So there I was..... going up an easy road kind of rocky but nothing bad considering Dodge Caravans were going up (although I'm sure they were grinding most of the way). There's a "Y" in the road that we slightly pass, "oh crap, we're supposed to go that way". Back up, BF says "just don't hit any boulders haha". Stop, proceed forward slowly, not going very far, Patriot rolls back and then horrible noises, steam coming from under hood.

A rock, not too huge but about 2 feet in the widest spot is lodged between the passenger side bumper and the ground. I must have started rolling over it and didn't make it because I wasn't going over too fast and when I rolled back it came up and ground into the bottom of the bumper (inches from the skid plates of course) and pushed the bumper up into the A/C lines. It was wedged in so tight that we had to push the patriot off of the rock. Wish I had taken a picture because it was a totally freak thing but I was too busy cussing thinking my radiator just bit the dust. Plus the horrible noise almost made me want to puck, still don't know exactly what that was except maybe the compressor. It stopped after heading back down the road a bit but still doesn't sound right.

Soooo....haven't really surveyed the damage yet but it looks like the A/C suction and liquid lines may have been affected. I have the service manual that I downloaded from here but it's hard to identify the parts since I can't find an general overview pic. Has anyone ever had to replace these parts? I've identified the accumulator and it's the plumbing below and to the right (towards the driver side) of that. Is it going to be a major pain in the rear end and should I have someone else do it or should me and the BF be able to handle it (minus recharging the system)?


For those that care to know, I was on Rainbow Road (off of Fall River Road, Clear Creek County, Colorado) getting ready to turn off to head up to Chinns Lake.
 
That sucks! I jacked the bumper near the AC too but didn't do any damage to the lines. I would definitely have a professional make the repairs - the AC system isn't something to mess with.

here it is

So there is a pipe running down from the accumulator and it crimps to a black piece of rubber which crimps to another tube on the other end. What happened, I think is that when the bumper pushed in, it pushed the metal line that connects to this rubber piece, pushing it up against to what I think is the compressor wheel. I think this is the suction line that has been torn apart.

So, fixable by me, or 'yeah right, get a mechanic"?

Thanks Dawson. I probably will have it fixed by a pro anyway, well at least a neighbor that is a mechanic. I just want to know a bit more about so he isn't like "well, your discumbobulator is stripped and it will be $500 to repair", lol. Not only that, but lord only knows what was jacked elsewhere that I'm not seeing.
 
LOL, your "discumbobulator"!

Damn, that's crazy, we've had ours in so many ridiculous places and haven't had a problem yet!
 
Thanks for the heads up. This might be a prime location for a retro-fit to add a metal sleeve over this portion of the line so this doesn't ever happen to others. Looks like worse case for you is a new line, a system evacuate, and some freon. You may want to cover the hole until you get it fixed to avoid trashing the compressor or receiver drier (which may have to be replaced anyway if it's open to the air very long).

I don't know, I think I would rather have to replace a $40 part then have metal smash into the compressor and have to replace the compressor.

Thanks for the heads up about covering the hole. Good ole' duct tape. I'll do that ASAP.

I think what would be a good idea though is to extend the skid plates out on the right and left side of the current skid plate (FDII that is).
 
You can do AC work yourself, but it's not easy, and you'll need to purchase about $100 worth of tools to do it right. Since the system has been opened to atmosphere for so long, you also want to replace the accumulator because the accumulator has a desiccant bag inside it that absorbs moisture. You would need an R-134a Gauge set and a vacuum pump, ideally you'd want the system flushed too (since the pulley chewed through the hose, there could be rubber debris in the system now that could harm the compressor or clog something somewhere). I would just have a shop do the work personally, but pick up the parts yourself to save some money.

Attached is the exploded parts view for the AC System, the suction line (low side) hose is part number 05058151AB (#1 on the diagram) and the accumulator is 05189376AA (#22 on the diagram).

www.wholesalemopar.com has the suction line for $28.25 and the accumulator for...hmm I think they call it a Dehydrator for some reason, $13.92.
