Alfa 156 2.4jtd service advice

[mike9009]

Hi

Our 156 2.4jtd, is coming up for three years ownership. We had the belts ( not water pump) changed when first bought at about 68,000 miles. Now three years later and at 92000 miles should we change again and potentially change the waterpump?

Prefer not to have potential 'big' service bills. Is it only the 2.0 TS engine that needs regular attention or is it worthwhile on the 2.4jtd.

Incidently, i won't be sueing anyone if they recommend not to. Just how often do belts and water pumps fail on these engines?

Hi Mike.. take a look at this from Alfa Workshop - service schedules....

http://www.alfaworkshop.co.uk/alfa_romeo_servicing...

Apparently Alfa say its every 5 years/72K on the diesel, but AW recommend a shorter timescale.

If your belts were done say 3yrs ago, you could maybe go another year..but if you did not do the water pump maybe a good idea to at least to do this. But its like everything, if you're taking that item out may as well do the belt whilst you are there. (afterall, water pump tends to go hand in hand with belt change outs) Bit of a poser???

Incidently, mate of mine has the 1.9JTD GT and has only just done the 1st lot of belts/water pump change and service at 4yrs old and 45,000 miles. On my 2.0TS, the first belt change was done at 4yrs/40K miles and then at 7yrs/71K. The water pump was changed on both occassions as for the sake of £40 quid part worth getting it swapped out.

Obviously prevention and precaution is cheaper than cure (if it went bang!)...just comes down to you attitude towards risk I guess??

Change the pump! They seize and cause the cam belt to fail.

You were wasting your money. the T/S pumps are generally reliable. I'[d change them at 100k as a precaution but not at 40k and then again at 70k...

Hi Zombie,

Any experiences with your fleet with the 2.4 JTD? Is the waterpump really that unreliable compared to the 2.0TS. I may risk waiting another year before changing both. We are doing slightly less mileage in the Alfa now.

What does Cam belt failure mean on these engines? Is there any interference of components in the engine?

Thanks for any advice .... I will probably regret this and be posting in a couple of weeks that somethings gone pop!

Ive never had a waterpump fail except this year on my Eunos - luckily no internal damage.....

Water pumps are only a problem on the multivalve engines afaik.

Which engine is in the 156...?

I agree if you have a multiple valve diesel change the pump and belts have a read through this

Mine failed on my 1.9 jtd multijet at 56kv - needed a top end rebuild £1800

remind me, is it also the case with these that some water pumps have plastic impellers and can be upgraded to metal ones, if not, which alfa is it then?

Hi Wrinx - mine is a 2001, 2.4JTD which I believe is the 10 valve version. I think this changed in 2003 to the 20 valve.

So based on this information, mine should be okay for another 12 months or so?

The 10v's are more reliable yes but they do fail judging by what I've read. (I don't have much experience with the 10v's...)

I'd replace it but you may well get away with it.
