Stupid Mistake

Asked by Apr 19, 2016 at 07:26 AM about the 2014 Hyundai Elantra SE

Question type: Maintenance & Repair

I got stuck in water yesterday and got my 2014
Elantra towed home. I was told to take the air filter
out and let dry over night. I woke this morning and
put the air filter back in and still won't crank. How
bad can the problem be?!!?

Was it running when it went in the water? If so the problem can be very bad, if enough water got in the combustion chamber it can break Pistons, crack heads even break a block cause water will not compress so all that pressure finds the weakest spot and breaks through, what you can try is remove all the spark plugs, disable the fuel pump, and see if the engine will crank over, if it does without making any horrible noises then see how many cylinders pumped out water, if they do blow water, add a small amount of oil to each cylinder and run a compression test, if compression is good, then you will have to service the engine, oil and filter, check the transmission make sure water did not enter there, if it did then change that too. If compression is too low or zero on any cylinder then engine damage had occurred and it time for the pros to take over. Note you may have damaged some of the electronics also so just be aware of this so your not surprised when it comes up.

Ok. If water got into the engine it is bad if it was running, water does not compress so it breaks things, engine will have to be checked out for damage, have it towed to a shop you trust, be aware that water can also damage electronics so be prepared for that also. This may get expensive. Is that better? Being a tech we tend to get too technical.

Thanks so much!!! I really appreciate it!!!!
