How many pounds of freon does it takes to full the A/C system on a Mack truck CH 613_2004
Why would you want to even consider doing this? R12 is no longer in production and as such it cost almost 4 times as much as R134. But to answer your question, use R12 in a R134 system and you will destroy the compressor as the oil is not compatible with R134 oil.
how much r134 does a ford 500 take
The 1992 GMC Suburban came from the factory with R12 not R134. Unless it is has been converted to use R134 you cannot simply add R134. If it has been converted you need to have the leak fixed before adding anything. It is illegal to add refrigerant to any system without first repairing the leak. How much it will hold depends on how much leaked out.
Enough to recharge the system after the leak is repaired and no more.
If you mix r12 with r134 air conditioning system, it will cause a high pressure in your airconditioning system and eventually damage the compressor and the evaporator. R12 is only for r12 aircon and something with r134, it can't be mix.
NO ! and Why?
1.53 lbs of R134
Yes, That is a must do.
R12 It is not produced anymore. Have to covert to R134.
Yes. In fact, it's the only refrigerant you can use.
Your best choice would be to check into what local shops in your area specialize in air condition service.Being your truck probably still runs the old r12 the system may need to be converted to the new r134.If the condensor or compressor are the issue,or the air condition is not cold or even turning on is the result of a leak,blockage in most cases.I would strongly suggest asking around for a reputible shop that does AC service and will service and do diagnostic work and recommend having the system flushed and switched to the r134 which is compatible with your vehicles ac system!I could elaborate more it is just to much information to try and explain all the specifics.OK and note I have converted a older r12 system to the newer r134 and not to expensive to do,however I did not have to change any of the systems parts.Keep that in mind.
