Blew up my highside line...please help

vdubspeed on Sat April 26, 2008 1:58 PM User is offlineView users profile

Year: 1979
Make: VW
Model: Rabbit
Engine Size: 1.8
Refrigerant Type: r134
Ambient Temp: 80
Pressure Low: 32
Pressure High: 225
Country of Origin: United States

Here's the deal. Flushed everything. Bought new expansion valve, dryer, compressor. Pulled vac. Everything was holding tight and good. Started putting in the 134. Had two cans in when I went to remove the second I forgot to close the low side so when I unscrewed the connector from the 134 can I heard a hissing. I quickly closed the low side but I'm wondering if I sucked in air or pushed stuff out? Anyway...I went on to put in another can and change. Pressures were 32/225 but vent temp would only get into the mid 50s at best. I was hoping for high 30s/40s.

BUT that's not the real problem. After all the trouble I went through to measure 5oz of oil for the system and do EVERYTHING properly, my highside line made contact with the alternator!. It took no more than 1 minute for all my work to be pushed out into the environment. At this point I'm very dissapointed because I wanted nothing more than to get some decent a/c and now I've ended up costing myself more money, no a/c and not knowing what to do.

Do I have to pull everything again to measure the oil AGAIN? I guess I need a new dryer?

Very upset,

Jason

You dont have to buy a new dryer.

Just add back 2 ounces of oil, replace the busted line, vacuum, and recharge. You can add the oil inside the line or where it connects.

#%^t happens.

to late...already pulled everything(minus the condenser/evap)

I just want to make sure I get the right amount of oil in there. It really doesn't take long to put all the lines/compressor back in anyway. I thought the dryer was trash so I had it sitting out for the past two hours but I just capped it. Is it still good ya think?

I have about 3 oz of new oil left so hopefully there is some in the compressor which will get me back up to factory specs.

But that still doesn't explain why the prior results were so weak.

Thanks,

Jason

Were those pressures at idle? You still have the original style condenser on the vehicle?

yes...those pressures were at idle. The condenser is still tube and fin but a little larger. Are you thinking it's an efficiency thing?
TRB - do you agree with the dryer idea? I'm already going to refill the system with the correct amount of oil but I'm a little leary to reuse the dryer since it sat out for about 1.5 hrs.

The drier sat out for 1.5 hours, but there was no air flow through it.

It's not wise to leave a drier open sitting around. But what's the humidity level where you are located?

It's about 1000% percent. I'll just get a new one...there cheap enough. Only $7. The new line is what's going to cost me.

Huh. The junkyard tube & fin condensor will not get the job done. Imagine that.

Before you make up a set of lines for that boneyard part, why not replace it with a higher effeciency unit?

Good luck with your project.

Well they don't show it on their site but if they can find me the 12X26.5 inch condenser then I will order it. I figure since I need to get a new highside line anyway...might as well drop another $100 and try to drop a few more vent degrees.

Thanks all,

Jason

There are plenty of long, low condensors out there. Tim has a lot of parts that are not on this site, but can get anything you want.

VW abandoned the tube & fin early in some models, your GTI probably has a serpentine condensor. The 2000 Beetle has a good Parallel Flow unit.

There are others as well:





Good luck with your project.

Yeah I found it on their site after I did a search for the p/n.

Today I'll get a new condenser, dryer, some more oil and get a custom hose made.

I hope you're right about the condenser helping Bohica. Money is tight but if it is truely 25-33% more efficient and offers up to 5 degrees lower vent temps like I've read...then it will be worth it.

Thanks,

Jason

I can't locate dimensions on the 79 condenser. Before ordering the 2000 model. Make sure your fittings are going to work correctly or plan on having new hoses made for the newer style condenser.

No...I'm not looking at a 2000 model. I was looking for the universal condenser part number 12-0440C.

Unfortunatley ackits doesn't have any and I can't find anyone else with it.

I might just be stuck with my current tube and fin setup.
