Note: New and reconditioned cylinder heads of Fiat Punto are available from the manufacturer, and from engine reconditioning specialists. Some specialist tools are required for dismantling and inspection, and new components may not be readily available. It may therefore be more practical and economical to obtain a reconditioned head, rather than overhaul the original head.
1 During dismantling, it is essential that each valve is stored together with its collets, retainer, spring, and spring seat. The valves should also be kept in their correct sequence.
unless they are so badly worn that they are to be renewed. If they are going to be kept and used again, place each valve assembly in a labelled polythene bag or similar small container (see illustration). Number the bags or containers 1 to 8, or 1 to 8 inlet, and 1 to 8 exhaust, as applicable. Note that No 1 valve is at the timing belt end of the engine.

2 Remove the cylinder head of Fiat Punto Engine.
3 Undo the retaining nut and slide the timing belt tensioner off the mounting stud.
4 Undo the bolts and remove the thermostat housing from the left-hand end of the cylinder head. Recover the housing gasket.
5 On SOHC (8-valve) engines, if not already done, remove the camshaft and cam followers, and the spark plugs.
6 Starting with valve No 1. compress the valve spring using a spring compressor and extract the two split collets from the top of the valve stem (see illustrations). It may be necessary to tap the jaw of the compressor, directly over the spring, with a light hammer to free the spring retainer.
