Notes On Washing The Engine

CAUTION:
Danger of damage and injury.
- Never wash the engine when it is running.
- Only wash the engine when it is cold.
- Protect the oxygen sensor connectors from moisture.
- Components sensitive to moisture (e.g. electrical components like ignition coils) must be adequately protected. Cover them, if necessary.
- Never direct a high-pressure lance directly onto engine components.
- Ensure a minimum clearance of 30 cm is maintained between the high-pressure lance and engine components.
- The water temperature of the high-pressure lance must not exceed 80 degree C.
- The water pressure of the high-pressure lance must not exceed 100 bar.
- Any servicing labels (e.g. oil change) and safety stickers must not be destroyed.

How To Wash The Engine







Special tool Engine lid with cut-out No. 9635 for engine washing.

NOTE: For environmental reasons, the engine may only be washed in car washes equipped with an oil separator.

1. Remove engine lid in accordance with the instructions, retaining the maintenance cover to the interior in place. Opening and closing engine compartment or refer to "Boxster - Boxster S" Driver's procedure.
2. Remove any maintenance labels affixed to the engine (e.g. oil change schedule tag) and replace after work is completed.
3. Protect components sensitive to moisture, possibly by covering them with plastic sheeting or bag. Oxygen sensor connectors must not get wet.

NOTE: Engine cleaning agents must not attack plastic or rubber parts.







4. Spray engine top and bottom with an appropriate engine cleaning agent -figure- and allow it to work in. Observe the application time specified on the cleaning agent data sheet.

5. Pre-treat persistant dirt manually (e.g. with a sponge or brush).

NOTE: Always make sure that no washing water enters the vehicle interior.

The illustration applies to steps 7 and 8.







6. Fit special tool Engine lid with cut-out No. 9635 in the same way as for the engine compartment lid.
7. Protect vehicle interior against ingress of washing water with a cover film or the vehicle's own engine compartment lid. To do this, set the engine lid upright as a protective wall for the interior and prevent it falling down with an adhesive strip to the convertible top.







8. Guide the high-pressure lance through the wash opening provided for the purpose -see figure- and clean the engine from the top. Ensure a minimum clearance of approx. 30 cm is maintained between the cleaning lance and engine components. The water temperature must not exceed 80 degree C.







9. Raise the car and carry out the washing procedure from underneath -see figure-; the bottom engine cover does not need to be removed.
10. Dry sensitive components (e.g. electrical plug contacts) that become wet with a lint-free cloth or gentle jet of compressed-air.
11. Moving parts in the engine compartment, such as the catch hook for the bonnet, must be regreased.
12. Seal the engine surface with a special engine wax or corrosion inhibitor.
13. Re-affix the servicing labels.
14. Fit engine lid and close convertible top.
15. After washing the engine, carry out a test drive, paying particular attention to rpm fluctuations or misfiring.
