What am I missing? I can't get the 5/8" plug socket onto the plug. My new plugs are 5/8", could the old ones be a different size?

 

what's the replacement plug and part # that you bought? You can pull out the plug heat shields with a pair of pliers, just twist a bit and pull straight out. You really don't need them and I think they cause more problems than they are worth.

 

Hi eyebrowski, so what you are saying the 5/8 socket is too small?

Do you have a 13/16 spark plug socket?

Try this first, if it fits see what spark plug it is (brand and type). Check it to make sure you have the right plug for your truck. You didn't say what year your truck is and size of motor.

Check this as well..... www.dodgeforum.com/m_837308/tm.htm

Let us know

Wrong size. It is either 5/8ths or 13/16ths, so you don't have a lot of choice here. Make sure you get both in your tool case. I remove the heat shields because rust and crud gets in there. I put them back, but felt like beating them with a hammer!

 

I had the same problem with my socket not fitting. Make sure you clean out the heat shield tube with compressed air if available.

I found that I had to use a regular 5/8 deepwell socket on a couple of the plugs. It was a different socket manufacturer, too.

 

haha i hate to say this but i had the same promlem. i went to do a turn up long storie shorty about 5 hours later and an air hammer i had the spark plugs out. you have to get the metal jacket that is around it off. it is the a plan in the @$$. save your self alot of time and take it to a shop. trust my i would of done it first if i know it was going to be that hard. and i like to do evey thing myseft hope this helps

 

Take you truck to the shop to change Sparkplugs???? Are you crazy............

There not some mystery socket, find one that fits and take the bastards out

 

They aren't that hard to do as I've done mine a few times. I don't remember what size spark plug socket I used but I have a set of a couple from craftsman and maybe other places not sure if they are all Craftsman or not and it was one of those that fit. I've got several though. Go to walmart. They sell like a set of 3 as I just saw it the other day. It's a good chance one of those will fit.
