Perfect timing...

Tonight im leaving work early to get the timing belt back on and try to fire up the engine. As im changing the timing belt, the timing marks i set are useless as i marked them in relation to the belt/cams.

Thankfully Fiat have made it easy! There is a mark on both the cam and crank pulley, and a corrisponding mark on the block and head.

Crank timing marks. Also pointed out is where the TDC sensor is positioned.










Cam timing marks. There is a notch in the cylinder head.














In theory, aligning these marks and putting a new timing belt on with new tensioner, at the correct tension, and it should fire right up. The timing belt tension should be such that on its longest length it can only be twisted by a 90 degrees. If its too tight it will squeel, to loose and it will slip and destroy the valves! No pressure.
