Timing belt changed based on age

Thought I'd garner a few opinions on the matter of changing a timing belt based on age. I have a 2008 Kangoo with a 1.6 16v petrol engine. The handbook calls for a timing belt change every 120 000km or 5 years. According to the service receipts I have, the belt was last changed in the autumn of 2019 at about 130 000km. I have no information regarding possible changes prior to that date. It's possible that this was the first time it was changed.

Current mileage is about 170 000km i.e. the car has only done 40 000km since the last change but obviously according to the handbook I should be changing the belt as a result of age, not mileage. It just seems a little strange to change a belt that has done only a third of it's rated mileage just because five years have passed.

The other thing I find interesting is how different manufacturers can offer so wildly different change intervals. It is not the manufacturers themselves that make the belts and I imagine they are all made of fairly similar stuff.

Another reason for posing the question is one of cost. I use the Kangoo as my second car for transporting dogs, going to the tip etc.; It's a general dogsbody car basically. I paid around 20 000SEK for the car and it has cost me very little to run. I do all my own servicing (minimun oil and filter change every year) and in the last five years it has been totally reliable. Unfortunately changing the belt is a faff of a job and I have been quoted nearly 10 000SEK to get it changed (including water pump) by two good independant garages that I trust. This is nearly half what the car is worth! (As an aside I also asked the local main dealer for a price and was quoted the laughable sum of 22 000SEK!)

Anyway enough of my ramblings I have booked the car in at one of the independent garages in January. But I have this nagging sensation that I might be wasting my money.

Opinions?

Well i had a 1.6 vvt break a belt - no warning, at tick over and it totalled head - now my 1.9 dci is 6 years over due a belt, you take your chances but fixing AFTER event is more expensive than preventing it happening, so no not wasting money if you need car daily

Materials within the belts degrade with age, this is why the age limit is put on by makers.
Renault have generally increased limit to 6 years aver the last few years, I believe this is based on statistics of fails that they may be liable for versus longer service life (lower costs for fleet owners)

Pays your money and takes your pick with your belt.

Personally I would be changing it.

9 years and about 70k km here. Did it myself, nearly 6 years ago, but as we've only done about 30k km since I will probably wait a while.
In my book the value of a car isn't what it would sell for, it's what it's worth to me. Our car is going strong after 23 years (15 with us) and it is "worth" almost nothing. We couldn't care less. When something needs replacing we replace it.
I had a belt break 30 years ago and it was a pain, but only bent one valve. Could have been worse.

Belts fail on a bell curve. Some early some late.
Constructors decide on replacement intervals based on how much risk they are prepared to take with their reputation.
Belt rubber goes off with age. Tensioner and idler bearings are not all equal either.
Replacement intervals also have to allow for the fact that some drivers abuse their motors.
So we end up with a Military Medium piece of advice which corresponds to nobody.
If you plan to keep the car for five or six years, do you want to be always wondering if today is the day or just forget about it because it's done? This has nothing to do with the car but what's in your head.
The fact that it has been done does not mean it cannot fail unexpectedly. However, that would be a very rare event and you would have the consolation of knowing that it wasn't your fault through neglect.
It is also a valid strategy to decide that replacement is uneconomical and just drive until it breaks and walk away, no regrets or recriminations. The downside with that plan is that it usually will happen at the worst possible time and place and breakdown recovery etc starts to get close to the belt replacement cost.

How about this for brutal.... bought a family wagon 2012 Grand Scenic a few months ago. Now, as you will gather from this, I am not a mechanic nor am I a mystic. It had just been MOT'd. The brakes squeaked a little, so took it to the garage. The mechanic called me and his first words were 'Who the F**K MOT'd this mate?'. Anyway, various new suspension and brake parts later, a £800 bill (should have been a grand but this garage does non-tax options 😉 and I was skint than skint at the time). Next up was the clutch (dual mast of course) which was a grand (£1200 had I not gone the non-tax route).

ANYWAY... I've had an oil change, filter change, and it is now booked in for the timing belt, auxiliary belt, all tensioners and bits and bobs. The reason is because IF THIS ENGINE BLOWS UP NOW AFTER I'VE SPENT ALL THAT ON IT I WILL GO ON A EFFING RAMPAGE!!!! 😂😂😂😂 It's on 102,000 having never had the belt done, so I'm asking for it! The risk is building!

I'm committed now, so I'm keeping this bad boy as long as humanly possible, and in the best condition I can. No services missed, no job left waiting. Sod it.
