Also note, if your truck is not a 97, research the capacities for the oil and refrigerant before starting, and make adjustments to these instructions to fit your particular truck. I am going to write this in sections. Mazda sells versions of the Ranger as the B-Series pickups with minor styling and equipment differences. There will be two o-rings at the evaporator end and two o-rings at the refrigerant line end, plus one o-ring for the low pressure transducer.
If flushing the component on the truck, be sure to put the catch can at the lowest opening. Turn the engine off and release the quick connects.

Check the connections where the hoses hook into the components, and the compressor around the pulley, valves and hose connections. Ford owns a controlling interest in Mazda. I basically replaced everything but the evaporator, condenser, and the pressure switches. Do not add any more than this!! You can leave the end that is attached to the inner fender in the truck. With the engine hot, your vacuum pull time will be about an hour or so, 2 on the very hot and humid days. Noticed a few small drops of oil on the driveway about two weeks go.

Part to be replaced: Orifice tube Located in the lower tube coming out of the Evaporator core. See replacing of compressor below. Well, I hate to tell you this, but your compressor is worn out and is not building pressure on the refrigerant. The overall advice given will apply to other engines and years as well, but you might have to make some adjustments mechanically.
Two rear-hinged rear doors are optional on SuperCab models and require that the front doors b. Make sure your new orifice tube matches the old, and pitch the old tube.
