Matt Payne finally changed my plugs! they were done up so bloody tight i had to get someone to help untighten them. yeh we do have the diesel models over here. next car im getting will be a diesel for sure! once again thank for your video. really helped getting the plugs out
Nice work, Katie! You should be proud of yourself for doing this on your own. I hate it when people over-tighten stuff. That's what torque wrenches are for! You're very welcome, and I'm glad you found my video helpful! BTW - you can download a factory service manual from the "About" tab on my UA-cam page...it is for the U.S. version, so some things will differ...but it may prove helpful for other stuff that is not country-specific. Thanks for watching!
I See this in so many videos. Improper use of DieElectric Grease. Do not do this. you can smear it on the inside of the boot to help sliding on and off, but to not put it on the contacts. It is NON CUNDUCTIVE. IE DieElectric. This will make you Vehicle run like its missing.
Antairus King That's interesting....thanks for sharing that. I've actually never heard that before. In fact, if you read about di-electric (silicone) grease on WikiPedia (not that this source is infallible), it actually says that di-electric grease is commonly used on spark plug contacts without conductivity issues because the boot-to-plug connection is usually tight-fitting and will displace any grease caught between the two. I'm interested to know if my vehicle would run any different if I cleaned the grease out of the spark plug boots. It's running well now, but perhaps some grease contributed to poor performance in the past. Who knows.
Yes remove it. I did this to my Dodge ram 1500 Hemi. 16 Plugs. Ugh. It ran so poorly that it was throwing bad EGR Codes. I will never doo it again. It would cut out and die when I let off the gas. I had watched a video of a guy doing it. Ran fine before I changed plugs Ran like crap after I changed the Plugs. I pulled every plug removed all the Die Electric grease re installed plugs Ran fin and has since then. Now This is common practice for me on my Can-Am commander Side By Side So I figured it wouldn't hut my Truck. Boy was I wrong. The Truck must be way more sensitive. I actually spoke to a master mechanic about it and he said you would not believe how many people bring cars in after doing this. He said he cleans them and then they run fine. Its really designed to go on the inside of the boot not the contact to help it slide. Just use a Qtip and smear a little on the inside and not the contact. I think you will be amazed if you clean them out. By the way its tough to get that out. Electrical cleaner does not work well on it. If you are still having problems I would certainly remove it. BTW thanks for all the videos they have been a great help. I just bought my Daughter a Rodeo and your videos have been invaluable.
Antairus King Cool, thanks for the information....I will definitely keep that in mind. And you're welcome...I'm glad you've found my videos helpful! I think Rodeos are really cool, and they are safe - I got badly rear-ended in my previous 2000 Rodeo (I was sitting still at a light, got hit by a BMW going ~45 mph), and my sister and I both walked away unharmed. The Rodeo got totalled because the frame as bent, but we were not harmed at all. You should feel good about having your daughter in this vehicle...with a little TLC and proper care, it should serve her very well. Thanks again for the tip!
I am curious if this fixed your missing problem with your isuzu. I have a 2002 axiom with the 3.5 engine. It appears to be almost identical. Regarding putting "other" brands of plugs in these engines. It just isn't a good idea. There is a system on these engines called ion sensing. Only the proper Denso and Champion spark plugs support this system. I made the mistake of using autolite plugs in my axiom and had a low end miss the entire time they were installed. I was chasing the problem (engine missing) in other directions. Took it to a shop and had a BG injector service done and they told me flat out the spark plugs I was using would make the engine miss. I changed them out to the correct plugs and the problem went away. 30,000 miles of an irritating rough running engine vanished.
***** The new plugs seemed to make an incremental difference in the engine's performance. I think my issues boiled down to not one single part, but a multitude of parts that needed replacement. Since the spark plug replacement, I also replaced the fuel filter, cleaned the mass airflow sensor, and ran some Techron through the fuel system, and each of those things seemed to help the engine run even smoother. For the most part, the vehicle is running quite well now. With regard to the ion sensing ignition system - I have read that non-OEM plugs will cause the symptoms you mentioned, which is why I wanted to switch back to the OEM Denso plugs. However, I have read posts by a former Isuzu mechanic who says he uses the Autolite plugs with no adverse effects, so it's hard to say what is really true. I figure that spending a few extra dollars for the OEM plugs is good insurance against possible issues, so that's what I decided on. Thanks for watching!
Thank you soooo much! Changed plugs on my sister's Rodeo Sport. That one plug was a doozy! My extension was too long and had to fish the socket/plug out w a screwdriver, remove the rubber gripper inside the socket so it'd let go of the new plug, poked the socket off w the screwdriver then fished the socket out w the screwdriver. Dang! I'd like to shoot whoever thought that configuration up. That plug looked like it'd never been changed and the boot and plug were covered w oil...uh oh. Again, thanks!
NO to using the dielectric grease!!! It’s non-conductive, that’s why your vehicle runs poorly. PLUS, don’t put anything on the spark plug threads, there’s already a special coating on them from the factory. You’ll never get proper torque readings if you put anything on the threads.
Thanks for posting! I will tackle this project this weekend!
elconquistador8302 No problem! I hope it went well for you. Thanks for watching!
thanks for this video. now I can have a go at changing my plugs in my Australian model 😊
Awesome! You guys are lucky in Austrlia...Isuzu sold diesels there, right? How'd your plug replacement go?
Thanks for watching!

Did this help your rodeo run better and feel less “Sluggish”
how did you get your extension out? i cant get mine out
Thanks Matt

So no Bosch

Ok
Where is the OEM torque spec?
awesome info!! Thanks!!
You're welcome - thanks for watching!
Your comment on cylinder six's boot being a different size just saved quite some time in diagnostics. Much appreciated!
