Has anybody ever washed the engine on a [DSM]?

Many people who experience problems immediately or shortly after washing their engine have damaged the crankshaft angle sensor on the car. Without this sensor, the ECU cannot tell what position the crankshaft is in, and the engine cannot run.

Usually, people who wash their engine are able to cover the electrical sensors prior to washing. If this is done, the engine will probably start up fine right after washing. However, driving the car with a wet engine will create steam, which can get inside the crankshaft angle sensor housing. Once the car is shut off, the steam condenses into water, which wrecks the sensor.

Some owners are able to 'revive' their sensors, but most are dead. Some Digesters have investigated if they can be repaired, but so far nobody has been able to do so.

To prevent crank angle sensor damage, either wait until the engine is mostly dry before driving, or drive it for a while and then raise the hood to allow the steam to escape.

Here is one way to do the engine:

** Important. NEVER USE A PRESSURE WASHER **

Start with a cold engine.
Run the engine until the engine is warm to the touch.
Shut the car off.

Place plastic bags / Saran Wrap / Baggies over the

• Alternator
• Cam Angle Sensor
• any other sensitive electronics

Choices of cleaner:

• Scrubbing Bubbles has been reported to work very well and safe for painted surfaces. I like the Foam as it clings as it cleans and easier to see.
• For more stubborn areas, diluted degreaser (or natural degreaser like orange).

Spray and scrub the engine. Avoid getting water in the electrical connectors.
Use a light mist of water to rinse everything.

Once done, remove the bags and either wait until dry or start the engine (at your own risk) again with the hood up. Let the water evaporate.

OPTIONAL: Once the engine is up to temp, if you like your rubber (and painted parts) shiney (NOT THE BELTS!), spray regular Armor All on them, then go for a non dusty drive. In 30 mins, the heat applied to Armor All will have coated the rubber in shiney even coat.
