There would be a pile of crud when we left and the owners started asking us to wash it down after we were done. Common sense should be the key here, I would be very mindful of the aluminum coolers then anything on the engine. Remember, these things are exposed to water all the time.
There are pressure washers and PRESSURE washers. I too wouldn't put a 4000psi gas washer nozzle on the engine, but an 1800psi with a fan head on it delivers less water with less force than a garden hose with or without a nozzle on it. On an 1800 psi device you can easily put your hand in the fan spray 12" out of the nozzle (not closer). Try that with any garden hose sprayer and feel the difference in both pressure and volume.
