What about 1800?

That's also an interference design (i.e. valves will hit pistons if the
belt fails).

Also to clarify the surgeon's statement, it's only the SOHC 2.0l engine
available in the US that is non-interference. The 2.0l DOHC Zetec engine
is an interference engine.

Paul, are you *sure* that the 2.0l DOHC Zetec engine is an interference
design?

The Focus service manual says this as part of the timing belt installation
procedure (Section 303-01D: ENGINE - 2.0L ZETEC-E):

-------begin quote------
Turn the camshafts to ignition position on cylinder number 1 and insert
the special tool into the camshafts.
-------end quote------

This is with the crankshaft immobilized with the special tool: "Timing
Peg, Crankshaft TDC 303-574 (T97-P6000-A)".

It would not be possible to safely turn the camshafts from an arbitrary
starting position with the crankshaft at TDC if the engine were an
interference design.

Whether the engine is an interference design or not, it is wise to follow
the manufacturer's recommendations on inspection and replacement of the
timing belt and associated components.<!-- ~MESSAGE_AFTER~ -->

Section 303-01D actually refers to the 2.0l Duratec engine.

My copy of the Ford manual states that you "Turn the camshafts to the
ignition position on cylinder No. 1" THEN "Rotate the crankshaft to TDC
on cylinder No. 1".

Of course if you are just changing the timing belt, you wouldn't want to
rotate the crank or the cams with the belt off and there would be no
need to do so.

On US spec 2litre SPI engines belt breakages dont hurt the valves.

On *all* the other engines you will have bent valves. That inclues the 2
litre SEFI zetec E (i.e. the one us europeans get)

Not in my manual. I'm quoting from the CD-ROM version, part number
FCS-12551-00C15 May 2000, Version 15.0, which I have here at work.
I also have the printed version at home:

"
Section 303-01D: ENGINE - 2.0L ZETEC-E
Section 303-01E: ENGINE - 2.0L SPI
"
The CD-ROM and the printed versions that I have match exactly, at least
for the stuff I've looked up so far.

Agreed, but so far no one has come up with any text from a Ford
publication that warns against turning the crank or cams without the
timing belt attached, which is a pretty good indication that the 2.0l
Zetec-E is a non-interference design.<!-- ~MESSAGE_AFTER~ -->

That's really interesting because here in Turkey, I have been said that the
2.0 Liter DOHC engine is not an interference design. I will clarify this and
report here.<!-- ~MESSAGE_AFTER~ -->
 >> Stay informed about: Focus Timing belt change 

Re Ford Focus timing belt.
I contacted four Ford dealers in my area, and they all said the there IS
clearance between the valve and piston should the timing belt fail on a
Zetec engine.
However it would still be advisable to change the belt at the 100,000 km
mark.
I just hope they are right ???

My Ford Focus shop manual says for the 2.0l Zetec-E engine:

"The timing belt must be installed new after 150,000 km (90,000 miles)
or after 10 years."

 > I just hope they are right ???

Why shouldn't they be?

Anyway, if you change the belt on schedule you won't have to worry about
whether it is an interference engine or not. I'd also change the camshaft
seals, water pump, and timing belt tensioner while I was in there.<!-- ~MESSAGE_AFTER~ -->
 >> Stay informed about: Focus Timing belt change 

150,000 km this gets better. I am using Haynes repair manual available in
Canada and North America this recommends 100,000 km but I like your manual
better.

I know the belt change interval was prolonged for the 2 litre zetec a couple
of years ago, as well as the service intervals that then became 20.000 km. I
got a new service book with the new intervals, unfortunately the car is not
at home just now, but I will check more exactly later and come back.

We are talking about the 2.0l Zetec-E as supplied in the USA and Canada.

From what I have been reading here, the 2.0l is different from the 1.4l,
1.6l, and 1.8l Zetec engines (which are not available in the USA/Canada).

So, I think I will take the word of four franchised Ford dealers, thanks.<!-- ~MESSAGE_AFTER~ -->
