Hi. Sorry, I'm a bit new to this. Is there anybody who can help me with a belt tensioner problem I've got with my 306 please. Thanks, Stan.

Auxiliaries are just the alternator and the power steering (no aircon). It's a 1.9 diesel on a 1999 306 LX. The problem is the belt tensioner isn't in line with all the other pulleys and guides. I've just bought the car and it had a knackered belt so I bought a new belt and fitted it but I've only done 30 miles and the belt looks the same as the one which was still on it - frayed to bits. Could it be the tensioner is bent somehow? Or maybe the bolt which holds it in has come loose and it making it crooked? It's not noisy and everything else seems ok. If I've got to change the tensioner, how tricky is this to do? Not much clearance between belt and body so do you have to lower engine or something? Any help/advice would be really appreciated. Thanks.

Possibly worn tensioner or pulley throwing the belt? Not massively difficult, wheel off, inner wing off gives reasonable enough access. Check that there is nothing interfering with the belt and that all the other pulleys are running freely.

If you get stuck let me know I think I've got the haynes manual about somewhere (had a couple of 306s). If I haven't I'll have a look at the EPC I have on my laptop.:thumb:

Thanks. All the other pulleys and guides look fine. Pretty sure it's the tensioner causing the problem - it's pushing against 3/4 of the width of the belt leaving 1/4 hanging over the edge of the tensioner. If it was worn, would it be this far out? Is it possible it's bent out of shape (maybe from somebody over-tightening the tension adjuster previously?) I'll take a good look at it tomorrow, this only happened tonight, but I know I need to do something to it before I fit another belt, otherwise the same thing's going to happen. Is it just one bolt holding the tensioner on? Does it just simply unbolt? Sorry so many questions, never done one of these before. Cheers.

If you post the last 8 digits of your VIN I'll have a look tomorrow and get the precise layout and setup and what tensioner is on it. My last one had A/C as well so was a bit different I think as the tensioner was offset and set by an allen key (10mm I think). What's your location by the way?
If you aren't sure about posting your VIN on open forum my email address is in my profile just click on my user name.

I'm in North Devon. I'll find the VIN and let you know, thanks alot. The tensioner adjustment is an allen key bolt then a 13mm nut which pulls the spring (I think) up or down. I've no idea how the spring attaches to the tensioner wheel, guess I need to take it off and have a good look at it. Thanks again mate, the diagram would be really useful, I'll get back to you with the VIN. Cheers, Stan.

Had a good look at this today and found the tensioner bolt had come loose. If I'd noticed this when I changed the belt then I could've saved myself the cost of a new belt. Anyway, I know for next time and won't make that mistake again.
If anyone else is finding they're getting through belts, it's worth checking the tensioner bolt. I guess it's obvious to check it, but this is the first time I've had this problem.
Thanks again for your help mate. Cheers, Stan.
