Can someone tell me what the 2 other pulleys are attached too on the alternator belt (3rd one being the alternator itself)?

I assume it's job is just to turn the alternator keeping the battery topped-up whilst the car engine is running?

Crankshaft pulley.. centre bottom..

Left Hand side Power steering pump..

If you have another belt from crank to the right then aircon pump..

David,

I take it there's no markings or anything involved. Just as long as the belt is on each pulley correctlty and tension to between 45 & 90 degrees it's fine?

Only reason I ask is I had the alternator off last night and just wanted to check I've not missed something important.

Stefan

 

if it doesnt squeak the it will be ok

should be able to twist the belt 45- 90 degrees as you say..

Check tensioner is bolted up properly..

David

 

Cheers David.

 

Aircon uses its' own belt.

So is that the aircon pump to the right of it then?



Stefan

 

yes

Rob

 

cheers Rob.

I'm slowly getting to know my way around an engine bay

Stefan

 

I went a little further than you Stefan.

My exploring

 

aye, I saw that the other day. Your either a brave man or know what your doin. Hopefully you'll never have to do that again.

Any ideas what caused it? was it the timing belt being out of alignment?

Stefan

 

I reckon its a combination of the timing out & the fact the ECU had a Jap aftermarket chip which up'd the boost and was mapped to 100RON+, over time the car's been det/knock and I've not known, then BANG.

It won't happen again, I'll be gauged to the max & uprated metal to make sure it doesn't go BANG in my lifetime.
