How to Clean an Engine
Observance of all environmental protection regulations is required.
Information on suitable cleaning and protective products is available from any authorized Detroit™ service outlet.
Use the following minimum working distance between the high-pressure nozzle and the surface being cleaned:
Approximately 700 mm (28 in.) for circular pattern jets
Approximately 300 mm (12 in.)for 25-degree flat jets and dirt cutters
Do not use compressed air or pressurized water to clean or dry the engine if any part of the engine is disassembled.
Power clean the engine as follows:
- Allow engine to cool down to room temperature before spraying the engine.
- Thoroughly clean the entire engine using a steam cleaner or high pressure washer with mild soap and warm water. To prevent damage to engine components, keep the water moving at all times while cleaning. Never direct water onto electrical components, plug connectors, seals or flexible hoses.
- Once the engine is clean, blow the electrical connectors dry with compressed air to remove most of the standing water.
- Allow the engine to dry completely before making any kind of repair.
- Ensure that there is no standing water in any electrical connectors.
Warning: EYE INJURY
To avoid injury from flying debris when using compressed air, wear adequate eye protection (face shield or safety goggles) and do not exceed 276 kPa (40 psi) air pressure.
