1986 Pontiac Fiero. What has to be done to be able to use R-134 refrigerant?


There are simple conversion kits that basically just replace the service ports to use the r-134 type hoses, but it is best to have a pro evacuate system and flush it, draw a vacuum, add correct oil and freon. If the system has been empty or dead a while, best to replace dryer and orifice tube or expansion valve as well.

Recharged AC, blew cold for 1 day then heard hiss near driver tire and now no cold air.


Whenever you add Freon,you are suppose to leak test first.Your compressor is good,you have a leak somewhere.A good place to take it to is Midas,they changed my freon over from the old stuff to the new R-134a,they leak test it first,that is rule 1 when adding freon.

What type of freon is in GMC trucks of 1987?


R12.... In 1994 R134a was required, but some changed earlier. Yours may have been converted. If the service ports are threaded it still has R12. Hope this helps.

if the low side is pulling into a vacuum it is more than likely an expansion valve. if you decide to fix the expansion valve i would go ahead and put a new receiver drier on and make sure you pull a good vacuum on the system and put the right amount of good clean freon in and i also add .5 to 1.0 ounces of a/c oil into the system.......good luck and i hope this info will help you............let me know how the repair works out and let fixya and me know how i did.............thanks........

99 Toyota Tacoma a/c reads high pressure on low pressure side


Does the compressor run?
Low side could be high without a running compressor.

A running compressor?
The expansion valve itself is about $50 and bolts in.
You will have to remove the 134a gas before installing a replacement expansion valve and vacuum the system before recharging.

Changed Compressor not blowing cold enough


If you tried using a refrigeration "sealing" product before changing out the compressor, you most likely do need to replace the expansion valve.

The valve "flutters" open/close/open/close/etc/etc when in operation. The purpose is to allow the compessor to build up enough pressure to change the freon to a gaseous state. Once you put in the sealer, the valve becomes plugged with the product and cannot seat completely. After this happens, you never get a full phase change because the pressure cannot build up enough. You will experience reduced cooling. Change the Exp. valve and you'll be set. In the future, it is not advisable to ever use the sealer products as this can cause damage to other system parts, and especially the recovery units at the shop.

if the line to the condenser ices back at that point, the system either has too much freon in it or not enough. its 134a refrigerant. if you add freon when its really hot outside, the pressures will be a little higher than normal. do not overcharge the system, since freon really doesn't go bad, it can get contaminated with moisture, and degrade the system. you need to have it dumped out and pulled into a vaccuum and see if it holds 30 inches of vaccuum. vaccuum boils out moisture in the system. check the drier/accumulator at the same time. if it has a sightglass on it , it will change color if there is moisture in the system.
