Help! Submerged hood of car in deep puddle during downpour. Next steps?

[BlackNTan]

So I was stuck at the gym in a massive downpour (not Isaac) and decided to head home the long way which is usually free of large puddles. Well, I manage to miss one and saw water wash across / cover the hood of my ZHP. I got home (about 300 yards) without any sputtering and came right to the mafia page. Should I run the car for a while to heat up the engine more? Leave it alone and see how it does in the AM?

I did a quick web search and found a lot on how to escape a submerged car, but not what to do in this case. Any sound advice would be much appreciated!

I'm confused.

You're worried about having a large puddle wash over the hood because you're scared of water in the engine bay or what?

[BlackNTan]

Yeah Udub, Am worried about water getting into air intake and other areas of the engine. Does the fact the car continued to run after imply I'm in the clear or do I need to worry about subtler damage I won't see for days / weeks.

Probably water soak worries.

You're fine, water takes path of least resistance. You think it wants to travel through the bumper and into a cluster engine bay or simply go over the hood?

Yes, you probably have some water in the bay but it is what it is...you have to put the car through a lake to watersoak an engine, given oem intake

Yeah, I'm not judging your concerns here but I'd have to think BMW's engineers did everything they could to minimize any kind of soak, even in extreme conditions (unless this is a well known problem I am unaware of).

I've done my fair share of driving in inclement weather, never had an issue and I've had some BIG downpours do the same thing. You should be fine.

Make sure you go wash her, road water is nasty.

Thanks guys, you make me feel a lot better. I live in a part of the country where we hear of a lot of folks destroying their engines trying to drive through water-logged roads. I think my few seconds submerged may have just seemed like a looooong time!

Yea you are good dude, hydro lock occurs pretty quickly. If anything was going to happen it would of almost instantly. No worries

I did this one time except it was a lot worse - to the point where I was in so much water the clutch started slipping. Had the diff fluid changed just in case anything got in there. Everything was/is fine. It was butt clenchingly scary.

Drain oil, tranny, and diff fluid. Refresh all. Upgrade suspension to Koni FSD or KW/Bilstein PSS's. By new rims and tires. Done....no more worries.........

Pop hood. Check intake filter. If it's dry...no concerns at all. Also recognize that the intake housing sealed with a clipped rubber gasket (I'm sure you know this). If it got in through the centerline hood scoop....just check the filter. That's what I would do.
