Can you spray water on your engine?

This weekend, I plan to give my Jeep Wrangler a top-to-bottom detailing. But I’m leery about the engine bay. Can you spray water on your engine?

As long as you take some precautionary measures, it’s usually fine to spray water on your engine, especially if you have a modern car.
Newer cars tend to have protective covers over vulnerable components, and the cabling is likely waterproof. But you’ll have to stick to using a garden hose rather than a high-power pressure washer to avoid damage—and stay away from spraying sensitive components such as sensors, air intake systems, and alternators.
If your Jeep Wrangler is an older model, you should take even more care. Not only are components in older vehicles likely not weatherproof, but they also may have wear that makes them susceptible to water damage, particularly from pressured water hoses.
If you’ve installed aftermarket parts in your Wrangler, such as cold air intakes, be careful. If these parts are not waterproof, you can wind up doing some real damage to all that wiring you’ve had installed.
