My airconditioning fuild R134 drained last week. I had a leak from one of the high pressure pipes.

I managed to get a welder to weld a aluminiun bead over the small hole. My question is:

Can I drive with no R134 in the system. I will not turn on my A/C.

I heard mositure can get into the system and ruin my A/C?

Any recomendations?

 

Yes you could drive without charge in you A/C, beside even if you turn on your A/C the compressor will not turn on due to low pressure. Moisture could ruin your a/c, vacuum your system before putting freon.

 

Like LEVY said, no problems with driving with no AC charge.

The "dryer" can go bad when being exposed to moisture, the part is about $100.

Is your car a 95? In the US all 93-94 FDs have R-12 systems.

 

hey thank for the replys,
and my car is a 94, the hood sticker said R134.
I will try to get charged up next week sometime.

 

Evacuating the system to 26inHG will cause the water to boil off. You'll be fine unless you drive around with water inside the stuff for a while and the metal lines rust out.

 

my ac doesn't work either.. but oh well.. driving through the hot summer with the windows down is fine...

 

my ac sucks really bad when i turn it on it makes my car stall out, i got a 95

 

Your ISC solenoid is probably bad.

 

R134a was added to rx7's in 94' only 93's had r-12. You'll be fine without having any refrigerant in your system as long as you had them pull it into a vacuum. If not the air and moisture in the system will ruin your reciever drier because it is a dessicant bag and will absorb all the moisture and it will bloat.

 

For the record, SOME 94s have R-134a. Some more were converted after leaving the factory, too. You have to check what's in your car.

Ummm, what are you referring to? Aluminum doesn't rust...

 

Yes always check first, thanks Dave.

 

yup my 94 came with r-12

 

how much will it cost to get that fixed????

 

The solenoid is a couple hundred bucks. Labor is removing the UIM and simple replacement. The ISC is right near the elbow/UIM junction on the firewall side.

 

Any reason you're suggesting a new one at that price, when a used one is a quarter that amount?

 

Unless you're talking about an air pump or something like that, I wouldn't buy used parts. Just me.
