Edit: and yes, 7 year old coolant is a bad idea - the antifreeze, lubricant and anti-corrosion properties will have largely disappeared.

Edit #2: I do hope the sump oil isn't 7 years old too...

She's booked in!

Am going to change Cambelt along with tensioner and idler in kit.

also the balance belt and cog.

Coolant- may do that on another visit, is it worth getting it checked for its properties or is 7 years (4.5 not used) going to be pretty much an idea to change anyway?

Sump oil- why you cheeky!!...
Yes yes don't worry. Apart from that the oil seems to be drank/ burned up over time I have the oil and filter changed yearly.

Last time I used Petronas Synthium along with a K&N oil filter which works a treat....

Mighty-147: do yourself a favour and get a new water pump NOW as well .. this is driven off the cam belt and if it does start to leak (which it eventually will, my first one lasted about 100k miles and the bearing seal went .. ) it's a new belt change again. Then you can change the coolant and you can stop worrying for a bit!

Yes, replace the coolant.

If it is pink, it is good for 5 years, if it is green it is good for 3. You are way over the time limit for both. As Gazza says, do the water pump while you are at it.

The belts, pulleys and tensioners, variator, water-pump and coolant were all changed April 2009.
Car was sat idle for 4.5 years but turned over periodically in between that time.
Has done approx 11K since.
(see start of thread/ original post)

The coolant level has not moved at all in that time and I have never had to top it up.

The coolant is bright red and I just got back from my local ATS where I have my recent MOTs done and he assured me it's fine.
(I'm having my cambelt to be done by an Alfa indie not ATS don't panic)

I reckon with that low milage on the coolant and also the water-pump it should be fine.

yes whilst they are there I could get the water-pump changed and the coolant; but I havent got that much in funds at the moment and is it really really necessary?

I reckon just the cambelt and balance belt with tensioners etc.

I can do the waterpump and coolant next belt change....

The coolant's anti corrosion additive is broken down in about 2 year.
The water pump is 29,50 Cooling for Alfa Romeo 147. No extra labour cost involved. False economy not to have these things changed while the mechanic is at it.
The cam belt change was reduced to 3 years and 50k miles - what ever came first - very shortly after the lance of the 156.

*URGENT*

The three year limit on the age of the Cam-belt/ Timing-belt;

Is it specifically the date three years from when the new belt is fitted,
or does the actual age of the product manufacture bear any significance?

Within reason of course.

The date of packaging on the box for the Cam-belt is 20/05/2015.

Have I already lost over a year of quality it being 1 Year, 2 Months and 3 Days old
(and the date of manufacture of the belt stamped on it inside may be older than the date of packaging)

or is it purely 3 years from when the belt is actually installed?

Thanks!

I need reassurance!!!

Or on an old car that's rapidly approaching scrap value you can just drive around till it snaps. Do you feel lucky?

If the packing date is more than 1 year installing I wouldn't accept the belt kit.
But I don't think it will deteriorate in the first 2-3 years if kept in a ware house or similar.

If the belt had a shelf-life it would be on the box .. from installation. It's more the flexing under tension that is the issue, plus it is in a harsher environment that a warehouse shelf.

Get the mechanic to double-check the belt though for cracking caused by poor storage conditions.

They do know how to line up the balance belt? It's not a case of simply sticking it on!
