undo lower cover
undo bottom pulley
release cambelt tension
remove idlers
lock pulleys

remove dephaser
assembly is the reversal of removal.

With the greatest respect chaps I didn't ask if I should do it myself, I asked if there are other guides on the forum.But thanks for your concerns
One thing to mention, you will need all 3 tools to do the job. Some people think they can get away with just one, which is where it goes wrong!

I found that link - really usefull!
I have all the tools but was looking for a better explanation of how to go about it.

Only on CS.
The Renault pdf says you can use just one unless you have a need to undo the cam pulleys i.e. dephaser or cam change.
Lol really. If your an incompetent fool like most of CS I suppose you might be right
I'm only going from what others have said countless times, it seems to be a common thing so assuming they read the instructions properly they'll have no issue
I didn't say don't do it, I was explaining why there are probably no 'step-by-step' guides
If you want the service manual, I can pm you that over, but its not a 'step-by-step' guide.
bit of a twatish comment that really don't you think? Most of Cs aren't mechanics or only dabble in it now an then. The timing on the f4r is very easy to get wrong, even garages have managed to do it wrong countless times.

Which you will have to do to get it right
I disagree Mick.
Renault say you can just undo one.
I've done it both ways many times and got the timing right without issue both ways.
I've also know a guy who used to work at the Renault dealership who said they only undo the crank pulley for a simple cambelt change.

Because when i do them Mark i always change the camshaft oil seals as the dephaser is the common one for leaking. Yeah you "can" do the belt change with just the exhaust spinning (providing the crank sprocket is also spinning freely) but you've got to lock the pulley to remove loosen it and it takes no extra time to do the same on the inlet side why wouldn't you?
Do you check dephasers for signs or movement or leaking from the oil seal? My warranty is my pocket so I like to ensure I am covered by checking and replacing everything.

That all sounds sensible, you didn't mention any of it in your previous post.
with all due respect, I wouldn't pay any attention to anyone advising not to use all the locking tools. It's bad advice, anf anyone handing out bad advice, shouldn't give any advice at all.

I didn't because I wasn't trying to tell people how to do the job. The manual is out there for people to download which allows them to give it a go but if they don't fully understand it they're gambling a lot. I wasn't having a go at anyone either Mark... i'm all for DIY'ing but I hate it when people say I (as a trader) scare monger on CS when I clearly don't.
Mick
I don't think you or any other trader on here scare monger and I'd happily recommend you. As you say it is different for a DIYer.

Question about setting the tensioner guys,
How do you know if you have it right?
I ashume that when you set it so that the marks line up and then rotate the pulleys you shouldn't get any movement and the marks should stay aligned?
When you torque the pulleys onto the cam and turn the engine over you will see the tensioner moving as it adjusts the belt tension depending on the action of the valve train?

Yes essentially mate, it will change when turning over the engine by hand but it should settle back to the marks or very close to it. The Allen key hole on the tensioner should point at circa 12 o'clock and not be past the centre stud between the inlet and exhaust cam pulleys iirc.
Fred had bother with tensioners running out of travel and it causes a potential clicking/knocking. Anything more than stated and the heads probably been skimmed and your needing a larger tensioner to take the slack.
This is wrong, was on one of my Clio's when I got it.

^^^^^Holy s**t! Flol! Yeah that's definitely wrong!!

Ive just been quoted £600 for both belts and the dephaser pulley (which i definatly need replacing aswell) ...does this sound a decent price?
Seems like a nice price, if you are close to DTM Performance they have a special offer of £525, but only 1 more change at that price.

I'd go to a specialist anyway, I know it's said all the time, bla bla bla, but it's said for a reason xD
Its pretty awkward to do, and its easy to get the timing slightly wrong and lose a small amount of power, so having ALL the correct tools helps lower that risk, but if you are really careful and you make sure you check it back afterwards by pinning the crank after you have spun it over a few times you will know if its right or not and can then just keep having another go until it is if you are trying to get by without all the tools.
It gets easier every time you do it, if you watch Mike from MWM or Dan from SJM (and presumably Mick at diamond, danny @ 519, or fred too but Ive not seen them do it) then it really does look simple, but when you first do one its quite fiddly, I still dont like doing them if the engine is in the car just cause its awkward when you arent used to it, but on a stand its a piece of cake and thats how I normally do them (as I tend to be building an uprated engine not maintaining a standard car as im not really into that)

the pdf is wrong, if you read the french version is states that engines WITH VVT must have the pullies undone to replace the belt, and non vvt engines you don't need to touch the pullies
on the uk pdf it shows a picture of a not vvt engine but with a vvt description (or vice versa, i forget), ie its totally wrong, hence why there are a lot of f**k ups
pullies MUST be undone when replacing just the belt - the end

Yeah this is a renault specialist in Doncaster - they did my first belt change.
But if there is no play in the dephaser why would it make a difference whether it was on a VVT or not?
Do you have a link to the French version?
You've not exactly a small man Chip.
Hands like shovels doesn't help.
Lol, indeed, some jobs like changing bulbs for example I just leave to the mrs as her hands are tiny by comparison.
