My 93 Dodge Dakota uses the old type of freon for the AC, BUT?

Question

Someone told me today to change it to the newer ozone friendly freon all you have to do is let all the old freon out and put the new stuff in, and it also requires a different type of connector so that the new freon can be added.

Is this true...That sounds just too simple.

Answer 1

First of all, your Dodge is running on R-12. Second, you have to be certified to even get the freon (r-134a) to replace the freon.



To do the job right, you need special equipment (gauges, vacuum pump, etc.) to take out all of the freon and any condensation in your system. Next, you have to convert the original system to compensate for r-134a. This requires replacing the A/C compressor, the evaporator, and some lines. Then you have to put in the right amount of freon in the correct side of the system.



Simply put, you should have a trained, certified mechanic do the work. It's going to be expensive to convert your system to R-134a. Some shops still have a limited supply of R-12 available. Maybe all you need is to replace what is wrong with your original system and have them refill with r-12.

Answer 2

To do the job right, you need to have the R-12 removed. You them need to remove the compressor, and drain the oil. Add the correct amount of R-134a oil, and reinstall the compressor!

Install the adapter fittings on the high and low pressure ports. Using a set of manifold gauges and a vacuum pump, create a vacuum in the system. Install the proper amount of R-134a and you should be done!

Answer 3

I HAD IT DONE ON MY CAR!!!!



cost me about $50 and had it done profesionally



you can buy the retro-fit kit from autozone along with the ester oil that is needed



i cant tell you how to do it but it is easy and can be done and you dont need to replace any hoses or anything....just oil and freon and screw on the adapters

Answer 4

Someone told you wrong.



R-12 and R-134a are not compatible and are of different molecular makeup, requiring at minimum replacing the hoses. Most often the compressor also needs replaced and the oil for the two is different.



It is a big project and expensive as well.

Answer 5

you do have to remove all the old freon for the best results ,and only a shop will have the right equipment to do this with,they also have the pressure gages to work with,and this needs a certain amount of pressure to work right,so id let a good shop do this,you,ll get better cooling from it,if its done right,good luck on it.

Answer 6

Dude, I'm sure one these people is right. Take it to a Mechanic that does AC work. Hel Jiffy Lube might work. they will tell you what you need most likely for free. If you think you can do yourself after a mechanic tells you what you need to do, then go for it. But I would leave it to a professional.

Answer 7

It IS too good to be true. You have to change a lot more than a connector, and usually only a qualified mechanic is capable of doing it correctly.

Answer 8

You can buy kits to switch from R12 to R134. It's really easy. Go to your local auto parts store and they'll hook you up.

Answer 9

blower motor resistor is unpluged. it is located on passenger side of fierwall. 5 wire plug. that should take care of blower. good luck God bless.

Answer 10

You hasve to have most of the system changed since the connectors can't be replaced by them selves it has to be lines and other parts.

Answer 11

u have to replace the whole a/c system to run on the new stuff. the conversion isnt all too expensive

Answer 12

fire4511 got it all, except you should change the dryer also.
