V40 Cam Belt Replacement
I previously owned a 2.0 litre petrol V40 on which I changed the cam belt twice using the instructions and specifications in the Haynes manual.
I now have a 04 diesel (115bhp) V40, unfortunately the Haynes manual does not cover this engine. Where can I find instructions and specifications covering the cam belt replacement on this diesel engine? I understand this 1870cc diesel engine is in fact a Renault engine. Maybe a Haynes manual covering a Renault would give me the information. Which Renault models used this engine and would the replacement intructions & specifications be broadly similar? Thanks, TC |

Thanks Paul, that's helpful, not entirely dissimilar to the 2 litre petrol engine, perhaps not surprisingly. I wonder, can it really be done in 2 hours, it took me the best part of a day to do the petrol engine. Is there a suitable alternative to the Volvo tool 951.2797 for tensioning the belt?

Belt
yes 2 hours is about right, i have done them in about an hour but that is in a properly equiped workshop (two post ramp etc).
you do not really need a tensioning tool if you have changed a petrol one before just make sure it is about the same tension perhaps just a tad tighter being a diesel. Paul.

Thanks again Paul. You must have about a dozen arms if you can change one of these cam belts in 2 hrs or even less, even in a properly equipped workshop! I guess this is the difference between a professional (which I assume you are) and an amateur (which I am).
As to the cam belt tension, the two I changed were on my 1996 2.0 V40 which has an automatic tensioner so tensioning it was not an issue. However I notice that myvolvoshop.com have a tensioner for this engine (see http://www.myvolvoshop.com/Engine-Ti...uct_info.html?) for £35, probably plus p&P & vat. If it really does the job, and I'll make further enquiries before purchasing it, it may be worth the investment. I don't feel comfortable about using the "you should be able to turn it about 90°" for such a critical component. Incidentaly, is 85Hz the format for measuring belt tension (the figure given in the Autodata specifications), I'm more familiar with x mms deflection under y kgs pressure? TC |

Thanks to Paul for the pdf files. I have just taken the plunge and started to change the belt on my '02 S40D (115bhp). So far, so good (it went dark on me!). The crank pulley came off easily and an 8mm drill bit is locking the crank nicely - although I had to remove much of the intercooler piping to reach the timing plug (11mm).
The 85hz is a resonant frequency which changes with belt tension (allegedly). Sealy do a tension meter and the sp is to 'pluck' the belt between finger and thumb. The meter then records the belt resonance. Fine - if you can get a finger behind the belt in the first place! Also, the meter is over £400, so it is back to bodgit methods for me. I have been changing belts for 20+ years on my 240s, Transits etc., using nothing more than a hammer and screwdiver, plus some common sense; are newer engines/belts really that much more critical? I tend to 'take up the slack' (just taut) plus a bit. If I can twist the belt more than 20-25 degrees using moderate finger pressure, it is too loose. Does anyone know of a more 'precise' rule of thumb? I'm planning to fit a new tensioner, but leave the water pump (at 57k miles). Is there anything else I should be looking out for? The alternator pulley sounds fine - as far as I can tell, but I will fit a new poly belt. Bill |

Cam belt is on, poly belt fitted and nothing has gone 'bang' so far (tightly gripping a large chunk of oak, specially kept for the purpose of superstition).
One possible 'rule of thumb' for belt tension might be the force needed to rotate the tensioner pulley by hand. Could someone try this on a (properly) tensioned belt and report back please? It takes two finger and two thumbs to turn my tensioner pulley now, against the tension/friction of the back of the belt. This after turning the cam sprocket back a fraction to release pressure from valve springs etc. Anyone planning to change an S40D cambelt, particularly on a pre-2000 car, should take a look at http://www.gates.com/europe/ Click on tech bulletins and select bulletin #17. If you want to feel lucky, take a look at bulletin #19 (same engine for Renault) - there are about ten different belts! Bill |
