Am I missing something or why does your ls have the coolant reservoir separate by the airbox? Did they change that for a particular year? Mine is annoying I have to remote the air duct each time I need to fill a little bit of coolant. I hate how mine is integrated into the fan shroud.

He removed it to install the cold air intake.

You got it! My friend totaled it so I used it. Shut those damn injectors down a little!

That's not what I'm referring to. Look closer. He has a coolany reservoir right there where we have a air box. I remember mine being on the fan shroud.

It's a French car.

Toyo, I've never had any moisture issues either using water to clean engine. Over 20 years, on 4 LS's, over 700K+ miles. Dealers do same. I think those who've had problems put cold water on a hot engine, which is just asking for trouble.

The time I pressure washed my engine it was cold and had been sitting for hours, purposely. I even tried very hard to avoid all the electrical connections. Eventually, when it all dried out it was OK but I'm not a fan. Too easy to get water where it should not be. Plus, it is bad for the environment. I will only use the rag and cleaner method from now on. Spraying down the engine bay gently is not as bad as pressure washing. Search the net, lots of horror stories. It may not of happened to you but it has to many people.

I think you're asking for trouble when you hose down an engine or steam clean it, those systems just weren't designed to handle that. Just too many sensors and electronic connections on modern cars. On older cars in the era of carburetors, it made more sense, there was a lot less to go wrong, and they were usually a greasy mess anyway.

I know many detailers have done it without issue, but I just don't see the point to tempt fate with a car like this. I'd rather just have a bit of dust on it.

I just take a wet rag and something like Simple Green and spend a little time wiping it down. If I get my car detailed, I tell them specifically not to steam clean the engine.

Definitely not worth it to hose it down. As others have said, there are many components in that area that were not designed to withstand being hosed down, let alone being pressure-washed. It's not very practical to pressure-wash or steam-clean the engine.

However, it is very practical to use a mild degreaser to wipe clean the surfaces you can see, because you tend to lean over these areas when doing any sort of maintenance in the engine bay, and you'd get your hands/clothes dirty if these areas are never wiped down.

I wouldn't apply any dressing that would attract and hold dirt. Maybe some sort of synthetic, plastic-safe sealant to repel dirt and to make wipedowns easier next time.

The top dressing and wipe job is nice if you're just doing it to please you eyeballs. If you are doing it for a cleaner and easier to work on engine without junk on it don't the sides and bottom of the block come into play?
I'm wondering if careful and a lower pressure cleaning with a pressure washer might be done if careful. No spraying of the looms, coil packs or anything else electrical. Spray the block sides and from the bottom with the plastic shield off. Isn't it all about doing it carefully. What are the thoughts?

What did you do? How?
