squeaky pulley..

hi there..

i noticed today that one of the pulleys from the front of my engine as quite a squeaker..

the water has run quite low as it was leaking very slightly from the top rad hose.. the expansion tank wasnt empty tho.

have i killed the water pump? it only does it on idle..

ta!

could be the bearing in the water pump pulley, they do wear and i killed mine not too long ago!

if its a 300tdi it'll more than likely be the Aux belt tnesioner, on the 200tdi, i have no idea, unsure if they have a tensioner or not!

D

ah yes forgot to mention its a 200!

had the pump off a couple of months ago doing the timing belt.. felt spot on then!

the tensioner is the alternator for a 200Tdi, loosen bolts, wedge a piece of wood between the block and the alternator, push across and tighten up.

Thats the badger way anyho

I think it's abit of both alternator and pas and stuff... Although I have been having a few issues with the alternator slackening its self off... Hmmm

well... it seems to have disappeared! il keep quiet!

Mate,

How much slack is in the belt?

well.. this is abit of an issue to be honest...

i tighten it up, and it slackens slowly but surely.. kept doing it, so i got a longer bolt and put a split washer under the nut.. but it seems to have slackend slightly again..

probably about 1.5/1cm of movement currently...?

Couple of quid for a new belt, might be worth replacing?

Iv had 2 in the past 2 months now! One shredded it's self, and I changed the other cos I thaught that it might be a dodgey belt.. Don't think it is tho!

A simple mistake to be made when fitting these belts is to misalign them via WP, alt & PAS pump. I assume it's all nicely in line, if not you can space out the alternator ( i found this is the culprit 90% of the time ).

If it's in line, a newish belt then other than oil/water ingress i'd keep up the slack in it.

The belts definately run properly.. Bloody does my head in! It's not easy to tighten either!

Mate, I had to wedge mine further using a piece of wood.

And leave the wood in there? I have been levering it out with a massive 1 1/2 spanner!

No, once I had levered it out and bolted it back up, I removed the wood.

im pretty sure when i swung on the spanner a couple of days later it shredded its self.. recon it might have been over tight!
