My buddy was mudding in his jeep yesterday beside a pond. Needless to say he got brave and decided to go into the water, it sank. Now he has water in his engine oil, intake was full of water, and probly everything else. He said he killed the engine as soon as it became submerged. He's going to change all fluids, is there anything else he should do.
Pull the spark plugs before you turn it over for the first time or you may hydro lock it and bend a rod. We submerged one at work and it killed and that is all we did.
Yep, do what I do to my jet skiis when we flip them. Pull the spark plugs and crank it over. It will push the water out of the cylinders. Drain and change the oil and fire it up.
Was water ingested through intake of did it seep into engine from sitting submerged?
drain, flush, all fluids (including tranny, and diffs) repeat, then repeat again, dry all electrical connections with a hair dryer, use dielectric grease on all connections. If fuel tank was submerged drain all fuel, and dispose of properly. use a drying additive for the tank.
Thanks for the advise, I wouldn't have thought about pulling the spark plugs. Hopefully she'll fire right up. Water also go into the carb. would that cause any problems?
For the carb, Sea Foam works wonders. It'll displace and force the water out of the intake while your cranking with the plugs out. Another thing that will help protect the cylinder walls while doing this is squirting a small amount of 80W or 90W gear oil in each cylinder it also helps displace the water. It'll smoke like a bitch, but that'll burn off. He may want to clean or replace his spark plugs and definitely put some anti seize on them when re-installing them.
I noticed that Brandon mentioned hair dryer on the electrical connections. You can also spray with WD40. The "WD" in WD40 stands for water displacement. It works wonders in that department and does not conduct electricity so there is no fear of shorting things out.
I found this out riding my Seedoo and getting my remote for the tow vehicle wet. Couldn't disarm the alarm until a guy with some WD enlightened me.
You might want to pull the alternator and put it in the oven for an hour at 225*F...unless you choose to take it apart and dry out the innards with a hair-dryer.
I think we should also evaluate this vehicle at this point in time!!! Is it like most mudding Jeeps you see on the net or is it a daily driver/showpiece? Evaluate your time and money vs the vehicles worth
Well thanks for all the input guys!! I'll let yall know if we get her running. Its a 2002 or 03 model Jeep, very sharp. He was very, very upset at himself for being talked into taking it mudding, but it was him who entered the water. I'm sure after its runnig (hopefully) well all look back at this and laugh, hopefully.....
I do that same type of job several times a summer lake side when we flip the skis over. It's amazing how far that water shoots out when you crank it over. They start rough and then clear up just like you described. Glad you got it going again.
