Can I use it to vacuum a/c system on 1990 crown victoria (it has R12 NOT R134) ? or it doesn't fit old cars?

Yes, you will need an older set of gauges with the hoses that fit your car. The yellow hose will screw right on the pump.

You will need to get your hands on the proper vacuum line with the connections for your car's a/c vacuum port on one end and for the pump fitting on the other end as the pump does not come with lines/hoses.

Yes, it can, and that is how I ended up with a broken unit. It is supposed to work, but when I applied vacuum, the gauge topped out and has not moved since. (high side). I was able to pull a vacuum and do the work. I think I got a bad unit. Still, all together, it cost less to buy this and have it go bad than to have the A/C work done in the first place.

Yes - unless they are pretty old. You can google to find out what type refrigerant your can takes. My car is a 1998 Nissan, and it works on that car. - Surprised me.

If your question is, "Will these hoses work on R134 Automotive A/C", The answer is NO not without an adaptor set to make the connection to the car but the will fit to any standard 1/4" flair Manifold Gauge set for all types of refrigerants and oils. Hope this helps!

I'm sure it will, if you have the connection. I use it on automotive a/c units. it does a real nice job pulling vacuum.

Yes. I do big systems. Over 10 ton split system with this manifold. Cut down on vacuum time. It work well on a mini split system I install but I had a double condenser with five air handlers system. I did use the adaptor part no. 19175 yellow jacket.

You have a central vacuum system, as your number indicates, therefore I doubt it will work. However my research was limited.

It will take the same adapter that goes on an older car that has the R 12 freon. You should be able to get them at any auto parts store. It will just thread onto the fitting and the R 134 hose will snap right on. Just get the fitting for the low side charge port.

This can isn't a fit for the '04 R6. With some mods it might can work though.

Bill as long as your motor has a vacuum line coming off the cylinder head it will work fine . The hose is located in the lower portion on the passenger side . Some motors have them some don't . If you need anymore help just ask. Rob Rossi

This will not work on that system unless it has been converted to R-134. Your car came with R-12 from the factory.

Yes, It should work to convert your R12 service ports to R134A type ports! However R12 systems are not compatible with R134A refrigerant!! Your R12 system must be completely purged /flushed and new seals installed throughout the system. R12 refrigerant is very,very expensive and difficult to find as it is environmentally unsafe when released into the atmosphere!!

No. Domestic and automotive air conditioning systems are not compatible, unless you have an older model car that used R-12 refrigerant. Paul

I purchased adapter for my old vacum pump which was a 5/16 for R12 and now can use for the R134 which is 1/2 which saved me from buying a new vacum pump.

Yes but you need too buy the convert adapter and clean or recovery the old R12 and fill whith R134a

Unfortunately this manifold is only for HVAC systems and not automobile 134a / r12 refrigerant gas. You have to purchase Uniweld Model QAL5SM or QAL5SMA in order to use with R134a.

Yes it will fit , However, if you are converting to R-134, this compressor is not designed for the higher viscosity of R-134 and will fail in two or three years. I had to replace my compressor in my 1980 corvette three times in the past 8 years running R-134 and finally got wise and updated with an aftermarket pump and receiver dryer designed for R-134, Have not had a problem since.
