Preparatory actions and list of repair procedures (Honda Civic 6)

Clean the engine compartment and the outside surfaces of the power unit using one of a wide range of special solvents. This treatment will prevent dirt from getting inside the engine.

If necessary, depending on the nature of the work to be done, the bonnet can be removed to provide free access to the components to be repaired (see Chapter Body). Cover the car fenders with special covers or just old blankets to avoid accidental damage to the paintwork.

If a suspected vacuum loss or leak of oil, coolant, exhaust gases, etc. indicates that the appropriate gaskets or seals need to be replaced, virtually any of the listed procedures can be performed without removing the engine from the vehicle (in situ). This applies to procedures for replacing the intake manifold and exhaust manifold gaskets, oil pan, cylinder head, and both crankshaft seals.

Dismantling, repair and installation of external components and attachments such as the intake manifold, exhaust manifold, oil pan, water pump, starter, generator, ignition distributor and fuel system components can also be carried out in situ.

Since the cylinder head can be removed from the engine without first removing the power unit, repairs to the camshafts and valve train can also be carried out directly on the vehicle. In addition, the timing belt and gears are usually replaced in situ.

In an emergency, it is permissible to repair and replace piston rings, pistons, connecting rods and connecting rod bearings of the crankshaft without dismantling the power unit. However, this opportunity should not be abused due to the difficulties associated with maintaining cleanliness and the need to carry out a number of preparatory procedures.
