Totally Off Topic. Anyone ever changed the coils on a Fiesta

As topic.

I am sure that someone on here has the info or knows where to point me .

1300 cc 02 Reg Fiesta endura engine. Injection.

How do you remove the ignition Coils. "Just unbolt it" it says in the
Haynes manual.

It is mounted behind the engine under all the injection stuff. The Haynes
manual just doesn't mention how to get to it. What to remove or how.
It could be me, I must be missing something.

Any help welcomed.

TIA

Gary

Ahh, Haynes manuals.

I can't answer your question, but it it totally typical of Haynes manuals.

They all seem to assume you have then engine out of the brand new
vehicle, on a bench.

"simply undo the four bolts retaining the exhaust manifold"
Bwa ha ha.

You need to break your arm in 3 places just to be able to touch them,
never mind get a tool on them. And even if you could, they will be
seized solid and corroded, so they will round off when you use the
correct socket. Hammering on the next-size-down socket works, but the
head will shear off as soon as you apply any torque. From there, it
just goes downhill.

I glanced at a Haynes Ford Capri manual is a shop once: it was actually for
the US Ford Mercury Capri, left hand drive with air conditioning.

And don't forget the infamous, "Re-assemble in reverse order."

I'm glad the most complex mechanics I've done is basic servicing on a Honda
CB175 and replacing a car battery.

Symptom of coil failure is heavy mis-firing at wide throttle (could also be
a plug or lead breakdown, but most likely the coil). I have replaced the
coil pack (probably similar to yours) twice on a 52 Ka Duratec, where it is
relatively accessible. It is fixed by four Torx screws, which you can't see
on the Ka. The "cheap" one failed after about a year, and the Ford branded
one has kept going for 3 years so far. While you are there, you will
probably want to replace the plugs and leads (at least one of the latter
having been destroyed during removal).

It is a good idea to set the gaps on the new plugs at about 90% of the
recommended value, thereby reducing the breakdown voltage across the plug
electrodes and easing the stress on the internal insulation of the coil unit
(and everything else). These coils seem to have been designed with an
over-optimistic view of the basic physics of high voltages, and seem much
more prone to failure than the old design using a single (much larger) coil
and distributor, so anything you can do to reduce the stress on them will be
helpful.

Good luck!

A few years back VW reduced to a single supplier of Coil packs as fitted to
some Golfs and Passats, then the manufacturer made some minor change to the
way the coils were made and the whole lot failed after 10,000 miles or so!

uk.rec.cars.maintenance might be a better bet.

So saying, on most cars COP are accessible after removing any engine
cover. You don't usually have to remove any of the 'injection stuff'.

That is the symptom I have got but i cannot get to the pack. I hoped I was
doing something wrong and there is an easy way to get to it which I had just
not sussed out.

Why bury it that way? On the zetec it is right in front of you. I cannot
even see how to get the connector off. I did think of mounting the new
coil in an easy to get to place but without the low tension connection no
hope.

Anyone know how to remove the connector at fingertip, in reverse and without
seeing it. ( Seriously, I would like to remove the connector but cannot feel
the release tag/ clip as I don't know what I am feeling for)

Cheers

I rebuilt a Fiesta years ago but it won't be like yours now I shouldn't
think.
What I do know though is that these instructions in the Haynes manuals often
do just say such daft things, and you end up having to be very good at
modifying spanners and sockets and socket sets, and very handy at working
back to front and upside down standing on your head with a mirror and four
spare hands. (On an old Micra that needed a new timing chain, the manual
just said 'undo the crankshaft pulley - but the nut/bolt end was hidden in a
recess in the chassis. I had to take off an engine mounting and jack the
car up and lever the engine down before I could get a spanner on to 'remove
nut'!) I'm sure they often write this stuff when they have the engine brand
new on a bench out of the car.

You may find that enough lateral thinking will help you get at this, or even
bypass it and fit one with longer leads in a more accessible position.

Good luck,
S
