Its exact location can vary depending on the vehicle’s make and model, but you can typically find the orifice tube between the condenser and the evaporator on most vehicles.

Charging a A/C system by subcooling. Determine your target subcooling. This is usually displayed on the back of the nameplate, located on your condensing unit. If not, 10-15 degrees F will get you ballpark range. With the unit running, connect your high side refrigerant gauge, to the liquid line port, or fitting.I decided to upgrade to R12 in my 98 explorer. I removed the R134a with our 134 machine, then filled with R12. Normally when doing a 12 to 134 conversion you use only 80% of the old amount of freon, so a 1 lb R12 system gets refilled with .8 LB of R134.

Jan 15, 2016 · The expansion valve (orifice tube) is a component that is used in your vehicle’s air conditioning system. What it does is regulate the pressure of the A/C refrigerant as it enters into your car's evaporator. It's in this tube where the liquid refrigerant turns into a gas thanks to the pressure that converts it. The "Electronic Variable Orifice" (EVO) steering system was introduced by General Motors. The vehicle's computer monitored vehicle speed and steering wheel action to activate and deactivate a solenoid on the steering pump that controlled fluid flow to the steering gear. At slow speeds the EVO solenoid is fully open making the steering easier.Restricted or plugged orifice tube can also cause low pressure on an orifice tube system. Restriction in the low side of the system. For example, a restricted orifice tube will cause the compressor to suck, but the restriction/clog in the orifice tube prevents the full flow of refrigerant, causing evaporator starvation.This HVAC Training Video is about Thermostatic Expansion Valves TXV's vs Pistons.
