Customer Question

I have a 2004 CLK 320 and I went through a large puddle of water at speed and the water came over the front hood. I continued driving the car for about 5 miles until I reached home, where I turned it off. The next day I could not start the car. Over time, a couple of days, I wore out the battery and since the car has approximately 97,000 miles I have replaced the spark plugs, bought at the dealer, installed a brand new battery and changed the air filters. The car will still not start. A couple of times when I have attempted to start it the starter goes and then stops and the belts do turn but just for a second. Other times it turns over but doesn't start.

HI,

I am sorry that you have not been helped yet. I just came online and saw your question.

There is a possibilty that it is hydrolocked. Were either the spark plugs or the air filter wet with water when you replaced them

The air filters were slightly wet when I replaced them. The spark plugs were not wet but as I said in my initial question they had approximately 97,000 miles on them.

HI,

Ok, with the air filters being wet, this means air was sucked up thru them and into the intake manifold and then into the cylinders.

Remove the spark plugs, pour 1-2 tablespoons of automatic transmission fluid into the the spark plug holes and let set for an hour or two. Then put in neutral with parking brake set and use a socket and breaker bar on the crank pulley nut and turn engine over several times by hand. Now reinstall the plugs and try to crank
