Mk5 Fiesta 1.25 Zetec Cam Belt + Coil Pack + Engine Warning Light

05 February 2009 - 11:44 PM

Hello, I'm new to the Ford fam, having blown up a few dodgy Rovers over last few years :rolleyes:

Y Reg 2001 Mk5 Fiesta 1.25 Zetec Petrol 57,000 miles

Engine warning light came on last week, running rough, shaking, miss-firing. Checked plugs, (wrong type, NGK PTR5A-10, but ok). Found one HT lead badly corded at end that joins coil pack, which itself was corded and full of crap in same terminal.

Replaced plugs with NGK TR5A-10. Replaced single knackered HT lead. Replaced Coil Pack. Firing on all 4 again :)

Q1. The Haynes manuel said the spark gap needed to be 1.3mm, but I read on Interweb that Ford originally set it to 1.3mm and found HT leads dying early, so changed it to 1.0mm. So is it 1.3mm or 1.0? I went with 1.2mm, hope this is ok / reasonable compromise.

Q2. The engine management light is still on, but the car is running ok now. Best option to take to dealer to have laptop trickery?

Q3. The timing belt, subject of billions of internet posts :) I keep reading that its 10yrs or 100k miles, however the Ford Warrenty and Service Manual says:
"Camshaft drive belt, tensioner and idler
Renew Zetec, Zetec-E (without auto-tensioner) every 5 years or 80,000 miles"

next page
"Camshaft drive belt
Renew Zetec E (with auo-tensioner), Zetec SE Endura-DI every 10 years or 100,000 miles"

The Haynes manual says "Every 40,000 miles for Zetec SE"

3a. Apologies for being thick, but I'm not sure which of the above applies.

3b. There is a chance that it's already been replaced. Looking back through the history I found an Invoice for:
09-SEP-04
25,108 miles
Belt 20.56
Gasket 6.45
Seal 4.25
Tensioner 27.19
Water Pump 66.92
Plug 49p
Bolt 1.55
127.41 Labour 375

Unfortunately, it doesn't say what the belt was, but seeing the water pump and tensioner, having read many posts, I believe these tend to get done at the same time as the cam belt.
However, I realise that these are pretty big assumptions, it could be the Alternator Belt. And given the 25k miles, it could all be garbage and the garage just ripped the previous owner.
I guess there might be a sticker possibly, but I didn't see one.

3c. In short, I guess I should get the cam belt done in 2010 to be on safe side (do a lot of short, sub 5 mile, often stop start journeys). I had the alternator belt done in Jan '07 and possibly the tensioner was done in 2004, but should these all be done again at the same time?

Apologies for the long first post, many thanks for reading it! :)
My first Ford, and although I found doing basics in cramped engine bay tricky, the usability of the cockpit is great. Going from a 20yr old car to this, you can really see that a lot of thought / design has gone into making it a nice place to be.
I also REALLY like having a small car, it corners like its on rails compared to previous boats. Although 1.25 is, well, 1.25.

Many thanks for any pointers / help / tips etc (I'll keep future posts shorter, promise).
