Looking at buying a nice panther black Y reg 2001 Mondeo 1.8 Zetec, seller says it's a cam-chain jobbie, says 'Zetec' on the boot lid and 'Duratec' on black plastic engine cover, and I can see a cambelt that looks shiny and in need of replacing, service book shows no stamp in the schedule for cambelt replacement.....it's done 80k miles so I'd replace it yesterday!!! Should I worry that it says Duratec not Zetec on that engine cover? I thought I knew it all but you never know.......any feedback from Mondeo anoraks greatly appreciated.......

'Zetec' is the trim level. 'Duratec' is the engine 'sub-brand' that Ford are currently using for these petrol engines. It will be a chain-cam engine. The shiny belt you can see is not the cambelt, its the serpentine belt which drives the alternator, PAS and waterpump etc.

Thanks for the quick reply mate. Certainly put my mind at rest!
|
Just to confuse the issue ,all Zetec/e/se engines are belt drive cam whatever car they are fitted to.All Duratec engines are chain cam engines.

I wasn't aware that the cam belt was visible without removing a cover.

It's not, as Aprilia says he was looking at the aux belt.

So to add even more confusion the Ford Focus ST170 comes with a 170PS 2.0-litre Duratec ST engine as standard, but that has a cambelt. I know why it does, do you???

>>I know why it doesdo you???

I assume you mean because it is a development of the 1.6, 1.8, 2.0 Zetec engine first launched in the Escort / Orion in '92 and used in the Mondeo MkI and MkII and in the Focus MkI in 1.8 and 2.0 form only, the 1.6 (and 1.4) in the Focus MkI is the Yamaha designed Zetec SE.

Here's the answer quoted from 'zetecinside.com':
"Although the engine fitted to the Focus ST170 has Duratec emblazoned on the cam cover, it isn't one at all. Fords marketing department presumably decreed that their top-of-the-line performance variant couldn't have an engine of older design than the cooker models, and so they dressed up a Zetec to look like the engine that replaced it. The Duratec is an all alloy engine with chain-driven cams and the induction and exhaust on opposite sides of the head. The ST170 engine is basically a trick Zetec with a stronger bottom end and variable inlet cam timing."

Inlet-by-the-bumper = Duratec.

It is a bit confusing however:
If it is chain driven it is the Mazda engineered Duratec unit which dates from around the year 2000.
The 1.25 and 1.4 from the current Fiesta are belt driven which are badged Duratec simply to confuse people however these are NOT they are actually Zetec-S units which date from 1995.
The 1.6, 1.8 and 2.0 Zetec-E units that date from 1991 have little in common with the Duratec units and are belt driven. To conclude:
Zetec-S belt driven all alloy engine
Zetec-E Alloy head, iron block belt driven
Duratec all alloy Mazda designed economy engine, chain driven

I hear that the ST170 engine has a wierd and not very reliable variable valve timing arrangement - apparently its of US design and not very good - according to the Ford mechanics I spoke to...

Duratec all alloy Mazda designed economy engine chain driven
Economy? Economical or cheap to make, if you mean the latter then it would not have had a chain cam.
The 1.25 and 1.4 are still leading edge despite being 12 years old, likewise the 1.6.
The ST170 VVT system is unrealted to the 1.7 Puma.

Hello again.
What about the KA engines as we cannot find anything about cam belts in the handbook.
Sorry for being a parrot and repeating. I will go and get my crackers sqwawk

Both! The Mazda designed and made unit is a fine unit when new; however there are concerns that durability is an issue. I am aware of two engine failures both with the 2.0 litre version. I understand that many people will claim they are the perfect engine and run to over 1 million miles etc. It is a fact that they have been more engine failures with this unit than the legacy Zetec-E. Ford is struggling to keep costs under control and this engine is more for their benefit and accountancy balance sheets than for the customers benefit. Yes chain driven units may be more expensive to make but this engine especially in 2.3 form has had a high number of failures. The 2.3 has been available in the US for many years.
I agree about the 1995 1.25 and 1.4 units being high quality and tractable units. The 1.4 in 90bhp specification does however sometimes burn out its valves by 70-80k. The 1.4 75bhp version would be a more durable selection.
