Just picked up Mondeo from dealers. Turns out the aux belt tensioner=20 pulley wasn't the problem but the alternator was.



Anyway, they fitted a new one - total bill =A3210 - without telling me=20 first.



=A3210 is a lot of fooking money for an alternator, even with main dealer= =20 labour so I do a bit of ringing around.



Well my favourite reconditioners won't even touch them as they're such=20 a bastard to do so that kind of got me a bit worried. Phones a few=20 factors to be told it'll be between =A3140 and =A3170 depending on which=20 one of 4 it is that's fitted to my car.



So..potters off to the main dealers and gets the bill. =A3114+VAT for a=20 brand new genuine Ford alternator. F*CK ME, THAT'S CHEAP. 1.5hrs labour=20 for investigation and fitting.



Turns out I got quite a good deal. Bit of a heart attack with the=20 labour but you need a special tool to relieve the aux belt tensioner in=20 the first place (could do it with a 1/2" ratchet but the engine is too=20 close to the inner wing to get it in) and it's still a good hours job=20 just to change the belt.



Explained to the woman who had rung me that I'm used to =A350 for a Capri= =20 alternator and it being 10 minutes to swap it over - 5 of that spent=20 putting the kettle on for a brew when the job is done, so it came as a=20 bit of a shock.

My Focus 2.0 TDCi alternator failed a week out of the 3 year warranty. I get on quite well with the tech at my main dealer and he managed to get Ford to pay 40% as a goodwill gesture. Still cost me £220 which I didn't think was too bad.

I bought a DS alternator last year ... 150 quid.

I sincerely hope I don't need one anytime soon.

That's a cheap one!

That's for the older 4.0 diesel... not many made...

What's the rating on those? 1.21GW?!?

they are, but thankfully it's illegal to do 88mph in the UK.

: "Check the alternator one way clutch when the aux belt is off...." !!!!!

Had the same thing on a Passat B5.5 ver 1.1.1.2 which shore its aux belt tensioner mounting bolt off half a dozen times, the last of which it shore the timing belt tensioner mounting off and bent some valves- then it came to me.

Took some head scratching before the cause was found...

Tim..

Just done my Disco Alternator ... £50+ for a recon one, £74 brand new

100 Amp, so bought new and fitted myself. Now it's nice and quiet.

Mind, I'd waited 'till the rattling had become a clanging bell sound vefore I did it ... ;)

Apparently a common failure, so I read the other day.

Sometimes other things are added into the alternator. IIRC Vauxhall/Isuzu diesels have the vacuum pump in there, so they certainly used to be expensive.

I'm wondering, does my car have a vacuum pump?

On the TDIs / petrols or both???

If its a diesel, definitely.

All diesels do, don't they?

They can't draw a vacuum for the brakes etc off the inlet manifold like a petrol, IIRC.

Because as mentioned in my other post, a diesel can't use the pressure from the inlet manifold to generate vacuum for the brakes etc.

I believe it's to do with the higher compression ratio of a diesel, but could be wrong.

A diesel engine isn't throttled like a petrol engine, so there's no vacuum created for things like brakes. Diesels have a vacuum pump to make up for this.

There's no throttle on a diesel, so there's no significant vacuum in the inlet manifold. Unless you've got a truly stuffed air filter.
