Removal and installation of cylinder heads of 1.4i/1.6i engines (Fiesta 2)

Removal of the cylinder head is carried out in the following order:

Disconnect the ground cable from the battery.

On the 1.4i engine, remove the air filter.

On the 1.6i engine, disconnect the intake hose from the cylinder head cover.

Drain the coolant into a previously prepared container. If the coolant has been in use for less than two years and is not contaminated, it can be used in the future. In order to drain the coolant, it is necessary to disconnect the lower hose from the radiator.

Disconnect all flexible cooling system hoses connected to the cylinder head.

Disconnect all electrical wires from the cylinder head.

Disconnect the gas pedal linkage.

Remove the bolts securing the front exhaust pipe to the exhaust manifold.

Hang the exhaust pipe on a wire.

Remove the upper cover of the timing belt that drives the camshaft.

Set the piston of the first cylinder to TDC.

Loosen the camshaft timing belt tensioner and remove the belt from the belt pulley mounted on the camshaft.

Remove the spark plug caps and unscrew the spark plugs.

Loosen the cylinder head bolts, starting from the bolts on the edges and ending with the bolts in the middle.

If the cylinder head does not separate, it can be lightly tapped with a plastic hammer. It is not allowed to insert any tools between the cylinder head and the engine body.

If there is water and oil in the cylinders, remove them.

The cylinder head is installed in the reverse order. When installing the cylinder head, the subsection on assembling 1.4i/1.6i engines may be helpful. Fill and bleed the engine cooling system according to the instructions in section 2.8 "Cooling system". Check the thermostat operation.
