Retrofit a 1989 Ford Ranger Air Conditioner
The 1989 Ford Ranger pickup Motor lorry was unreal with an R-12 freon air conditioning transaction, and this coolant has because been replaced industry-wide with 134a. The 134a coolant causes less damage to the Universe's atmosphere and is further notably cheaper than the R-12. Converting the Ranger to handle the 134a is a straightforward method and should cut the morals backyard mechanic approximately an day to adequate.
Instructions
1. Acquire the air conditioning system evacuated of all coolant by beguiling the Ranger to a garage or oil pennies effortlessness; these shops are compensated for collecting the coolant and Testament usually not charge for it. All the ancient R-12 coolant must be removed from the course before adding the 134a, owing to the two cause not merge fresh and decreased performance or leaks may ensue.
2. Connect the nipple adapters included in the retrofit equipment to the grand and low side nipples on the air conditioning operation. On the Ranger, the low coercion Harbour is on the evaporator, near the passenger firewall. The giant energy edge coming to the battery has the high rise side Harbour on its uppermost bend. Replace the can of spent coolant with a can of compressor lubricant oil. Repeat the procedure of discharging the can into the system. When the can is spent, replace it with another can of 134a coolant and allow it to discharge.
3. Refill the system using the retrofit kit's valve or by purchasing the 134a refill kit with an included valve and several cans of coolant/lubricant. Turn the engine on and set the A/C to its maximum setting. Connect the can of 134a coolant to the valve by turning it clockwise into the base, then connect the hose's nozzle to the low side port adapter from Step 2. Open the valve and the can will discharge into the system. In about five minutes, the can will be emptied. The nozzle can be removed from the low pressure port. The glum adapter is for the low side, and the giant side gets the burgundy coloured adapter. Under orderly conditions, it Testament not be cold to access the high pressure lines, but adding the red adapter will make it easier for shops to perform maintenance on the system. The adapters simply turn clockwise onto the existing nipples and can be hand tightened with a pair of pliers. These adapters are usually soft aluminum, so do not over-tighten them. The Ranger can hold about two to three average sized cans of coolant, plus one can of lubricant, from a completely empty state.
