help: changing plug leads on a 94 EF

Hi all,

I can't for the life of me see an easy way of changing the plugleads on my 94 EF,
short of taking off the intake manifold!

The coil pack is directly below the intake manifold, jammed in a tight space.
Getting to it from underneath is just as bad as getting to it from above.

The Gregory's book i have has no useful information what so ever about changing
the leads.

Is there some trick to doing this?

I've done it on my uncles EF, you need the car to be on ramps up front because you'll need to get to them from underneath (i don't trust the jack). Anyway take off you inlet piping and undo the cable ties which bundle the leads in sets of three (original ones are like this) now get under the car from behind the passenger front wheel, this the only way you'll reach the coil pack. Easiest way is to remove & replace one lead at a time. Your gregorys book should tell you which pin on your coil does what cylinder if you run into trouble.

are the new ones you have numbered? pull all the old leads off as AU2FalconS has said, then figure out which new lead goes on which cylinder, and feed them down from the top one at a time, going from front to back or back to front to make is easier. if you get a torch and look between the inlet runners you can see that the coil pack has the correct lead number printed on it, just pop the lead on the correct pin and then continue...takes a while but what choice have you got?

you can get them from the top of the car if you are a skinny runt like me and are prepared to risk scratches from the edge of the intake manifold :)

They sure are.

I think the first step for me is to go buy some ramps.
I dont trust jacks either :)

I had it up on jacks, but I couldnt easily see much at all.
I also had a go with the airbox out. still couldnt really get in to get at it.

I'll get some ramps and see how I go :)

Thanks for all your help guys :)

I dunno about you, but theres no way my hands could fit between the intake runners. I tried to fit a few fingers and they almost got stuck.

Easy way is to get some ramps and take your time doing it. Even from below i scratched my arm big time, and almost got stuck a few times.

P.S. im 6'3 and my arm span is around 6'5, long arms in tight spots dont go to well. Have fun

Remove the air cleaner box and you can reach the coil pack from the front. Have done this once on mine ---no scratches
