I have offered to change the timing belt on a friends car, unfortunately, it is a cougar. I do not want to subscribe to this forum for this reason.

I need a guide to changing the timing belt on a 2.0 L Zetec, can anyone assist me please.
 
The crank shaft allways turns in the direction the engine rotates or else it would come undone.!

Is it just me or is this a contradiction? The crankshaft bolt holds the crankshaft pulley to the crankshaft, not the alternater pulley. :oops:

You are correct. I'm not a mechanic by trade and was just guessing the name of it.

Thank you for all the assistance.

I managed to complete the job, with a few issues here and there. I bought a 2nd engine, which I used to replace the pistons and head. I replaced the bearings etc with new, but forgot to replace the piston rings like an idiot, but It runs fine, so I'm not fussed.

I did not need to buy any specialist tools for this job, the only specialist thing I needed was something to lever the crank shaft bolt out against, ie hold the crank shaft while I turn the bolt, which I had a chunk of metal with holes in, loosely attached to the pulley wheel, very crude method but it worked. You'd probably think it is an even cruder bodge if you could see this device I used.

As far as the specialist tool required to align the cams up, I did not need to buy this, I used a straight bit of 5mm bar (old piece of bed frame!), which I wedged into the cam slots when they were in the correct position.

One issue that is bugging me, is that the timing belt is too tight. There is a spare wheel bearing, just above the crank shaft sprocket, with this, it's very tight, without this, it's still too tight. I have left this out and the timing adjuster is still about 1cm past the mark where it needs to be, so I have just left it as is.

The car now actually runs smoother than before!

You sure you got the right belt for the job? There's two types (silvertop and blacktop) plus two different variations of the two if I remember correctly (aircon and non-aircon). If the belt is too tight it'll be more prone to going 'ping' :eek:
 
98/99 switchover: there is one extra pulley on the earlier one iirc, also, the one with the extra pulley is smaller, depending on engine build/number. If the tesion is wrong, and it sounds like it's way out from what you say, that belt won't last very long at all, unless the pulleys give in first ie: too much friction melts them from the bearings.
