Can not find line to charge ac on 2008 ford f 250 ?


Look at the compressor on hose assy, low side
I\'m guessing-- but if you got a TXV-- it will be after it on low side
If you got an orifice valve-- it will be before the evaporator
Very important-- IF your NOT using refrigerant gauge set & your
using the wal mart crap with the hose & gauge ,you have no way
to vent out the air in the hose & under NO Conditions do you
put in refrigerant with any sealer.
Any air you let in that system will ruin it in time & reduce the
efficiency your trying to get back
If you have to add,you have a leak to fix
I would leak test & make the proper repair

CAUTION The refrigerant used in A/C systems is an extremely cold substance. When exposed to air, it will instantly freeze any surface it comes in contact with, including your eyes. It is imperative to use eye and skin protection when working on A/C systems.


SAFETY PRECAUTIONS

R-12 refrigerant is a chlorofluorocarbon which, when released into the atmosphere, contributes to the depletion of the ozone layer. Ozone filters out harmful radiation from the sun. Consult the laws in your area before servicing the air conditioning system. In some states it is illegal to perform repairs involving refrigerant unless the work is done by a certified technician. It is also likely that you will not be able to purchase R-12 without proof that you are properly trained and certified to work on A/C systems.


The refrigerant used in A/C systems is an extremely cold substance. When exposed to air, it will instantly freeze any surface it comes in contact with, including your eyes. Although normally non-toxic, refrigerant gas becomes highly poisonous in the presence of an open flame. One good whiff of the vapor formed by refrigerant can be fatal. Keep all forms of fire (including cigarettes) well clear of the air conditioning system. It has been established that the chemicals in R-12 (used on 1984-1993 models) contribute to the damage occurring in the upper atmosphere. 1994 models use ozone-friendly R-134a refrigerant. Under no circumstances should R-12 be allowed to enter an R-134a system, or vice versa. Never mix parts between the systems as they are not compatible. This includes O-rings and refrigerant oil. Servicing (recovery, evacuation and charging) of the A/C system, should be left to a professional certified mechanic with the proper equipment and related training.


SYSTEM INSPECTION

A lot of A/C problems can be avoided by running the air conditioner at least once a week, regardless of the season. Simply let the system run for at least 5 minutes a week (even in the winter), and you'll keep the internal parts lubricated as well as preventing the hoses from hardening.
Checking For A/C Oil Leaks
Refrigerant leaks show up only as oily areas on the various components because the compressor oil is transported around the entire system along with the refrigerant. Look for oily spots on all the hoses and lines (especially on the hose and tube connections). If there are oily deposits, the system may have a leak, and you should have it checked by a qualified mechanic.
Check the A/C Compressor Belt
The compressor drive belt should be checked frequently for tension and condition. Refer to the information in this section on "Belts''.
Keep the A/C Condenser Clear
The condenser is mounted in front of the radiator (and is often mistaken for the radiator). It serves to remove heat from the air conditioning system and to cool the refrigerant. Proper air flow through the condenser is critical to the operation of the system.
Periodically inspect the front of the condenser for bent fins or foreign material (dirt, bugs, leaves, etc.). If any cooling fins are bent, straighten them carefully with needle nose pliers. You can remove any debris with a stiff bristle brush or hose.


REFRIGERANT LEVEL CHECKS

See Figures 1 and 2
Factory installed Toyota air conditioners have a sight glass for checking the refrigerant charge. The sight glass is on top of the receiver/drier which is located in the front of the engine compartment, on the right or left side of the condenser assembly (some models are in front of the condenser/some are located on side of engine compartment).
If your car is equipped with an aftermarket air conditioner, the following system check may not apply. Contact the manufacturer of the unit for instructions on system checks.

  1. With the engine and the air conditioning system running, look for the flow of refrigerant through the sight glass. If the air conditioner is working properly, you'll be able to see a continuous flow of clear refrigerant through the sight glass, with perhaps an occasional bubble at very high temperatures.
  2. Cycle the air conditioner ON and OFF to make sure what you are seeing is refrigerant. Since the refrigerant is clear, it is possible to mistake a completely discharged system for one that is fully charged. Turn the system OFF and watch the sight glass. If there is refrigerant in the system, you'll see bubbles during the OFF cycle. If you observe no bubbles when the system is running and the air flow from the unit in the car is delivering cold air, everything is OK.
  3. If you observe bubbles in the sight glass while the system is operating, the system is low on refrigerant.
  4. Oil streaks in the sight glass are an indication of trouble. Most of the time, if you see oil in the sight glass, it will appear as series of streaks, although occasionally it may be a solid stream of oil. In either case, it means that part of the charge has been lost. This is almost always accompanied by a reduction in cold air output within the car.

GAUGE SETS

See Figure 3
Generally described, this tool is a set of two gauges, a manifold and three hoses. By connecting the proper hoses to the car's system, the gauges can be used to "see'' the air conditioning system at work. Do not use the gauge set as a means for discharging the system.

DISCHARGING, EVACUATING AND CHARGING

Discharging, evacuating and charging the air conditioning system must be performed by a properly trained and certified mechanic in a facility equipped with refrigerant recovery/recycling equipment that meets SAE standards

I am trying to put an AC recharge can into my car and can not locate the valve where the cans dispenser is to be connected to complete this...please help


Attach the end of the recharge hose to the low side pressure port on the passenger's side of the engine compartment, near the firewall. Look for the metal coolant lines and follow the lines to locate the low side pressure port. The port is usually covered by a plastic cap. Screw the discharge end of the recharge hose -- the end without the handle/valve -- to the pressure port.
  • Screw the valve end of the recharge hose onto the top of the can of refrigerant. Turn the handle clockwise to pierce the top of the can of refrigerant. Turn the handle counterclockwise to allow the refrigerant to flow into the hose.
  • Start the Cutlass. Turn on the air conditioning to the maximum setting.
  • Turn the can of refrigerant upside down and gently swirl the can. This moves the refrigerant from the can to the hose and into the air conditioning system.
  • Insert a thermometer into the interior of the center air vent and test the temperature of the air coming from the duct. It should be approximately 35 degrees colder than the ambient air temperature.
  • Add more coolant if necessary. If you are using 12-ounce cans, unscrew the first can and screw the hose onto the second can. Turn the handle clockwise to pierce the top of the can, then turn it counterclockwise to allow the refrigerant to flow into the hose. Do not add more than 24 ounces to the system. Take your Cutlass to a service center if you have added more than 24 ounces to the system and there is no difference in the temperature.
  • Turn off the engine of the Cutlass.
  • Turn the handle on the recharge hose clockwise to seal the can of refrigerant of it is not empty. If it is empty, unscrew the can from the hose. Unscrew the discharge end of the hose from the low side pressure port. Place the colored cap over the pressure port.

How to recharge recharge airconditioner


Hi, determine if your car uses R134 or R12 refrigerant. You will notice screw type connectors on the both the High Pressure Side and Low Pressure Side lines in models using R12 refrigerant. R134 compatible models have quick connect valves on both sides. Models made before 1995 may use the old R12 refrigerant. If this is the case, you must have your Chrysler's air conditioning system retrofitted to use R134 refrigerant. Mixing R12 and R134 refrigerants is dangerous and may cause damage to your vehicle. Check your air conditioning system pressure using an automotive air conditioning pressure gauge. Keep in mind that in order to get an accurate reading, the air conditioner has be turned on the coldest setting with maximum blowing power. Remove the Low Pressure Side port valve cap and set it aside. The location of the port varies, but it is usually in front of the engine block. Attach the refill hose to the port on the Low Pressure Side of the air conditioning system. The Low Pressure Side port is smaller the High Pressure Side port. Because the ports are different sizes, the refill kit hose should fit only on the Low Pressure Side port. Additionally, the High Pressure Side port will usually have a red cap or be marked with an H or the word High Allow the air conditioner to **** the refrigerant out of the can by slowly turning the valve on the refill kit hose. Pay attention to the way you hold the can. Most kits will have you hold the can upright when you recharge the air conditioning system. It may take as long as 10 minutes to empty a single can. Turn the valve to the off position and remove the refill hose from the port. Recap the port before closing the hood. Let the air conditioner stay on for at least 30 minutes. This allows the refrigerant to move throughout the entire system.
Take care

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.

Air condition not cooling. Indicator light flashes when air is on intermitantly.


Check the refrigerant charge of your system. If there's no pressure in the lines, the whole A/C system will shut-off. Check for leaks in the tubes, hoses, filter dryer, pressure switches, and compressor fittings. If the system has no charge and there's no visible leak from the items mentioned, the leak could be in the evaporator coil or condensing coil.

Would like to recharge my air conditioning on my 2001 nissian maxima that has 117,000 on it blows hot air when air conditioning is turned on.


You will need R134a, and a filler hose. Charge the system on the low pressure side, it should have a blue cap on the charge point.
Your filler hose will only fit the low pressure side, just in case the cap has been removed.

Air conditioning


The system refrigerant charge was most likely low but not empty, so you would get a burst of pressure and oil, the oil that lubricates the AC compressor circulates with the refrigerant. Does this make sense?

Recharging the a/c


Charging the A/C system is really simple. I have a '98, but don't know why a '97 would be much differrent. So, see if this works for you.

You will need a charging hose with a guage and two or three cans of refrigerent (R-134A). If your system is out of refrigerent you have a leak. So, make sure one of the cans you buy has marking dye in it so you can figure out where the leak is. Depending on how large a leak you have, it may take several weeks and months or just a few days. Most canned refrigerents have a sealing material that may plug the leak for an extended period of time or even permanently.

With the engine running and air conditioning on, disconnect the harness from the low pressure switch on the accumulator (left side of engine compartment).

Use a small wire to jump acoss the two contacts, the compressor clutch should engage and the compressor should start turning.

With the refrigerent can attached to the low side hose (blue connector), connect the hose to the low side port on the accumulator.

Open the valve on the charging hose. Refrigerent should start flowing. Shake can periodically refrigerent is drawn into system. Can will feel very cold and probably begin sweating as the refrigerent evaporates and is drawn into the accumulator.

There should be technical sticker under the hood to tell you how much refrigerent to charge system with. When it reaches the correct pressure 25 to 45 psi depending on ambient temperature, you are close to the correct charge, (most gauges you get at auto parts stores have a "blue zone" to indicate proper charge) close charging valve and disconnect the hose from accumulator. Though you can't tell exactly how much refrigerent you've put in, by knowing how much is in each can and how many cans you put in you will have a pretty good idea.

This will all go fine as long as you don't have a bad compressor or other sealed system problem.

Good Luck!
