i have a 2.5 v6 zetec s estate mondeo on a 52plate its called a zetec but has duratec engien are these the same things as i would think it would be a zetec engien like the mk1 and mk2

Ford changed the meaning of zetec from an engine name to a spec of interior etc

If it says Duratec it will be a Duratec.

ah right ok thanks for that just wasnt sure aint had a ford for a while thanks for the reply

No problem

Ford had the name Zetec for the engines in the Escort's etc, but when the Focus came on the scene they changed the meaning of the word Zetec from an engine name to a car spec, just like Titanium is too

First we had the silver top zetec engines then the black tops now duratec.The MK1 focus RS has a zetec even though its called a duratec.

No

The zetec and duratec are different engines. The duratec is all alloy and has a timing chain, better gas flow through the head and is a more powerful and torquey engine than the zetec. The zetec is belt driven and has an iron block.
Mazda were the developers of the duratec engine at the start too

Doesn't sound quite right. The range of Duratec's in the Focus are cambelt driven. I know the Mk 3 Mondeo Duratec engines were chain driven, therefore for a period, what you are saying was correct.

I stand corrected then lol

Cheers for the more accurate information

The Zetec engine is cam belt driven, the Duratec chain driven.
Ford changed the name ( re badged) the Zetec engine in the Focus to Duratec i.e. The ST170 engine is a Black top Zetec badged as Duratec.
The difference between the Zetec and the Duratec that is easy to spot is, looking at the front of the engine, not the gearbox end, the zetec has the inlet on the left, exhaust on the right, Duratec inlet on the right, exhaust, left.

So the Duratec that is a Duratec is chain driven and the Duratec thats really a Zetec is belt driven. LOL

So my 1.4 duratec is a duratec even tho it says ecotec se under the air.cleaner/filter? Lol
