I agree with Malc, it's best done by someone who has done it before. I've recently bought a Gates kit for mine, belt, idler, tensioner and water pump for £180. I'm having mine done on the 12th by someone who has done them before (and for some reason enjoys doing them) all for £150 labour. Not doing the pump is false economy as a failed pump can take out the belt, and the engine with it. eBay seller called carpartsinmotion, delivered within 18 hours!
