Baha: To cross or not to cross ??

[1D4LV]

ako nagpapahupa muna. di ako tumutuloy. kung nasa office and based sa news eh baha sa mga dadaanan ko, dito na ako natutulog.

kung naka labas na, nag-skyway na lang ako. hehehehe.

As much as possible avoid the often flooded streets of Metro.

Things to remember when fording high waters:

1. Slowly enter the water not more than 1500rpm.
2. Make a bow wave or use as a buffer the bow wave the car in front of you.
3. The higher your rpm, the higher risk you stall. (radiator breakage due to shattered fan blade, fan breakage, electronic breakdown due to splash of water; air filter-intake water seapage).
4. Maintain you rpm just enough for your vehicle to get thru the flood & avoid entry of water in the muffler.
5. If possible, make a vacum space in your car by closing your windows.
6. Do not try to ford the water if the flood is higher than the height of your tires.
7. After exiting the water, try to pump(bomba) your breaks to make it dry.

does not apply anymore to vehicles with electric motor driven auxilliary and radiator fans.

It still applies pa din kasi the higher the rpm(the more speed you have), the more splash created inside the engine bay thus entry of more water inside engine(air intake, spark plugs etc.)
Usually, a 1500rpm will suffice than say a 2000 to 2500rpm. But I guess it depends on a case to case basis especially if its incline etal.

By the way, it also depends what vehicle you use. Some vehicles needed higher rpms than the rest. Diesel vs gasoline, Traffic and terrain, etc.

dapat hindi "rpm" sinabi mo since electric driven radiator fans have constant rpm and is independent of engine rpm. dapat speed, as in kph.

sa discussion dati parang hindi naman kailangan i-rev yung makina pag tumatawid. it seems that it's just a myth

there was even a photo of a pajero idling with the tailpipe completely submerged in water.

Sir Yebo, not debating you on this but it should be still based on rpms pa din and not speed cause some vehicles have variable speed sa spedometer(change of tires sizes). Secondly, just like you said, electric driven radiator fans are independent from engine rpm hence we can base it on "rpm" and not in "kph". What I did mentioned a while ago is the "rpm" of the engine and not the "rpm" of the fans(electronic or engine driven). I hope this clears up Sir.

can anyone confirm this?

paano kapag napahinto ka sa gitna ng baha? what should you do?

let your gear stay at 1st gear, engage the clutch then just idle?

or shift to neutral then just idle?

while crossing... dapat hindi ka naka apak sa clutch dba?

[mikaztro]

Just to give you an example, river crossing * low idle.
