ENGINE ALL

1	The engine and engine compartment must be preserved after every cleaning.	Applies for vehicles up to 12/89 and in the period 6/93-7/94
2	The fresh air openings, the windshield and the front fenders must be generously masked off before cleaning and preserving.	The form and materials for masking are to be determined by each workshop itself. Masking is necessary in order to ensure that no materials whatsoever, e.g. cold cleaning solvent, wax or similar, penetrate inside the car (difficult to clean).
3	The screw joint holding the brake fluid reservoir must be masked off with adhesive tape, which is to be removed again after preservation of the engine compartment.
4	Mask off the ventilation hole for the diaphragm chamber in the pressure control valve in the cylinder head cover.	Engines 601, 602, 603	AP01.00-P-8503-01A
5	Cleaning is to be performed when the engine is no hotter than hand-hot (at the exhaust) using a demulsifying cold cleaning solvent (short action time) and a high-pressure hot-water cleaner, depending on how dirty the engine is.	"Demulsifying" means that a mixture of oils and greases in water separated in the oil separator pipe.
6	When cleaning the component compartment behind the engine compartment: Spray only as much water as necessary under very low pressure.	Electronic control modules must be covered beforehand; any that become wet must be dried afterwards.
7	After washing/preserving the engine	Lubricate throttle control linkage and check for ease of movement and wear.
8	Preservation is to be performed only when the engine compartment is dry and using properly functioning commercially available equipment.	Only use approved wax preservation agents. Airless devices produce the least contamination.
9	Do not spray the following with preservation wax:	Electrical and electronic components, belt drive (belts and pulleys), exhaust pipe and muffler in component compartment.
