It has the old R12 refrigerant.If it is low the R12 is not available anymore.However a product like freeze 12 will work with it.I could go on but,short if you do not have manifold gauges the old style for the R12 fittings you can convert the system over to the new R134 and a shop need to do this simply to remove the old refrigerant and add the new screw on fittings and charge up the system.Sorry for the long over answer,just forwarning you if the AC is not cold and what your next steps should be.

The alternator brackets on a 1986 Mazda B2000 typically use 10mm bolts. However, it's important to verify the specific design and any modifications that may have been made to the vehicle, as variations can occur. For precise sizes and specifications, consulting the vehicle's service manual or a parts retailer can provide the most accurate information.
The transmission fluid intake on a 1986 Mazda B2000 is typically located on the transmission itself, near the rear. You can find the dipstick tube for checking fluid levels on the driver’s side of the engine bay. To add fluid, you would generally use a funnel inserted into the dipstick tube. Be sure to check your owner's manual for specific details and procedures.
R134a
Should be R-134
Yes, you should bleed the brakes on a 1986 Mazda B2000 if you notice a spongy brake pedal, after replacing brake components, or if air has entered the brake lines. To bleed the brakes, start with the wheel farthest from the master cylinder and work your way to the closest. Use a helper to pump the brake pedal while you open and close the bleeder valve on each brake caliper or wheel cylinder. Make sure to keep the master cylinder topped off with brake fluid throughout the process.
Was built for R12, can be converted to R134a.
If it has not been retrofitted it will use R-12. If retrofitted it will use R-134a
Its best to use a set of a/c gauges but if you are not then just add the freon to the low side which will be the larger hose (suction side)...
