1.6 Zetec focus 2010

Recommended Posts

Unable to find any evidence of cam belt change on my focus, and at now nine years old it needs doing. Am I right in believing that this engine is non interference, and should not suffer catastrophic damage if the belt broke..  I fully intend to bite the bullet and have it changed..  I was confident of it being a non interference engine till I did a google search, always a mistake, so much misinformation out there and much of it mischievous.

I thought it was an interference engine (ie. valves will hit pistons). I thought non-interference engines disappeared years ago due to the engine designers making the engines more powerful and economical.  But I admit I can not say with 100% certainty on your engine.

Correct, they just can't achieve the efficiency we need for low emissions nowadays without being interference.  The Focus 1.6 (both petrol and diesel as you didn't state which!) are interference engine so I wouldn't recommend risking the belt.
