This thread is filled with absolute trash of advice except for two individuals...
Very wise words and definitely words of wisdom.
There's no difference between a 2.0D vs a Civic when it comes to driving in high water. Diesel engines are not made from pixie dust and are NOT magical contrary to the popular belief.
Driving through the water whether it be in an auto trans or manual... you need to quickly push your way through it WITH a steady foot on the gas pedal. The worst thing you can do is "shift in nuetral and your car will swerve smoothly across the water", this WILL cause your engine to suck in water causing a hydro lock like a moron. Jumping the battery is insult to injury if your engine has sucked in water, rest assured, thats not the answer either.
Another idiotic suggestion, read above.
I'm sure you're a part of the growing trend of people that attach a RADIATOR HOSE on their muffler because they think it'll keep the car from getting damaged.
People listen to me very carefully... I dont know where all these misnomers come from in Pakistani culture but this has GOT to stop. Use common sense for God's sake. Key points to remember:
*Diesel engines are just as prone to getting water damaged as Petrol engines (I am aware that because they deal with higher compression that it would stand to reason they're connecting rods are strong and heavier, even then they do hydro lock!).
*Water getting into the muffler does not do ANYTHING! I have years of off roading experience that has left my truck completely submerged in water except for the intake and I've always pulled through without any issues. Fact of the matter is, a running engine automatically will keep the water from entering the muffler compartment to a point where it can damage the engine.
Hypothetically speaking, EVEN if somehow you came out side and your muffler (not the intake) was completely submerged in the water, your car will still start and push the water out, but if your engine is VERY weak, it *might not but will NOT damage your vehicle mechanically.
*You should try to avoid roads if its flooding outside, but if you do get stuck in a situation where there's standing water while you're driving.... try and drive right through it. Generally speaking, on stock vehicles, that keeps the water from collecting/standing near the intake suction area, keeping your engine alive. The slower your drive through it, the more the odds are of your engine sucking in that water causing a hydro lock.
*Every one should know what a snorkel is.
*Finally.... here's what your connecting rods will look like if you don't use some of the common sense listed above...
