Subject: How to drive your car in the flood Driving your car in the flood Dear Colleagues, let me share a bit of my knowledge. If you really-really have to drive in the flood, please read this carefully. Flood here means : water level reaching 1/2 of your tire size. Automatic Transmission ================== The tales say that car with automatic transmission are more vulnerable in the flood is NOT TRUE. One thing you can bear in mind : driving in the flood is almost similar with driving in mountain area like: Lembang, or Puncak, a road with high degree of elevation. If you push your throttle too deep, will not give you any advantage and adding risk to the engine to shut down. Similar with driving in the mountain, if the elevation is too high, you will not climb because the power is not enough. And water, the stronger you push, the stronger the water will push you back. So, DON'T PANIC. What you must do : 1. put the transmission in the lowest gear (D1, or 1, or L), and drive your car moderately, watch the RPM , as long as the needle is between 1500 to 2000 RPM, you're fine. Do it with the lowest throttle you can reach the RPM, no need too push too deep. THE WATER WILL NEVER EVER GO INTO YOUR EXHAUST PIPE, even though the pipe is underwater as long as your engine running, so, don't worry. If you need to stop for a long time in the flood, quickly shift the gear to N, and keep the engine around 2000 rpm 2. turn of the AC. You can push off or turn to the maximum left of the temperature controller of your AC. You can keep the fan running. If you turn on your AC, the cooling fan will possibly suck the water from the front, and spray it into your engine compartment. 3. keep the distance with the car/bike in front of you so you don't make a sudden stop (which you may not do that because the brakes are wet) 4. know your car, know the location of the air intake. This is very important, because if the water sucked into this part, you can say goodbye to your car engine, the piston will break and the engine will go dead foerever before you overhaul it. Know the position of your ECU (the engine control unit - like the brain of your car). If the ECU covered by water, you need about 2-4 million to replace it. (ECU is used in a car with electronic fuel system, not using carburator) Conclusion : Don't drive in the flood if the water level is almost reaching your air intake. Don't worry about the exhaust pipe. There's some vulnerable-by-water part of your engine, those are: * Alternator. Alternator is a part to recharge your battery/accu. If the alternator broken by water, the worst thing is only the car battery is not recharged. But you will still can drive it home or somewhere else. But this part is usually placed high enough and covered by other parts. * Electric fan of you're a/c system. Don't worry, it will not stop you. Manual Transmission =============== You don't need to push the throttle deeply to have very high RPM just to make your engine runing. 2000 Rpm is enough. You're just wasting gas if you do that. You must do similar with the tips above : 1. drive in 1st gear only, keep the rpm around 2000 RPM (avoid doing "setengah kopling"). 2. keep the distance with the car/bike in front of you. 3. turn of the AC 4. know your car's air intake position, and ECU. (first version of honda jazz have the air intake position facing down and this is very not suitable for driving in the flood, cos it will be the water sucking port to your engine) General suggestion : If you are not sure with your car's health, and happened to stop in the deep flood for quite a long time (1/2 to 3/4 level of your tire) - for say 2-3 minutes, do total oil change (engine oil including the oil filter, gearbox oil) because the water could be inside the engine already. If you are not sure with the water depth, and still want to drive over it, stop a while, get down, look far away in the front, measure the water depth by looking at the water level compared to the other car's tire. Happy swimming. Don't panic Enjoy the adrenaline ! But if you can avoid the flood, please do so :
