6 million dollar A/C...
well, not quite.....my 87 190D 2.5 N/A was recently converted to R134 and a replaced condenser, new CCU and a host of smaller items by a very good indy here in Denver. I simply didn't have the time and its getting HOT here! $2200 and 2 weeks later BOOM! My manifold hose on the pressure side gave out. I just got a quote for nearly EIGHT HUNDRED DOLLARS for a new manifold hose. Anyone have a better source for these? Any luck with a race shop etc. making a replacement? Gotta be SOMEONE with a better solution to the slightly higher pressure of R134 conversions.......Anyone? anyone?

slightly higher 134a pressure means the system is overcharged. this has got to be the number one mistake by diy's and pro's alike. 134a suffers from a bad reputation because most people who use it don't know what the hell they're doing. if you don't believe me read almost any ac thread or post on this site. very few of them are helpful and most are full of overblown opinions of people who are either inexperienced or just ignorant. i've worked on auto ac systems for 25 years and made the switch to 134a with no problems that weren't inherent to older systems as well. whoever charged you 2200 dollars to work on your system and now wants 800 bucks to replace a hose is a very talented individual, but his talent obviously has nothing to do with ac repair.

Yeah, i stopped reading half way thrugh, you spent 2,200 US $'s and changed it to 134???????????? Change it back to R12 after replacing the parts that failed.

Ask ackits.com to provide you with a quote to rebuild the hose assuming no other damage and the fittings are in serviceable condition. It should be less than $200, probably a lot less.
If it was the original hose, no wonder it blew out. The original rubber was about 20 years old. The new lined hose material is recommended in any case for impermeability to R-134. Got to wonder if the altitude of Denver places additional stress on flexible items like hoses and seals. |

I just purchased a new a/c hose assembly for my 1987 300E for about $357 from www.***************, if this may help. Delivery in about 4 days UPS.

Thanks to almost everyone...
for the thoughtful input, it is much appriciated. The vast majority of folks make this site a truley valuable asset, and enjoyable to be a part of. Some folks think its better to opine about how much you paid and thereby maybe implying they sit a bit higher on the stool of life. The question was about A/C Manifold hoses. Not "Do you think I paid too much?" If ya REALLY NEED TO KNOW why I have $2200 in the system so far, I'll tell ya. I ASKED FOR IT! I told Mark @ Stu Ritter, a VERY good indy, to fix my A/C. The PO had fried a bunch of wiring due to a half-assed attempt to bypass EVERYTHING and hot wire the Compressor directly, 3 hours went to basically rewiring the system, the CCU fried, I ASKED FOR NEW and got it. Klima fried as well, not real cheap. Receiver/Drier, all new switches, PER MY REQUEST. New condenser due to massive leak. New Expansion vavle as well. Kinda see were this is goin? I wanted it to work, I OK'd EVERYTHING. Any more questions?........

In my professional oppinion R-134 works fine when it has been retrofitted properly |

When retrofitting R-12 to R-134 I have always followed the manufacturers written instructions (for good reason) and I have seen few failures when the instructions are followed to the T. Now contamination from mechanical failure and or the use of unusual refrigerant blends (the low cost alternative mixtures that only reek havoc in the automotive repair world-especially with recycling equipment) I will do several (6-10) of those in a year. As an extra precaution when I convert the AC system from R-12 to R-134 I always go a few steps further mainly because I am from the old school of AC repairs. I flush the condenser, the evaporator and all the lines as best as possible. When the flushing is complete I install a new expansion valve and a new receiver drier as well as new pressure switches (always). I also R&R the AC compressor-drain it and then refill it with the prescribed amount of oil (unless the comp is getting it's triennial replacement. Regardless of what a vehicle is willing to pay for a repair their expectations for the repair to be performed well seem to always be much higher-meet and exceed their expectaions and charge accordingly simple as that |

Now that takes talent and courage, talent to ghetto engineer the rig and then courage to be seen driving around town in it....
