I plan on taking my Jeep 4 wheeling eventually. Before I do that I was wondering what all of that dust and mud does to your intercooler. With my TJ I have forded some pretty deep creeks and have been totally coverend in mud. (Thats a different tale) However with an intercooler hanging around I'm concerned that mud would gum it up so bad that it be damaging to it. I've never had a Turbo before so maybe I'm way off here. I just prefer measure twice and cut once. Thanks Merry Christmas Chris |

As far as "gumming" it up, not that big of a deal. It will have the same effect as getting your radiator full of gunk, since they are almost identical in construction and purpose. Radiator: runs coolant through it. Fins take away heat. Intercooler: runs air through it. Fins take away heat. Now getting a puncture, that is a whole different story. |

Should not be a problem, you can have a turbo without an intercooler, it just won't be quite as efficient. If you do get a punture (boost leak), however; you will eventually ruin the turbo. |

Had mine in about 20 inches of water and muck, hasn't been a problem in any way. |

Not to hijack the thread. But, if you are worried about water and muck gumming things up. Note the new air intake. Older liberty’s where built with there intakes mounted high, above the radiator. This has been moved to a much lower position. The new air box now takes air from behind the head light. This concerns me more. You are more apt to suck crap in at this height. I don’t know when/why DC made the change. If it’s something with the CRD or the gassers have this new air box too. Jeepin Al and I where comparing the two. We held the two different air boxes side by side. The dimensions of the two boxes are the same. Just the goose neck from the older one is gone. There are no different hoses or other components in the way. So we put the older style into my jeep. That was two weeks and 1,600mi ago(on the road all week for work). So far no problems. Now the engine is now better protected from deep water crossings. Jason |

Some engineer with head up his behind thought the turbo would need a better flow of air and didn't know that turbo's are not effected in the way a normal asperated engine is with air flow. Lot of people make the same mistake, this engine with stock airbox on dyno then with no airbox and you might see a 1/2 hp difference, where a similiar N/A gas engine might gain 10% increase in hp from opening the airflow. It's a failure to understand the dynamic's of a turbo or supercharger. |

Just curious. Might it be that they repositioned the air intake to get pre-warmed air from the radiator? |

Don't thing so as the opening is in front of the radiator and then turns and goes behind the head light. I was looking at it a couple days ago and wondering how hard it would be to route to a higher pointy that's not a direct straight on air intake. The reason being I was looking about doing it is heavy rain injestion will driving down the highway. However our VW's did the same thing without ever causing us a problem, but I don't remember either of us ever being caught in one of those heavy down pours on the highway. |

This shouldn't be a problem with the other box. The intake is covered by the hood. This gives it even more protection. The two air boxes have the same mounts three pegs that snap into grommets on the fender. We reused the original lid (I didn't note if they are different but the hinge and locking clamps are the same). The entire assembly just snaps in. You can pull one out of an older KJ or get from your stealer-ship. Jason |

If you do get your radiator and or intercooler clogged with mud, and you'll know when it over heats on the way home, just wet (not flush) the mud with a garden hose. Then use compressed air to blow the mud out of the fins. Too many people use water pressure to force the mud out of the radiator and intercooler. THIS WILL CAUSE FIN DAMAGE. I learned this the hard way on a tractor. Compressed air will save the cooling system and it will save you money in the long run. You can rent an air compressor or buy a small one cheaper then you will be able to replace these parts. Happy Jeeping. |
