sooner than other vans. I have one with some problems and I am ready to junk mine when something major occurs. Thanks for the video.

[@chelseabenally4962]

Question did you change the spark plug wires too? If so where did you buy them. I need change my 05 mazda mpv spark plug and I been searching for the wires forever...

[@mrnobody5355]

Bro I just recently did exactly this and your video was incredibly helpful. Just wanted to say thank you. Not a fun job if I may say

[@HowtoAutomotive]

@@mrnobody5355 glad the video was helpful. Thank you for watching!

[@humbertozepeda7320]

The best video in the world,,,very well explained ,very professional.....top ,top ,top. Thank you.👌

[@echosmyth5021]

Oh, is that all it takes to replace the spark plugs? * rolling eyes *

[@pigyear88]

Pretty poor design for serviceability and I have the MPV.

[@BPoweredLove]

Engine orientation takes many more things into consideration than serviceability.

[@businessexpansionstrategie4015]

Thank you Brian for the excellent video. I have a Mazda MVP 2005 exactly like this one, but after changing all spark plugs and new coils I have another problem, the engine knocks and the knock goes faster with acceleration and loses power on idle along with a crying noise like a belt slipping and the engine shuts down. I have checked the oil level and it is good. I noticed there is a leak coming from somewhere from the engine. Do you have a video explaining this kind of situation and what the solution would be for it ? thank you.

[@HowtoAutomotive]

I would recommend taking the belts off. And start the car for about a minute. If the noise goes away it one of the pulleys like the water pump or alternator. If the noise is still there with the belt off then it in the engine.

[@pigyear88]

Thanks for the video, If I got a weekend and a good back then I can try this. I already had mechanic replace the ignition coils 2 years ago. Coils are the only part that broke so far and oil leaks.

[@SteelskinDMC]

4:42 I nearly peed myself. Great instructions thank you!

[@Junk65]

Great instructor! And an Excellent mechanic.

[@HowtoAutomotive]

Thank you!

[@zoefaith120]

I have the same situation ony 2004. I got a skip on cylinder 3 so called. I know it can be a coil or that one plug.if you there it better to fix them all. Like surgery. What would be a decent cost for this motor for parts? After market vs factory ? Labor rates? How long should it take to do?

[@chrisortiz8072]

Should any kind of sealant be used on the gasket?

[@islamicwaylive]

Do you recommend putting on any extra sealer on before or after you put the gasket

[@HowtoAutomotive]

islamicwaylive just a small amount of silicone in the corners of the Cam lobe‘s.

[@islamicwaylive]

Thanks a lot!

[@HowtoAutomotive]

islamicwaylive thank you for watching!

[@islamicwaylive]

Will do. Do you still have the mpv?

[@brandonwilson982]

What size socket did you pull those plugs with?

[@Circuitmountain]

going to attempt this tomorrow

[@HowtoAutomotive]

Super Mayan you will save a lot of money by doing yourself. Thank you for watching!

[@clayguy33]

Just got an estimate for $650 to replace plugs (and fuel flush?) on my 05 MPV. So I guess I'm going to tackle this on my own... Especially since I have this to watch.

You’re definitely Going to save some money. Thank you for watching!

Man. The insulation on the wires from the coil packs is completely deteriorated. Wondering if I should wrap them in electrical tape :/

Do I have to take the valve covers off to change coil #3?

Hi do you have video how to replace left catalytic converter towards headlights In Mazda mpv 2002 I will appreciate if someone forward that video

[@tammymoog8912]

How long or guessing on the hours did it take to take out parts, replace spark plugs and put it back in?

[@HowtoAutomotive]

About 3 hours

[@ElizabethBeauchamp-xv5dl]

​@@HowtoAutomotivefunnnn lol. How long would you estimate for just the front valve cover gasket?

[@HowtoAutomotive]

@@ElizabethBeauchamp-xv5dl just the front I would say about an hour

[@nasr7287]

Mazda MVP!?

[@chrisortiz8072]

Help anyone lol One 8mm bolt almost sheared off completely but it's still enough left to hold on the valve cover. I have no idea how to get it off it's such a small place cant fit much of anything inside anyone ever see this any ideas?

[@GnosisMan50]

I really like this car. I've had mine for 17 years, a 2000, and it still running with no major problems but it's got a lot of rust. I wish I could restore it. Instead, I just bought a MPV 2003 last week with 65,000 original miles on it for $7,000. The price includes shipping from one state to another. I bought it because while this car is a mini van, it's the only minivan in which its length is about a foot shorter than the minivans of today and I prefer this size. I also like the headroom. I can put my bike inside standing up between the seats with space to spare. Most men like trucks, I like minivans. I've done a lot repair myself so I know what to expect on these MPV's My only concern is the condition of the engine and transmission. The seller swears all is good and from the photos, it does, but its not until I get it to a Mazda shop i'll know for sure. It may need a timing belt since I had to replace mine before. Even so, I'm still ahead provided everything else is good. Since 2004, I've put in about 4,500 miles on my MPV every year so my next one should last me at least 14 years.

[@alexbekkala1718]

The mpv uses timing chain not belt.

[@GnosisMan50]

@@alexbekkala1718 I lost sight of that... I just hope the timing chain on my 2003 will not give me any problems... thanks for pointing that out.

[@alexbekkala1718]

@@GnosisMan50 yeah no problem. I have a 05 Mazda6 with the 3.0 v6, and when I open the oil fill cap I can see the chain. I just purchased a used 02 mpv because I'm familiar with the 3.0. only had it couple weeks so far I'm loving having all the extra space. They are really nice looking vans.

[@camryv]

Another minivan which is similarly sized is the 1st generation Toyota Sienna. It also has a 3.0 v6 and 7 seats. The sienna does have a timing belt though. Though the sienna being a Toyota where the MPV has a lot of ford parts (including the engine), the sienna is likely more reliable. I speak from experience of having of both.

[@ivanarroyo6216]

how do you change the rubber on the screws ?

[@HowtoAutomotive]

Ivan Arroyo I put them in a vice and cut the old ones off. Using a knife and a pair pliers to hold still. And then I just press the new bushings on to the screws.

[@TBruce1380]

Wow..... All that for 3 spark plugs....🤣😒😒😒😒 Thanks for the video!

[@HowtoAutomotive]

Thomas L Bruce I know it’s crazy.

[@Nilani]

What I'm learning from this is that you either spend 6 hours doing a change yourself or pay 600 dollars to have a professional do it in 3. Absolutely insane.

[@RyanSollars]

More like $900 from a shop. A friend of mine just got a quote.
