There is a dye you can put in the system that glows in a black light. Put it in and run the system. Check with a black light and the leak will show eventually.
Saw it used on Wheelers Dealers TV show from

When you guys pull a vacuum on the ac system, how long is needed to see the system seems OK? My neighbor has all that stuff

O.K. , I'll try to not let this message be the size of a 'phone book , it would be if i covered everything this week =8-^ .
It turns out the Uro fan works O.K. (it vibrates at speed) , there's another as of yet undiscovered fault.....
Anyone know where the fan relay is located ? .
Anyway , the horrific noise my Coupe started making the other day turned out to be my brandy new SANDEN AC compressor grinding itself to junk because the guy who install it muffed the job on several levels ~ he left things loose so multiple fasteners fall off as i was driving , he didn't tighten the hose connection to the back of the compressor so all the Freon leaked out and his screwed up the wiring so the compressor was running constantly even in the non AC " EC " mode , the screwed up wiring also meant the high/low pressure safety switch was BY PASSED so after the Freon was gone , the oil dribbled out bit by bit and the poor compressor ground up due to simple lack of oil.
He also damaged the body a bit and didn't install the new Condensor properly so it was rubbing on the body and one bracket was detached.....
I have much work to do , I am now looking at buying an AC vacuum pump to properly evacuate the system , maybe even a pressure pump to better test it before charging .
There's a whole lot more bad news , let your imagination run wild .
On the positive side of things , I decided whilst I had to car up in the air I might as well replace the aging American made fractional V-Belts with proper Metric news ones , of course I got a mixed pair of alternator belts , one made in Germany , t'other made in CHINA ~ guess how well they're ' matched ' .
On they went after a very small amount of cleaning , this is the good news : in spite of the recent fuel leaks I've had , I am very pleased to see almost ZERO engine oil leaks under neath the car ! this is a happy thing as I've been replacing gaskets and grommets etc. for a while now .
The intake tract had very little oil in it , only on the bottom part , not lightly coated as is common .
I decided to replace the engine shock absorber mounts , the one below the IP was disintegrating (I have a 'photo but my computer suddenly doesn't see it) , The Classic Center now has the kits very affordably and this includes the hardware , nice as the over sized 6 MM hole flat washersd make dandy problem solvers .
Still no HAVC =8-( , lots more other works to do .
