2005 - 2010 Honda Odyssey - spark plug and coil replacement - how to 

+chris fettig Good call on extension. On 2010 Odyssey - there is not an allen bolt - just an Acorn nut on top of existing threads which stay in the block. Easier to remove and (presumably) easier to line up putting COP back in.

jky. Sorry but I am not a mechanic so I can not answer emphatically. However, if you check out Honda J Series V6 Valve Adjustment (Part 1) -EricTheCarGuy you will see just how involved a valve adjustment may become. The cover is actually quite straight forward in terms of how it mounts to the top of the motor (see my video around the 2 minute mark). Also notice how much of the engine the cover hides. Hard for me to believe they wouldn't remove it to do all the work you listed. Regardless of what they may or may not have done, I think it would be easy to fix. My question to them would be if I drove the van in with a properly closing hood why wouldn't it be closing properly now unless something changed during your servicing? It should be a quick item for them so I would be nice and polite and ask them to treat it as a customer satisfaction issue. Otherwise, I think you have every right to flame them on any reviews. Good luck!!

We caught our dealer mechanics lying to us about things they'd screwed up on a few occasions. Usually it's three strikes you're out but for them it was five. Never again. My son is becoming a pretty good mechanic while working on his 94 Honda Accord. I think I'll trust him with changing out our spark plugs on our Odyssey. Dealer wants $750. They're crazy. And they're liars.

Good idea. I added it to the description too. Plug should be tightened to 18-22 ft-lbs.

I think you mean a torque wrench? I did not own one at the time but to do it by the book you should use a torque wrench.

Hi Steve, shop manual does not indicate the battery should be disconnected. Do you have a reference? Also, I would be much more worried about getting caught in the drive belt and the electric fans than getting bit by a spark plug firing.

@@krgetler as a general rule... I always disconnect the battery.... most of the manuals I have for my vehicles have that at the top of each section when working under the hood. It's generally a good practice and yes.... keeps fingers and stuff intact ... to be on the safe side. You could also spark a fire if there is a leak etc... just a safety practice.

if you do a " search"...there are varying answers... I just did one. most mechanics say to disconnect the battery and most DYI say it's not necessary but it wouldn't hurt... I always try to be as safe as possible... I wear safety (shooting glasses) when I mow the grass lol

Regrets Rodney. The engine plugs are completely symmetric from front to rear. The process/orientation on the front plugs is the same as on the rear plugs - other than having less room to reach and swing wrenches. I used a hand mirror to see around the rear of the engine to make sure everything was installed correctly.

Which coil is which number?

Clyde Ng Hey Clyde, yeah, 11 year old camera man could use some training. Based on your feedback I cut his pay, dropped his dental coverage, and sent him to bed without dinner. Hope the video helped anyway.

Like you comment jajaja

Ok

Hey Seth. Thanks for the video pointers citizen. When you have your spark plug training video complete let me know and I'll delete mine. Hopefully your viewers will be more respectful and appreciative. Everyone else was so cool.
