4. Remove the cooling fan without hoses.
5. Remove the radiator, radiator grille, warm air duct, engine shield, accessory drive belts, drive belt cover, and remove the spark plugs.
6. Turn the crankshaft so that the piston of the first cylinder is at TDC, and from this position turn the crankshaft a quarter of a turn to the right. Put on an interchangeable socket (wrench) on the crankshaft bolt to crank the engine. You can also jack up the front wheel, engage a gear and turn the wheel until the crankshaft is in the described position.
7. Remove the toothed drive belt as described in next chapter.

V6 engine
20. Camshafts can be replaced with the engine installed on the vehicle. The work is the same as when removing the cylinder head, until the shafts are removed from the heads. Both distributors are different.
21. The shaft with the drive gear of the ignition distributor belongs to the right row of cylinders. Not all V6 engines have the same camshafts. If a new shaft is ordered, it must be suitable for the engine «Z7W» Espace.
