After a spirited drive my Tuscan is squeels pretty badly when I start it up.

Assume this is just the fanbelt - is it easy to adjust? Can I do it myself?

Makes you look like a pillock on a bright summers day with the roof off when it sounds aweful when you start it!

Mine squeals slightly on cold start, but I would not tighten any further as I do not want to load the aux shaft any more. This is the alternator belt, and after a run, the battery should be in good condition therefore load on it would be less. For my money I'd be inclined to believe it is power steering that is hot start issue, either way you need to get your tensions checked. Pretty easy job, but make sure the belt tensions are equalised across shaft.

or er - sounds more complicated than I thought.

Is this a specialist garage job?

No disrespects but if you own a TVR I would suggest you get some basic mechanical knowledge under your belt or you may find your wallet will be getting emptied quite quickly. The tensioning of a belt is not really a specialist job like a TVR engine is not a specialist engine.

You are just led to believe so.. so as the "specialists" can charge special priceswink

Really not complicated. Just trying to ensure you go through the whole cause and effect scenarios. Effect is belt squealing, cause could be it is loose, but need to ensure it is not anything else. In the same way that if your kettle stops working (effect), the cause could be the blown fuse but before blindly replacing it you should consider why it was blown.

Sorry if this sounds like egg sucking

By asking if this was a job I should attempt myself I thought that was what I was attempting to do.

Modern engines are not as easy to tinker as older ones with so it’s not easy to get this ‘basic mechanical knowledge’ you speak of – despite my interest and enthusiasm.

If there was such thing as a Haynes manual for the SP6 then, after establishing if was in my realms, I would not hesitate to get my hands dirty.

I’m definitely hampered by being the only car enthusiasts of all my friends – they all drive around in dull, overpriced, rep-mobiles.

Time for some new friends me-thinks.

When is your next service? Alternator belt should be adjusted as part of this. Mine used to slip, wasn't sorted on first or second service with main dealer, only sorted when I went to indie, even then I was told it can be difficult to achieve the tension required because there is no tension pulley as such. As with yours, used to slip when hot, presumably due to belt expanding with heat from engine whilst parked-up. OK nowsmile

I started a reply giving instructions how to do it, but realised it would probably sound a bit Heath Robinson. The problem is being able to get enough force to tighten the belt, as there is no convienient place to get a fulcrum for a lever. I use a piece of wood on the Tamora resting one end on the engine and the other on a suitable solid piece of car, and then lever the alternator up with a nail bar. Does the trick. Hope this gives you a rough idea.

I have braved it - bonnet off now, air box removed.

You can see the Alternator belt giving when you start it.

Spoke to APM who said there should be no defection in it at all - very tight is the answer.

Willyworm - thanks - you give me a concept of just how tight it needs to be!!
