Thinking of changing my compressor.

 

Are there 2 types?

 

My Z is a Jap 91 TT

Any advice welcome.

as ur pre 94 ur system will probably be full of R12 which is a planet killing gas u have to replace the full system and get a nice friendlier gas or just live with what u've got as finding an aircon system from a breaker aint the easiest.

 

if ur system just needs regassing the r12 oil molecules need to be removed from the system and then it can be regassed with r134 or whatever the equivilent is now its a specialised job.

I have a cylinder of R12 which you are welcome to, find a friendly Aircon man and job done,

Just to clarify, the old R12 refridgerant gas was phased out under governmental pressure for environmental reasons and according to where and what you read its impact on ozone depletion etc. is the main reason, that said 134a is just the best of the worst rather than a perfect solution..... politics really.

 

So in back in the real non political world there are some real differences as far as system impact is concerned.

 

Before going down the route of changing the entire as system, get hold of some port converters off e-bay and fit them to the pipework ( easy ) go along to the ac man and say hey can you do a check for leaks using a cheap inert gas.

 

Once checked and vacced down ask them to add some pag oil to keep the compressor happy and add then a volume weight of R134a that is slightly less than the volume weight of R12 on the label at the front of the car.

 

Then when complete and all running with nice cool ac, be happy it cost you just £50 to £80 rather than hundreds to change the system, yes it is a compromise and maybe only 90% as good as a newer type system.
