Renualt Trafic II 1.9cdi Cambelt Change

2003 Renault Trafic cambelt, water pump and tensioner change.
Showing timing marks, step by step.
Doing this at home with only hand tools. (January. 7ºc, outside)
I have many years of experience as a mechanic but it was the first time working on a Renault Trafic.
I have since spoken to another Tech and I believe the Fuel Pump is what is known as a High-Pressure Ev Pump, which in theory means that the position on the pump pully is not important as the pump just feeds the injectors that are electronically controlled. (test at your own risk)
The belt on this model comes with timing marks that line up with the cam and the crank. No marks for the Fuel pump. Other models and makes may be different.
Thanks for reading and watching.

Thanks for this. No nonsense. Exactly what I need for brother in-law's 200,000 mile Trafic II!

The high pressure fuel pump of a common rail diesel is only supplying high pressure fuel, it is not controlling timing in any way, therefore that is why there are no timing marks for the high pressure fuel pump. Engine timing is provided by the crank position sensor and various other parameter inputs from numerous sensors and is controlled by the ECU powering the injectors on and off.

Brilliant, thank you David, very helpful. 👍

I have this to do on a van next week, i'm changing the radiator too, so will be taking the front of for that, and I'm not that tall, so it will make it a bit easier to get to the rest of it. Also, I have the timing pin, so hopefully should get it spot on. You forgot to mention how you have to tension the belt using harmonics, and twang it to get it to 88-90Hz tension, before tightening the locking nut on the tensioner. I use Carltune app on my phone to do this.

Cracking video. Lots of info 👍

Thanks for the comment, pleased it was useful :)

Am doing this myself, I done my old LDV Convoy, but this looks very much harder! Basically put crank and cam locking pins in and also mark everything to make certain, yes? Many thanks!

Great Vid , I doing the same work to my van without the removal of the front and rad, cant get to the crank key hole (limited axcess) if I remove the belt without the key in would this be ok?

[@caspar1975able]

I think, I may have cover this in your other message?

Hi ,good video lots of info, I have the same van an I’m having fuel pump problems is this the same process to get the pump off

[@caspar1975able]

Hi, yes, and a new cambelt at the same time as removing a pump is a good idea.

[@matuskinas1]

after my van 1.9dci 2006 timing belt snap, i looking exactly how should be timing adjusted, and this info is nothink very hard to understand

[@caspar1975able]

Thank you for the comment. Yes it is a simple engine to work on. I hope you got yours fixed.

[@garyharvey7905]

Did you use a timing pin when you removed the belt?

[@caspar1975able]

Hi Gary, no I didn't use the pin, just carefully removed belt and marked as best I could. I find a lot of these pin crank holders hard to fit as the blank holes aren't easy to get to

@@caspar1975able thanks for the update. Yep I've took it all apart, parts arriving Monday 🤞 great information. Cheers
