One of your questions as stated and not answered is:
What is the recommended thing to do if you need to pass through an area that's been flooded?
The answer to this has nothing to do with Mechanics.SE, but I'll answer it anyway ...
Bottom line: DON'T DO IT.
It has nothing to do with whether your car can run through the water and survive. It has ...
The term you're looking for is Wading Depth which is specified by the manufacturer. They may surprise you, and its info you should know about your vehicle. Its in your manual, or search it online.
Jeeps say 500mm, and some models go to 700mm
Mercedes GLC SUV has a wading depth of just 300mm
Landrover Discovery (not the more compact Discovery ...
Generally the car shouldn't be driven through water! On your Yaris, where you had high revs, what would happen if your air intake was submerged would be that your engine would fill some cylinder(s) with water and since water doesn't compress it would bend a piston. This is called hydro locking and is often a catastrophic failure. So don't do that if you want ...
There are a lot of variables here, but key risks are:
water shorting electrical systems
water being sucked into air intake (or potentially into exhaust)
cold water coming into contact with hot metal causing thermal shock
The first one is very dependent on where and how wiring systems are routed and protected. Fuse boxes, connectors, battery etc are ...
Later, they will sell the car to a sucker
And that poor sucker will have constant electrical problems, which cost them thousands in attempted repairs, and ultimately lead to scrapping of the car.
If you don't believe that, I've got a perfectly nice flood car to sell you!
Modern cars are highly electrical. They are more of a computer with an engine ...
I'd try the following things:
Vacuum it out (imho the best solution, as you can also clean the air filter housing)
Use a flexible pickup tool (photo attached) and try not to lodge it deeper, as poking aimlessy will certainly be counterproductive
Remove the air filter housing and shake the wipe and remaining debris out.
"The Icon's air filtration system is N95 certified, which means it blocks at least 95% of small particles that measure 0.3 microns."
This sounds really impressive.. and I suppose it is, from a certain perspective. However from your perspective:
All I care about for purposes of this question are pollutants
It's less impressive. Why? Because much of the ...
Some vehicles, by their very nature, are more drive-able in deep water than others. Back in my young and exceptionally stupid days, I lived on a small peninsula that was surrounded on 3 sides by Long Island Sound, which is salt water. The main road that ran down the center of the peninsula had a low spot that was flooded twice a month during high tides, ...

This is a very basic answer. All engines need air to operate. Both fuel and air are mixed in the combustion chamber ...
