Default Replacing Spark Plugs on a 2.5L

Hey guys, I've been searching for a tutorial on replacing the spark plugs on my 2.5L 2000 ford ranger on the forums but I can only find the 4.0.

Getting to the spark plugs is a royal pain and I don't have any tools that can reach behind the intake manifold.

Do I just remove the manifold to get to them?

Yup. That's the easiest way the previous owner said you can change them. Be careful not to break the intake manifold bolts like he did...they are near impossible to find. Unless you wouldn't happen to have an extra one or two laying around? lol

I was able to use a spark plug socket with an extension and a universal for them.

I have done plugs and wires twice now( I used Bosch plugs and they were trashed in 8k miles and i used the cheap wires without the hooks which made the job a total pita).

You want to use on MC or autolite DP's and make sure you have wires with the hooks or else only buy MC or autolite wires( they come with the hooks)...........I could change all 8 plugs and wires in less than an hour with the manifold on.

The plugs are real easy the wires are what is a pain. I used 2 6" and 1 3" extension I believe and i had a swivel on there also but you might not need it You obviously need the 5/8 sparkplug socket. make sure you use antiseize and put the grease on the plug wire conection. just feed the socket down thru the openigs in the intake and it is not and issue......

an extension and a swivel are very helpful

you do NOT need to take the manifold off

and be sure to get the good wires with the hooks.....makes things a WHOLE lot easier
do NOT get the cheap autolite plugs.....they last 10k miles if youre lucky

take care of your truck and it will take care of you

modelageek...Did you replace the plugs without taking off the top half of the intake manifold? I have AC but just can't see proper openings for getting socket and extension thru. Am I missing something here? I would like to change the plugs myself(never had a car where I couldn't) and the $230 labor I'm quoted doesn't thrill me. Thanks in advance for any help from anyone.

It's pretty much like that with all of the four bangers. A spark plug socket, various enxtension lengths, and a universal will get the job done. Pray to God the wires have the plastic hooks or life will not be good.

ive heard you can pop off the old hooks and put them on the new wires, this is true isnt it?

You can reuse them if the new spark plug boots are shaped correctly. I'm not sure if you can just use them on any old spark plug wire you want though.

This is a well vetted topic. The bottom line is if you are a DIYer, buy a set of Autolite wires. They are about $27. Also use Autolite or Motorcraft DP's.

my engine ate holes in Bosch DP's in less than 5k miles.........like I said this is all well vetted topic....
