Do you put PAG oil into accumulator?
Do you put PAG oil into accumulator?
To add oil to a system that is under a vacuum. Put the yellow charging hose in a container of PAG Oil, 0pen low side valve on guage manifold slightly. the vacuum will draw the oil up the hose into the accumulator, just don’t let the end of the hose suck air or you’ll be pulling in vacuum all over again.
How does the accumulator work on a Ford Ranger?
The accumulator/dryer holds excess PAG oil, removes any moisture in the refrigerant using a desiccant and catches any liquid refrigerant that has not boiled into gas yet (Liquid refrigerant going into the compressor will hydro lock it, just like taking water in the intake of the truck).
What do I need to fix my Ford Ranger air conditioner?
You will need access to some special tools for this fix. You will need an A/C manifold gauge set, and a vacuum pump to evacuate the system. You can buy the manifold gauge set at AutoZone or O’Reilly for about $90 or Harbor Freight for about $50.
When do I need to replace the accumulator on my truck?
It is also recommended the accumulator is replaced whenever a compressor is replaced as well. Buy the needed parts. You can order a new accumulator from suppliers online, your local auto parts dealer, or from your vehicle manufacturer dealership parts store.
When to change the accumulator in a refrigeration system?
Since the accumulator contains a desiccant to remove moisture from the refrigerant, if the system has been discharged and improperly recharged or needs recharging, changing the accumulator will help ensure the system works efficiently after recharging. It is also recommended the accumulator is replaced whenever a compressor is replaced as well.

How does the air conditioner work in a Ford Ranger?
The engine is what runs the compressor. If there is enough static pressure (the pressure in the system when the A/C is not running) which is over 75 psi, and the electromagnetic clutch is working, when you turn on the A/C, the clutch will engage the compressor which pressurizes the Refrigerant gas.
Where is the clutch on a Ford Ranger air conditioner?
The compressor clutch is controlled by the use of the pressure transducer switches. If the pressure gets too high, the High side transducer (located on the manifold bolted to the back of the compressor) will open and not allow the power to the clutch until the pressure drops back down.
Do you need to replace pressure transducer in Ford Ranger?
For the component replacement sections keep this important fact in mind: If you do any component replacement other than the pressure transducer switches or the clutch, (ie opening the system) you will need to replace the accumulator/dryer. If you open the system to the air for more than a few minutes you must replace the accumulator/dryer.
