Engine Size: 1.5l
Refrigerant Type: 143a
Hi, I bought the charging kit from Wal Mart, and it consists of a hose with a brass coupler at each end. One end is supposed to slip over the car's a/c port, but the port is just slightly too big. the kit came with a bunch of adapters, and the brass coupling fits on one end of one of the adapters, but the other side of the adapter does not couple with the port - i think that adapter was for "retrofitting, haha" and r12 system or something. i checked my manual, and the car definitely is 143a. this must be a very oddball size port. has anyone heard of this, and what can be done - thanks, paul.
I discovered the problem. Apparently there is something called a high side, and a low side. I was trying to put the 134a into the high side, which can cause the can to rupture. i have to look and find the low side, which should be a threaded fitting, and I believe my kit will probably have the adapter to screw on to this.
Don't charge blindly. Also NEVER charge any sort of a "stop leak" product (use only plain R-134a). Those two reasons are enough to return the whole mess to Wal-Mart and invest in some proper tools before proceeding.
Both the high side and low side on a R-134a car are standardized push on fittings. They are different sizes (low side is smaller) so people won't as easily blow themselves up with a Wal-Mart kit (they can still ruin their car's A/C system though).

It sounds like you have never fooled with an AC system. You cant just shoot it up and have it work properly and you should have a basic understanding of how the system works to prevent some very expensive damage to the system.
I'm recomending that you read up on AC systems before you mess with yours. Does anybody know if the site sponsor sells AC repair books? Your next choice is the library or the auto parts store.
