my v70 2002 helppppppp

[dazmun]

Hey peeps

need some advice

now my car has started making some really strange noises
from the engine , kind of like a bearing being crushed with a fan belt kind of squeak and strange hum, now i took it to my good local garage and they said they are about 80% sure its the alternator and needs replacing

does this sound right

daz

[cameron]

Does it make more noise the more you rev it ?

It does sound like an alternator to be fair

[jimka]

or the aux' belt tensioner.

[dazmun]

no not really

it used to do it for like 30 sec and then stop
now its getting worse sound like a big frog in a rain forest under the hood

[cameron]

Yeah thats a good point actually J.

I had a strange noise from down that area ( rattly at a certain rpm ) and i had to replace a tensioner, will the garage charge you to investigate further ?

[dazmun]

well they have said thats what it is and not given me any other options
it does it at around 1000 rpm, and if i put it in gear it is a bit more noise
it is a really strange grinding sound and squeak dosent sound like a loose belt

[cameron]

Not the belt mate the tensioner itself

[thebadger]

My car had a squeal at low revs, it would go away after 10 mins driving.

It was the aux belt (the one attached to the alternator) which was duff & the tensioner was replaced too. Also got te cam belt done at the same time.

Don't fret, the sound is pretty loud when the tensioner is shot.

[jimka]

yes, and when they snap they quite often take the cambelt with them (they get tangled up) so just go careful, just before it snaps (if you let it get that far) the steering will go funny (belt to the power steering will be reduced/non exisitant) and the squeeking will get very loud) i suggest stopping rather promptly as its a sure sign that the pulley has seized.

a new one and belt shouldn't be more than £150.00 from an indi volvo garage.

To check if it's the alternator, start the car & remove the negative lead from the battery.

If it cuts out then you have a problem with the alt. I reccomend the police spec 110A replacement if it has.

[dazmun]

hey hey
so it was the alternator 300 quid lighter now but a lovely v70 that also seems to have more grunt than ever

thanks guys

[thebadger]

Did the battery trick work?

And did you get the police spec 110A alternator?

[dazmun]

no mate
i think they took it out and tested it
i have one other problem they couldn't fix
my re windscreen jet dosent work, its not the fuse they think it might be a short in the wire but could be expensive as they would need to take the panels out to find the problem arggghhhhhh strange thing is that it doesnt come up on my onboard computer

[thebadger]

Ok, that's different.

It may be that the pump motor is either seized, or the turbine (bit that makes the water move) may be gunged up. Over use of screen wash can sometimes do that.

Do you have headlight washers too? If so check that the hoses are all attached. If one has come off, then any fluid could just be streaming out the hose & loosing the pressure to power the jets.

The tank filler pipe can be pulled out (you need a torx driver T25 iirc to detach it from the bulkhead) then you can pull the filter (sock) and look into the tank to check for any blockage. You could check the hoses too just incase it's something blocking one of them.

hey badger
wanted to run something else past you
as you have a very similar model to me
when you keys are not in the ignition and you put your foot on the brake pedal do your brake lights come on???

what was really strange today drove my car came out tonight and my rear lights were on , turned car on all fine turned off again and no problem with the rear lights being on

can you shed any light excuse the pun

[phil_woods]

On my v70 if you have the lights on sides they stay on without the key. Put them on dipped and they go out when the key comes out.
I don't know if that's relevant but thought I would mention it

[thebadger]

Yes, I can also light my break lights with my foot on the break pedal, even without the key in the ignition.

Though I have an ex-plod so many electrical "quirks" are found in and about the systems.

It may be something that can be switched on & off with a softwear upgrade (as most bits on the cars do!).
