Huge Mahalo to Blitzkrieg Bob..I have A/C!

[HIe34]

So after months of suffering in the Hawaii humidity, I finally have cold A/C. With the help of the island guru, we found two leaks at the expansion valve and refrigerant line fitting above the expansion valve. Replaced o-rings and tightened up expansion valve, added refrigerant and oila!

Hated to take time away from his clock/grill project, but I am forever in debt.

Thanks buddy.

Is the expansion valve serviceable without removing the dash?

how hard is it to add refrigerant yourself? i have never done this and my system needs a recharge.

If you system is running R-134 refrigerant, then you should be able to purchase the necessary fittings and cans of R-134 at most autoparts stores. Once you have the tools, you only need to find the proper high and low side connections under the hood and fill the system according to the specs provided either under the hood (on a sticker) or in the service manual. If you are running R-12, then you'll need to first change the drier and then evacuate the system with a vacuum pump. After that its once again the basic charge procedure. HTH

Thank you. How would I know which refrigerant my car is running? It's a 91.

unless it's been converted.

Ther should be a sticker by the front of the radiator regarding the A/C fill.

Look at the fittings. If they are small and threaded like tire valves, then you got r12.

If they are bigger and like pneumatic snap on fittings then you got r134

A general rule of thumb is the change over from R-12 to R-134a was 1993 on most vehicles. Typically there is some sort of identification under the hood specifying the type. If you do have the R-12 it is gonna be really expensive to service, as liquid gold is probably cheaper. Even R-134a has tripled in price over the last few years.
