I purchased my panda about 5 years ago and the dealer had fitted a new timing belt. After this length of time I decided it probably needed doing again so I purchased a kit and put it on the shelf pending a suitable time to do the job. As my ex wife used to say 'the road to hell is paved with good intentions' and I didn't get round to the job for 5 months. I started striping the covers off and realised the kit I had was the wrong one, after a little research I ordered the correct kit and a set of engine locking tools for this engine. The job was going fine until I tried to fit the crank lock (having first locked the camshaft), it was about 12cms out and would only fit when the belt was moved around 1 tooth. It had also been obvious when removing the cam cover that this had never been off since it left the factory. My only conclusion was the dealers mechanic had taken a few shortcuts and fitted the belt 'by eye' and got it slightly wrong. With the car back together it's running fine and I've just done a regular 300 mile trip and achieved a fuel consumption of 58mpg, the best I've managed in the past was 50mpg. How much would a 15% saving on 5 years worth of fuel have been? I suppose the moral of the story is to use a trusted mechanic or do the job yourself and always use the engine locking kit, I bought mine on ebay for about £20.
