Timing belt tension

[skyship007]

If you want to be a long term owner, do not listen to how anyone else except Mr Volvo does a main cam belt service. Some clowns only change the cam belt and in most cases when the cam belt has broken, it's the tensioner, aux belt or water pump that failed.

Pay particular attention to any torque settings, as it can result in some real trouble with water pumps and tensioners in particular.
If the water pump is a non OEM one (It will say Renault on the inside), or shows any signs of side or end float, it should be replaced and a new gasket is required.

If there are any signs of a cam shaft oil seal leak, it should be changed. If the car has be washed underneath on a regular basis, it can be difficult to see if it's leaking until the cover is off. The V40 diesels are not known for oil seal failures, but it's still good to check.
The pulley only needs removing to change the seal, which obviously complicates the timing situation.

I don't think that any of the bolts need locktight, but if they do (The EGR ones do), don;t think that just because you think it feels like it won't come loose, that you can ignore the instructions, or use the wrong type of thread locker.
Lower strength thread lockers are sometimes used to stop a hex bolt or machine screw corroding in and that can make the next change a real PITA.

So had my timing belt tensioner and cam sprocket replace and now my check engine light is coming on my question is how hard is it to get the car back on the right timing taking it back to the shop that did the work they used the tools required to change a timing belt also had seals replaced and the cvvt was slinging oil so it was replaced any advice would be appreciated

Ps I did read somewhere that the tensioner could be to tight causing the cel to com on

Yes, but I don't really enjoy working on engines anymore and prefer to pay others that have the correct tools and software. I also like the 2 to 4 year warranty that you get when a job is done by a good Indy.
If you fit expensive parts yourself and they fail, it's very difficult to get your money back and compensation for the damage done by their failure, or the waste of time involved.
Very few non farmers do their own maintenance in Germany because of the regulations concerning fluid disposal (You can't even wash a car on private property) and what you are allowed to do on private property. It often prohibits vehicle maintenance in the land rights or property lease terms.

There are some classic car clubs that have real good tool kits and ramps or lifts, but none in my immediate area.

Germany sounds like a dictatorship skyship.

Not heard of a tensioner fitting fault causing a check engine light before, BUT if the timing is off, it can trigger a CEL although I'm not sure what the limit is, as it might be 2 teeth off rather than one. 3 teeth off and it might be new engine time!

What was the engine doing when you ran it ?

One of the forum guides does cover resetting the timing after removing the pulley.

I've got some references to it in my VVT guide. See my footer for links.

Thank you great stuff, I would also like to know, if I may, do you know if the vvt solenoid goes out will it distroy the vvt plunger o ring? Worried that the new vvt I had put on my Volvo may be in jeopardy if the solenoid that was put on isn't working properly the car does go in Friday to find out why the cel is on
