That certainly sounds like they are being on the safe side.

I thought anywhere between 75,000~90,000km was valid.

Although I would say you have to make sure that NOT doing cambelt change will not void your warranty...check your Alfa handbook to see what it says is acceptable intervals.

Dear Zalik
The Alfa service schedule advises checking the timing belt at 60,000km and replacing it if there are any signs of wear (eg. rubber dust) as a maintenance item.

Depending on the climate and other operating conditions- eg. excessive sand and dust this could accelerate wear of the belt and cause premature failure.

The schedule doesn't say to check the belt again until 120,000 km or 3yrs which is a long time at the end of the belts useful life. Although the belt replacement is a difficult and expensive job it is much cheaper than replacing 24 valves, pistons and possibly heads.

If you don't replace the belt at 60,000km I would strongly advise rechecking it regularly- at least every 20,000km thereafter, although it is very hard to tell exactly when a belt is going to fail when it is fitted in the car.

Best Wishes
Damon

Thanks,
I'm sure that they'll change it also if the belt is in good condition but the price for 60000km + belt is about 600US$ !!
But it's cheaper than to rebuilt the engine for sure.

Guys,
Service schedule says check/replace if necessary at 60,000km (30,000mls) and replace at a maximum of 120,000km or 3yrs.

As I said earlier, there is a long time between 60 and 120,000km and if leaving the belt I would check it regularly. Only problem is the labour cost of continually checking the belt and it is difficult to tell condition when inspecting in the car.

If the belt breaks beyond 60,000km after replacement was advised any consequent damage may not be covered under warranty as the belt is a "maintenance item"

Personally I would not leave the belt longer than 100,000km (60,000mls) at the absolute maximum. I have seen some belts dangerously worn at this mileage.

If you change it at 100,000km+ I would suggest you change the tensioner as well as they can tend to get noisy and if it fails later you could end up doing the whole job again to replace the tensioner.

60,000 kms in cold countries because of cracking. This was a Swedish directive.

... iF you can do change it. Imagine driving your car aftre 60.000km and everytime you might think of it, you will straight away think: should I have changed it? is it going to snap now? better be secure with these things. In the old days it used to be 100.000km but with newer models it's 60.000km. Fiat is also having the same policy.

I was told it would need to be changed at the 72k miles service (and it was). Should this have been done sooner then, and should I be planning on having it done 60k miles later or not? Mine's an S98 model.

Re: 156 V6 Timing belt change interval

My belt was changed at 58000 miles, when should I change it again?
It is on 92000 now is time as important/ critical as mileage?

Re: 156 V6 Timing belt change interval

There seems to be some crazy advice going around.

1) Alfa still claim that 72,000 miles is the recommended interval (roughly 100,000km). This recommendation is totally discredited from information gleaned over many years on the 164 Digest forum, the AROC forum, AO, and everywhere else.

2)There are TOO MANY cam belt failures on the 24valve engine at or around the 60,000 mile mark. Not every engine fails by a long shot, but I have personally spoke to owners whose engines have self destructed at 58,000miles and 61,000 miles, and my own 24valve had such a failure. The forums have many more instances and its too many to ignore.

3) To be on the safe side my personal advice would be not to let a 24valve cam belt go over 50,000 miles or about 70,000km.

Its up to each owner to choose of course, but remember your car becomes virtually worthless if the engine lunches itself, and you are then faced with a depressingly large bill if you choose to have it fixed.
The cam belt replacement bill is quite big enough, but its the preferable of the two.

Re: 156 V6 Timing belt change interval

I guess that helps, common sense says err in the side of caution, and I'll be changing mine at about 105000 then.
thanks for the advice, Ill be back!!!!!

Hi, a bit old this thread, by the way...to be safe its a good idea to replace the timing belt every 45,000-50,000 miles, but how many years? Im seeing a 156 V6 for sale, the timing was replaced 15,000 miles and 6 years ago. The car is 300 miles from home do I would have to drive back that distance.

Thanks!

The officially advised interval on V6 engines is 72,000miles or 5 years - whichever is sooner.

unless the engine has been standing for ages you should be fine to drive the 300 miles home and use the car for a bit.
You can loosen the belt cover and make sure the belt is running nicely on the cam pulleys and not sliding off towards the covers which can happen if the tensioner starts to disintegrate.

15000 miles isn't much, so the belt should be fine for now, unless it has been left standing for yonks.
However, if it was me I would get the belt changed soon. And if there is no history with the car, then also all the timing belt roller bearings. These can seem beefy and strong, but they do fail. Then also, the water pump, and also the auxillery belt, tensioner and pulleys. And, make sure the aux crankshaft pulley is still running straight. In Britain at least, the salt water can get in the seal, and rust causes the pulley to go out of shape.

I have just had all this work done on my 166 3.0. I have the full service history for the car. It has done 164,000 miles on the original aux belt tensioner and bearings...(they were shot, as was the crank pulley). The camshafts are still as new though.

Also, these engines can suffer from belts done on the quick (I.e only locking the front two camshafts, leaving stripped threads in the block (waterpump or rocker covers) , re-using rocker cover gaskets again and again, only changing front bank spark plugs etc...) .

It is one of those things, I would use the car for a while, (as long as the belt looks good from a visual and audible check) and if you decide after a few months you love it and will keep it, then get everything done properly. There will be other issues to sort too...anything from clutches to suspension arms/antiroll bar bushes...though in Spain, maybe not rust?

When I bought my car it had done less than 20k on the belt and was done 7 years previously. The belt and rollers were still in great condition so I left it untill the summer to do it with no issues.

V6 belts don't tend to snap - the pulleys go squiff and they rub, until there is no belt left. Then they snap. TS belts just snap - they're much weaker.

The simple check is this:

- remove 2 of the bolts holding the cover on (LHS of the engine, one is roughly in the middle, the other is on the RHS) 10mm bolts.

- pull back the cover and look at the pulleys

- what you should see is the belt sitting on the pulleys and about 3 mm of rusty pulley surface exposed

- if you see shiny pulley surface exposed, the belt is wandering. Do not drive car, go straight to "change belt".

- shine a torch down into the void - if it is all nice and clean, you're good. If it is full of little bits of chewed up rubber ... do not drive the car.

My GT is coming up on a 5 year belt anniversary - but only 10K miles. I check it about once every 1000 miles (twice a year). Will probably run it to next year, then change it.
