Once again we have found ourselves confined to the comfort of our own homes. We trust that you’ve managed to occupy some spare time to do meaningful things, be it reading, cleaning the house, play computer games, binge watching movies, or learning to cook. There’s more time now to cultivate new hobbies, but since this is an automotive website, we’ll keep the topic relevant.
The subject pertains to car care, or more specifically, the not-so-delicate process of cleaning a car engine bay. Over the years, there have been multiple videos of car wash centres hosing down an engine bay with water, sometimes even with a pressure washer! Most of the time, these were met with a lot of flak from the community, but really, it has been going on for decades.
Is it really okay to hose down an engine bay with running water? Will it damage any mechanical components, or will it cause some of the electrical circuitries to short? We reached out to Proton for official comments.
Generally, Proton says it is not harmful to run a stream of water over the engine bay, provided you follow some basic but crucial dos and don’ts. What you don’t want to do is use a pressure washer, because the pressurised stream can find its way past gasket seals or plastic covers that protect sensitive components, usually electrical.
Before you even consider cleaning your car’s engine bay, first make sure it is cool to the touch – never wash or clean while it’s hot. Hot metal expands and can crack in direct contact with cool water, and that’s just the least of your problems, really.
You’ll also want to cover any electronic or electrical components, such as battery terminals and the fuse box with some form of protective film, like a cling wrap for example. Also be sure to close off any open air ducts, and seal the air filter cover tight.
For an extra peace of mind, consider protecting your alternator as well. While it is designed to handle splashes of water from regular driving, it isn’t meant to handle large amounts of running water at one go. There have been many reports of alternator failures resulting from flooding the engine bay with water, so consider yourselves warned.
Once you’re certain these conditions have been met, Proton recommends using a low pressure garden hose to remove loose dirt. Don’t be too generous with the stream of water, though, just use however much is required to get the job done. You may also go over stubborn grimes with a soft bristle brush. After that, remember to wipe things dry, and refrain from starting the engine immediately if you can (some drying time is recommended).
There are other, much safer ways to go about cleaning the engine bay. There’s a myriad of dedicated cleaning products you can buy online, and all your car usually needs is a few microfibre towels and the good old elbow grease. A simple cleaning process takes around 15 minutes, so we much prefer going this route than flooding the heart of your vehicle with water.
We’ll put together a simple do-it-yourself guide soon, so stay tuned for that. In the mean time, where do you stand on the matter? Have you had your engine bay cleaned, or God forbid, damaged with a stream of water? Let us know, below.
