HOW TO: Change Spark-Plugs

[oddball]

Thought I'd add, if you've ever had a problem removing spark plug boots- There is a spark plug boot wrench to make the job much easier.

Anyway, next time you change plugs, use di-electric grease on the spark plug terminal. Not only will this protect the plug & boot from water, this will also make it much easier to pull the boots next time you change the plugs.

Hello all ,I'll add my 2 cents worth . Swivels and extensions tend to crack the spark plugs both installing and removing them . 2 -10 mm nuts to remove the radiator tank and you will have a straight shot to the back plug . Also ,if your socket doesn't have the rubber insert to capture the spark plug ,loosen the spark plug , leaving it installed a few threads and use a 6 in. piece of 3/8 fuel line hose to slip over the plug for removal. Do the same for install . Use a very small amount of anti-seize lube on the spark plugs threads ,less is better in this case .

Yeah, they're ceramic so any lateral pressure on the ceramic shaft is, well, potentially dangerous. My opinion you shouldn't be putting a lot of pressure on the plug in the first place (I understand TPI MONTE indicated he hadn't changed his in 7 years... so). Given the rather light torque required for the plugs, if one is careful, you shouldn't have any problem.

No spark plug boots on the KJ!!

 

[oddball]

True. It also works for coils & glowplugs.

 

[CRD Joe]

What are spark plugs?

 

[oddball]

There are 6 of them on real KJ's.

What are spark plugs?

It's a form of contraceptive so your 3.7 KJ doesn't become pregnant.

Oh, you mean those trucks that get 17 MPG around town while I get 30MPG?

Oh ya, those trucks. I get it. Thanks.

 

[oddball]

Yeah, you keep telling yourself that.

 

[CRD Joe]

Yeah, you keep telling yourself that.

Last tank. Combined city highway, around half and half was 30.8 MPG bubba!

Ive gotten 38.8 MPG on highway trips before. I can keep telling myself that all day long!

Youre the oddball remember!lol3.gif

The ones that don't have torque converter and EGR issues

The ones that don't have torque converter and EGR issues

Like Mine. Suncoast and SEGR and Provent.. Everything but the SEGR was there when I bought it.... lol3.gif

 

[ThunderbirdJunkie]

Hmm. ThunderbirdJunkie needn't make any modifications to his powertrain for reliability

Silly diesels

(Of course you know We keed)

 

[Liberty06]

I did it! They were gapped waaay out of line as the end was burned down on the igniter.
I used platinums and wow what a diff...

I have a question about the Autolite APP5224 plugs. The metal ring seal isn't already on the spark plug, its in the box. Each of the 6 plugs I bought are like that. Which way does this ring go on? Here is a pic of what I am talking about :

You must be registered for see images attach

See there is a flat side and a rounded kinda side...

just like you got it the small part is up in the air

 

[RageOfFury]

just like you got it the small part is up in the air

I had a feeling it goes like that. Thanks!

 

[mag03kj]

ya when i changed the sparks in mine all of those things where off the plugs

You must use a special gapper(plastic or compsite) to gap platnuim plugs our you will destroy them.

Always go by what the emission sticker under your hood says for plug gap.

how will this destroy the plugs using a standard (metal) gapper?
