When retrofitting a system from R12 to R 134a what is required to be done?

When retrofitting a system from R12 to R 134a what is required to be done?

Sanden Procedure for Conversion from R-12 to R134a Recover all R-12 refrigerant from the vehicle’s A/C system. Evacuate the A/C system for at least thirty (30) minutes to a vacuum of 29 in. Hg, using R-12 equipment, to remove as much R-12 as possible from the residue mineral oil. Remove all R-12 service equipment.

How do I convert my R12 to R134a?

How to Convert an R12 to the R134a System

  1. Discard any R12 refrigerant still in the system by taking your vehicle to a licensed air-conditioning professional.
  2. Open the engine compartment of your vehicle.
  3. Push the high side retrofit R134a fitting over the old fitting and use a wrench to tighten it.

Is it bad to mix R12 with R134?

The oils are different and not compatible and can cause an explosion. R134a is also a smaller molecule than r12 so if you HAD a small leak with r12 that you did not fix you have an even bigger leak now.

How to convert your car’s a / C system from R12 to R134a?

The A/C system in many older vehicles needs to be converted from R12 refrigerant to R134a refrigerant. This video shows you how to convert your vehicle’s A/C system from R12 to R134a using an IDQ Retrofit Kit. 1. Locate the low-side and high-side A/C service ports.

Is it possible to retrofit an R-12 a / C system?

The other approach to retrofit is the “quick and cheap” one. On many 1989 through 1993 vintage vehicles, R-12 A/C systems can be converted by simply recovering any refrigerant that is still in the system, adding POE oil (which is compatible with both types of refrigerant), and recharging to 85 to 90% capacity with R-134a.

What can happen if you put R134a in an R12 system?

R134a uses Polyalkylene Glycol (PAG) oil. One commonality both R134a and R12 share is that they are compatible with Polyol Ester Oil (POE). Finally, R134a is much smaller than R12 on the molecular level, and thus moves and behaves differently. What Can Happen if you Use R134a in an R12 System?

How do you change the refrigerant on an R12?

Start the engine and switch the air conditioning to highest setting. Put a thermometer in the center vent to measure the temperature as you add refrigerant. Connect the T-valve hose to the low side service port. Open the valve and allow the system to draw the refrigerant out of the can–you can feel the can get colder and lighter.

Can a car be reserviced with a R12 system?

GM recommends that vehicles with A/C systems designed for R12 be reserviced with R12 as long as the supply lasts. GM recognizes the need to retrofit A/C systems in the near future and is working out the details. GM states that under no circumstances should a retrofit be performed unless the customer has had the options explained to them.

When retrofitting a system from R12 to R-134a what is required to be done?

Can I put 134a in a R12 system?

To be able to use R134a in an R12 system, the R12 system needs to undergo a retrofitting so that it’s able to handle and process R134a refrigerant. This also means that some refrigerant conversion needs to be done in order to drop R134a into a R12 system.

Can you mix R12 with 134a?

The oils are different and not compatible and can cause an explosion. R134a is also a smaller molecule than r12 so if you HAD a small leak with r12 that you did not fix you have an even bigger leak now.

How to add refrigerant to a GMC c1500?

Recharging the freon in your AC system is an inexpensive and easy first step to restoring the cooling capacity of your A/C system. Most refrigerants include a leak sealer that will seal small leaks in addition to filling the R134a refrigerant. The A/C system in your C1500 consists of a compressor that is belt-driven, an evaporator and freon.

Can you add Freon to a Chevy c1500 suburban?

If there is a problem with your compressor or evaporator, adding freon will not restore cooling. How to add freon to your 1996 Chevrolet C1500 Suburban: hook up the can of refrigerant (likely r-134a) to the low pressure port. When your compressor kicks on, add freon to the correct pressure.

How do you add Freon to a Chevy Silverado?

How to add freon to your 2008 Chevrolet Silverado 1500: hook up the can of refrigerant (likely r-134a) to the low pressure port. When your compressor kicks on, add freon to the correct pressure. In addition to cooling, freon lubricates the compressor when it runs.

Can a GM R-12 be converted to 134A?

Contrary to popular belief, most cars originally equipped with R-12 can be converted to 134a and still keep you just as cool. Understanding the basic type of a/c systems GM used on their classics will help with you determine the best route for your project. This is a generic term for the earlier valve regulated systems for the early GM vehicles.
