TRUE REACH IN MN TSSU 60-16 LOW SIDE IN NEGATIVE PRESSURE HUIGH SIDE AT 100PSI SYSTEM IS RESTRICTED WHERE IS EXPANSION VALVE?

This is a cap tube system. Try replacing filter, they often become clogged due to the oil used in the system. Cap tube can be clogged as well. could simply be low freon level. Evacuate the system and weigh in R-134A, amount is listed on model sticker. Also remember that when you attach gauges to the high side you are removing up to 2 oz., or more from circulation. Use a gauge with a short hose, like 6", on the high side. Be sure to bleed your low side hose with 134a before attaching to prevent moisture entering system, that also turns the oil to acid and deteriates the filter and clogs cap tube.

Cannot locate valve to add 134a refrigerant in a 2000 lincoln navigator

What your looking for is called a service port. On a 134a system there are two of them, located in the refrigerant lines. One port will be larger diameter than the other. The large one is the "high" side and the small one is the "low" side. refrigerent is added to the low side with the system running. You really should use a manifold gauge set to see what the pressures are before adding any refrigerant. If the system has too much, it is as bad as not enough.

Locating the High side and Low side AC gas ports

Easy. find the compressor. The larger hose attaching to the compressor is the "suction" side. This is where you install the refrigerant.

The smaller hose, whether rubber or metal as it travels to the passenger compartment, is the high pressure side.

After installing refrigerant and as the compressor is running, the larger hose will feel cool and the pressure side will feel hot.

Have 134a refrigerant and shop where I bought it said owners manual will have the how to instructions. Unfortunately it doesn't. I see on the line there is a stem to screw the hose into but want to make...

No,you won't find it in the owner's manual. It charges through the low pressure side,which is the larger of the 2 available ports. You can't hook it up wrong. I suggest you buy a Hayne's manual for the truck. It has 90% of any answer you might need. A/C can be tricky to fix for the novice. If charging doesn't work,take it to the shop.

95 Deville - Low Refridgerant/AC Comp. off

To diagnose problems, an A/C manifold gauge set is needed to read high and low side pressure readings. Avoid adding refrigerant with a simple charging kit like the ones sold at parts stores. Don’t add any stop leak, this can cause problems in the compressor, expansion valve or condenser.
Keep in mind that using an A/C gauge set and seeing BOTH high and low side readings can help in diagnosing the problem when you know what to look for. First, on a 134A system the high and low side service ports are different sizes. AC gauge sets have color coded hoses, the blue color coded hose has a connection that fits on the low side service port and the red hose has a connection that will only fit onto the high side. The yellow hose won’t hook up to anything if just checking the readings; it can be used to connect to a vacuum pump or attached to a refrigerant can or tank.

Normal readings on high and low side with AC OFF (static pressure) - Depends on outside temperature, but normally is between 80-105 PSI
Normal low side reading with AC on high speed and MAX & engine at 800-1000 RPM’s - Ranges from 25-35 PSI - Note that on many Chrysler products a normal reading on the low side may be 15-25 PSI
Normal high side reading ranges from 200-350 PSI

Don’t assume that if adding little Freon is good that adding a lot is better! Overcharging just a little can decrease the performance of the system and possibly damage the compressor.

Both low and high side readings are lower than normal, this indicates a cars AC system is low on refrigerant and is under-charged.
If both low and high side readings are too high, this indicates an overcharged system - too much refrigerant. This also can indicate that the condenser fan is not working, is too slow or the car is overheating and heat is transferring from the radiator to the condenser.

Good luck and hope this helps, keep me posted be glad to answer any question you may have. And yes the A/C system on your car uses R143a and there is a A/C pressure switch along the low pressure line or on the accumulator, it looks like a oil pressure sensor with a two wire lead cliped on it.

Want to know operating pressures on a 134a refrigerator low and high

Maximum efficiency is achieved when there is the greatest difference between high side and low side provided the low side stays under 30 psi or so. The low side pressures must stay low enough to cause the refrigerant to change states in the evaporator. If you see frost on the compressor suction line, there's too much refrigerant, and you'll overload the compressor. The correct approach, if you have the equipment and it sounds like you must have a gauge set but you need recovery to do this right, is to evacuate the sealed system, (a tight system will hold a vacuum overnight, but an hour is a good test if you suspect any leaks) and refill with the exact amount of refrigerant (by weight) as indicated on the ID tag.. Any system that will not perform when filled to that specification has either a bad valve in the compressor, or a restriction caused by contamination. Contamination is usually from moisture (humidity) introduced into the system by improper servicing, but is usually relieved if the system is under vacuum long enough to boil out the moisture. If the compressor is the culprit, it's usually game-over.

Operating pressures for 134A refrigerant system

I would go for 40 on the suction and 150 discharge, or divide the locked rotor current by 6 and charge so the current is 1/6 of the locked rotor current of the compressor, or by temperature/pressure relation 110* discharge and 35* suction, or get the suction line sweating. The best way is to remove all the refrigerant and then weigh the refrigerant the system is designed for on these critical charge appliances.

Some of this TRUE don't have service valves, but you can put a tapping valve (A1) in the appendix (small piece of pipe comming out of the compresor and seal on the other end).To check the pressure you need to know what type of refrigerant is in the system .If is 134a the low side should be about 24psi and the high around 160 it could vary depends how hot is inside the place and the fridge but not much more than 200.If you working with R22 pressures be around 60 low and 250 high side.

Good day,
The low side (suction pressure) is pretty nominal at 2 to 4 lbs.
The high side should range from 120 to about 14 lbs. depending on load and ambient temperature.
This would be after 15 minutes running time. Doors closed. Rear panel on as well as can be attached with gauge hoses protruding.

**** boy. 72 psi on the low side? It ain't an air conditioner. The low side should be never over 5 PSI. The whole system holds only arounf 4 ounces. What were ya thankin? LOL WOW you will be lucky if the reed valves ain't blown in the new compressor. Go ahead and evacuate the system. Pull that ****** down to as close to negative 30 as you can and then shut her down. Just crack open the freon a hair and let it SLOWL:Y build to no more than 5PSI on the low side.
