Variator and water pump on cambelt change?

How often do variators fail? This is the variable valve timing unit right? I have to say I've never heard of any failing other than on Alfa's.. who makes them? (badly!)

I'm trying to work out if I should do it when I get the cambelt done. It's easy to say get it done for peace of mind but it's me that has to pay for it (extra 137)

Plus what about the waterpump do they need doing as well - how many people have had one fail does it take the engine out when it fails?

I'm looking at 386 + vat so 450 maybe with a variator but no water pump.

Plus one of my power steering pipes has bust which is 50 for a pipe!! plus 75 labour so it's all going to be 600 minimum probably 700 to allow for any other minor parts/problems along the way

I'm not liking the alfa too much now but at least 25mpg (1.8TS) won't bother me anymore when i'm shelling out 6-700 shortly!

sorry rant over!

Do the diesels have the same problems/fragility?

They are not fragile, they just need looking after!

if the variator has never been changed, then sods law if you don't, it will start to rattle next month. the water pump is not a common failure item on the Twinnie but with zero labour on a cam belt change, I would change it.

have a look here as a guide Alfa Timing Belt Change Special Offer

1.8 ts belt change 230 + 95 inc vat for variator & fiting
Waterpump is 35 inc vat, fitting will not be much either.
Total 360 plus waterpump fitting charge

As mitch said if there's no record of either variator or waterpump being done it's not worth leaving them as the belts have to come of to do them anyway

Since you have the 1.8, at least you don't have to worry about the additional balance belt/tensioner change that the poor old 2.0 owners need to do. So consider yourself reasonably lucky!

Seriously, it's best to shop around for better prices, the rates do vary between specialists. On the variator/waterpump it all depends how old/mileage is on your 156 TS 1.8. If this is the second belt change and your 156 is roughly 6 years old then change both. If the variator rattles later you'll need to take the belt off again to replace it. Waterpumps on the TS are good but they are known to fail on higher mileages, this can break the belt and ping goodbye engine. Again if you need to replace the waterpump later then off must come the belt. So makes sense to replace it, get a coolant flush and replacement done at the same time, you need to replace the coolant every 2 years anyway.

As mitch says, they're great engines, but you need to look after them. Cut corners with these engines at your peril!

Variators don't really fail as such,they just get noisy. You get the diesel sound on start up that lasts longer the more worn the variator is.
