Default air conditioning

Is there anyway to tell if the air condition has been converted to a R134 system

R134 uses larger fittings. If you have all stock components there should be adapters on the high and low pressure fittings.

Unless someone removed the adapter fittings after they charged it, then no way to know.

If there's no adapters on there and no tag or sticker then you really can't tell. Taking the adapters off after charging the system doesn't make sense but who knows.

X2 with John

Here's a pic from the web of an R-12 port about to be upgraded to an R-134 type with an adapter. Maybe you can see the difference.

With R-12 you screw on the service hose to the ports and the R-134 is a snap-on type.
Last time I tried to remove one of the adapters it bent the R-12 port - once you install the adapters - they are difficult to remove.

One possibility I can think of to fill the R-12 system with R-134 by using a set of service gauges.

Have any pics of your system?

Eric

It looks like you have a completely stock system. The upper hose looks like it may have been replaced but the bottom hose is original. The fittings are the original R12 fittings. Usually the hoses need to be replaced if you are going to changeover to R134. My guess is it still has R12 in it.
