This past Sunday...here in Ftlauderdale...We had the mother of all rains...it literally rained for 4 hours straight. Everything was flooded and deep flooding to boot. Right outside our shop a 2013 Dodge charger with a 5.7 hemi came flying down the street and sure enough...Hydro locked the engine.
He proceeded to push that car out of the lake (no pun intended) and into my parking lot where he asked us to look at it.
We fully thought the engine would need to be replaced!! We rest of this story is the absolute truth!! We sucked 3/4 gallon of water out of his intake...the intake manifold and all of the cylinders after removing all 16 spark plugs. We put a little trans fluid into each cylinder and hand turned over the engine from the crank to see if there was any obvious engine damage and it didn't seem like there was any. We replace all the plugs with new ones and also had to replace the starter (he kept trying to start it while the starter was under water).
Put it all back together and tried to start it and the engine fired right up and ran like a dream. I don't know if there will be any lasting electrical problems from the water but that engine ran like a champ. Got to give it to Dodge engines.
