Blown hose

After putting the transmission pan back on, and filling with a couple gallons of ATF+4, I cranked the Jeep up and was about to roll it off the ramps when I heard a loud pop. Turned the engine off immediately, fearing I'd done some irreparable damage somewhere. Went around to check out the engine and found this hose busted. Looks like it comes out of the AC compressor.

Can I get a confirmation of part and part number? Thanks in advance.

I think I found the part after a bit of digging and research. High pressure discharge line, compressor to condenser. Part #: 55037801AB.

Hmmm...it probably is the AC-Suction line

Charles it would be appreciated if you would add the year of your Jeep to the signature line. :waytogo:

Sounds like my luck. Do a simple oil change and end up having to replace a cracked radiator.

Actually it does look like AC discharge #9 in diagram.....55037801AB.

You're right TC! I should fill out my signature line. Thanks for the heads up.


That's the correct part #. Ordered from rock auto for $32, napa had it for 55. Planned on doing more research before I dove into the replacement, but is there anything I need to know before hand when doing this?

Don't allow the compressor to run vent modes only or..Unplug the compressor clutch coil wire harness connector.
The lines are under high pressure & contain harmful vapor & mist. Refer to a factory service manual for more info.
Consult a qualified refrigerant auto specialist for service & line replacement.

Most likely your system is completely discharged now and open. You should change the dryer and the line with the orifice.

The line will be here today, and I planned to install it and recharge the system. What is the reason for replacing the accumulator/drier along with the line?

I'm not proficient with the technical side of all this. I also can't afford to take it into a shop where they'll be charging me $120+/hr labor costs, which is why I opted to change my transmission filter/fluid and the serpentine belt on my own.

Thanks for the help and info!

there is desiccant in the dryer so once the system is open it can become very quickly saturated from humidity in the air.

I suggested the low side line where the orifice tube is located inside as stuff from the explosion may have been caught. Also might as well change it since your system is open as well as a PM.

you should evac your system. can get a vacuum pump from autozone on the loaner program. Make sure it can hold the vacuum.
