How can I determine whether or not my 1992 Honda Accord has been retrofitted for 134 refrigerant.


R12 fittings are threaded on the outside and are smaller than R134a fittings which have no threads on the outside.

What is the number for the airconditioner R-12 or R-134 for cadilac eldorado 1992 cp?


It's probably r12. You can tell by the fittings. R12 will have threads on the outsides of the service fittings. R134 uses a quick connect style service fitting.

What type ac fluid used r-12 or r-134


Check the schrader valves where you charge the A/C system if it has threads on it like you can screw on the A/C manifold gauges then its R-12 if it has the type that couple on and no threads then its R-134 but make sure no one has screwed on some 134 fittings on them. Normally on the outside there it should tell you what type freon that vehicle should take you need to look around under the hood at the labels and see if you cant locate it.

What type of freon does a 1993 chevy g20 van use?


I think 1995 was the change over year to R-134a. Your car should have R-12. If it has small threaded acme fittings its R-12. The R-134 fittings are different sizes and have snap lock fittings similar to an air hose.

Need to know if my 1993 ford club wagon is r-12 or r-134 is there any way to tell from fill ports? the r-134 CANISTERS FIT ON THE LOWSIDE, ARE THE R-12's a different size?


If it is a quick connect fitting, it is R-134a
The low(charge) side fitting is: 13mm
The high side fitting is: 16mm

If it is a threaded fitting with threads on the outside, then it is the older R-12 refrigerant and can only be serviced by a licensed air conditioning service.

The low(charge) side is 7/16" threads
The high side is 3/8" threads

When servicing your air conditioner it is best if you have gauges, but it can be done without, just be careful.

Assuming the air works, but just not putting out that much cool air, then 1 or 2 cans of refrigerant won't hurt.

If there is no pressure/refrigerant in the system at all then it is usually a sign of a leak and should be taken to a pro because you may need to replace the receiver/dryer and have the leak fixed. The system needs to be evacuated for maximum efficiency if there was a leak or if hte system has been opened.

Adding too much refrigerant can be catastrophic as the high side pressures can reach 200-300psi on a hot day. So if you happen to have a low side gauge, and it reads somewhere between 35-45 with the Ac operating, you are golden.(tire gauge won't work)

Don't be surprised if the compressor doesn't kick on right away. Some vehicles are equipped with a pressure switch to keep from damaging the compressor if it runs low. Usually after adding one can, it is enough to engage the compressor.

Hope this helps.

1995 olds 6cyl r-12 or 134 a/c coolant ?


They could be either way in 95. Look at the fittings where you charge the A/C. if they are threaded on the outside it is a R-12 system. If they are round and not threaded then it is a 134-A system. Good Luck

HI, To know exactly the tipe of refrigerant you have.
You need a machine to recover and identified.

But if you want to know the tipe of fitting you have
Only are 2 on cars.
R-12 the fitting look like bolt with thread outside.
the service hose go in threaded. to connect
R-134 they are fitting called quick connector.
Because you put making a litle pressure.on it to connect.
They don't show thread.

If your car is made after the six month of 1993. is R-134
if yor car is made before the six month of 1993 is R-12
