Laguna 2.2 DCi cambelt change

[Pupp]

Reasonable home prospect or dealer only? Thinking clearance and special tools needed etc

Could do it yourself but buy the locking tool laser list it and costs about £60 which is a lot less than you will pay for labour. Be prepared though its not much fun to do and probably worth getting some form of instuction (Autodata etc) which will give you any special instructions torque settings etc. Try the local Renault dealer for the belt kit as they tend to be cheaper than aftermarket and our local one will lend you the locking tools to do the job for a reasonable £10!

Thanks, that's helpful... what's the need for the locking tool? Is it 'just' an aide to keeping everything still for timing purposes or is there something peculiar about the motor that means making marks and counting teeth is not a viable strategy?

It has floating pullys ie there are no woodruff keys on the crank or cam (the pullys are held in place by the bolts) which means without the tools it makes it nigh on impossible to time the engine correctly.

Is this perchance the same design of Renault engine that is in the Vauxhall Vivara 1.9tdi van ?

I'm intending to do a cam belt change on one and can't seem to find a way to lock the front crankshaft pulley.

If there's special tools involved and a fair chance of fubarring the whole thing up I'll suggest my mate takes his van to a dealer/ specialist to sort it out.

While I'm here is there a foolproof way of bleeding the fuel system as there's still air in the filter housing from when we changed the fuel filter and its getting tedious pumping the rubber bulb to help the buggar start.

Cheers,

Tony

its a similar design but not the same its easy to lock the crank with the correct pin it goes into the block at the front at the flywheel end just above the sump line you will find a bolt which is just a plug undo it screw pin in then turn engine over (by hand) till it hits pin and its timed.

If you have to keep pumping the air out its getting in somewhere, id first check the seals on the fuel pump you have changed.
