Can water get into a car engine through the exhaust pipe?
Yes, but not always!Since the exhaust gases are flowing outwards through the tail pipe, Water won't enter into it, even if water get inside the exhaust pipe [silencer] water won't reach the engine since it's mounted far too high for the water to reach.But if the driver suddenly make any changes in the engine speed[while shifting gear or slowing down], water can get sucked into the engine as a result of the back pressure created in the exhaust pipe due to the sudden change in engine speed.So if you happen to drive through a water logged roads, then shift to the lower gear so that engine will run in higher speed and as result more exhaust pressure is produced, which will prevent water from entering the pipe. Maintain a good engine speed, and never change gears or apply clutch until you pass the water logged areaOnce you passes the water logged areas, make sure all the electricals and breaks are working just fine, and continue your drive.. !!
Will leaving my windshield wipers on drain my car's battery?
you heard wrong ! once the key is shut off then the current is cut off from the wiper motor.
What happens if you get water in the engine cylinder?
depends on how much and whenIf a small amount is ingested while the car is running it’ll probably just turn to steam due to heat and blow out the tailpipe. This is often what happens when a car has a head gasket leak and the coolant finds its way into the combustion chamber.If a big gulp of water gets into the combustion chamber (let’s say you drive through a very large puddle and the car sucks up a bunch of water) you’ll likely destroy the engine. Unlike air, water does not compress very well so if the cylinder fills up with liquid water (even partially) when the compression stroke happens that piston will likely stop dead. And with all of the other rotating mass that is already going things will break. Connecting rods most likely, but pistons, wrist pins, etc. All in all, very bad. (this is a condition known as hydrolock)If the engine isn’t running and you had the plugs out and got water in there no real damage unless you let it sit for a long time and rust. Take the plugs out, run the starter for 10 seconds or so and most of the water will blow out the spark plug holes. pour a teaspoon of oil into the cylinder, crank it again to get it spread out and then put the plugs in and start the engine. you’ll get some smoke from the oil and moisture but that’ll go away pretty quickly.
The coolant light in my car is on when I turn the car on but will turn off after driving for a bit. Is that normal?
Hey Adam, thanks for the A2A :)I had a Ford Escort wagon that used to do this on me on occasion …usually with the change of season to colder weather.The coolant level in your expansion tank is low …but not low enough to keep the light on all the time.What’s happening?With the first start of the day, the coolant is cold and is at it’s smallest volume. The coolant, as it cools, draws back into the engine block from the expansion tank. In your case, the coolant level drops just below the sensor for the coolant light …and the light turns on. After you start the car, the coolant begins to warm …and expand in volume. As the coolant expands it will begin to fill the expansion tank to a point where it deactivates the sensor and thus the light on your dash goes out.I suspect if you check the expansion tank when the engine is cold …prior to the first start of the day …you’ll find it’s a bit low. Simply add the proper type of coolant or some distilled water to the expansion tank up to bring the level up to the “COLD” line on the tank. You may have to check this a few days in a row, prior to the first start, to get the coolant level stable at the “COLD” mark.
If 75% of engine wear occurs at the start of your journey how do you prevent problems?
75% engine wear is not the same as 75% engine life. One good way you can do to lessen engine wear is to keep your car maintained and most importantly ensure the engine oil is within recommended level. Anyway today's automotive engineering has reached a high level of low engine wear.
What is the issue for a bike not starting after a heavy rain?
Water logged ignition ’d be my speculation. If u have access to a hair dryer, it may help to dry out wiring, specifically spark plug and coil/magneto wires. Also check ignition points or spark inducer, remove discover and use hair dryer. All these components and wires must be dry and not frayed or damaged. Good luck and try to locate wet area, so you can protect it from water/rain in future.
What will happen if I do not replace the fuel cap on my car?
Most modern cars have an evaporative emissions system which, as the name suggests recovers evaporated fuel in the tank which would otherwise vent off into the atmosphere. This system has become a standard for environmental reasons, as it reduces the amount of pollutants making it into the air. Without the gas cap, your car will likely present you with either a check engine warning light or a more specific gas cap light since the car interprets the lack of a cap as a faulty EVAP system. In extreme cases where a car without a gas cap has sat in an enclosed space, fuel vapor can build to the point of being fire and / or explosion risk.To remedy the warning lights, risks, and pollution replace your gas cap. The lights should turn off after several miles.
My car was in a minor flood but appears to be driving fine. Could there be any hidden damage?
In New Jersey this past weekend we had some pretty torrential rain. This rain lasted for days. While out driving my 2000 Toyota Camry in said rain my car got stuck in a flood (which I drove into unknowingly. It did not look nearly as bad as it really was). I tried driving my car through the flood but it eventually stalled out. I sat there for a few minutes not really knowing what to do, meanwhile, water was starting to trickle into the vehicle from the bottom of the door. I think the water level was about halfway to 3/4 up the wheels, I know they were never totally submerged. After a few minutes I tried starting the car again (not recommended, yes I know) and the engine came on. I was able to drive my car safely out of the flood. Once I got out of the flood I pulled over and bailed out the water that had collected in the car, it was deep enough to almost submerge my feet when they were flat on the floor. This happened last Saturday (today is Thursday) and the car has been driving fine ever since. The only thing out of the ordinary is that the airbag warning light has come on, even though the airbags were never ejected. I plan on taking the car in to get detailed, and to get the carpets cleaned. Is there anything else I should ask the mechanic to do? Is there anything else that I should be looking for? Do I have any potentially disasterous surprises in store for me?
