Re: 240z with RB25DET engine - 3x workshops said it cannot be done

No, the Condenser goes in the front of the car, preferably in front of any intercooler. It needs airflow to dump the heat collected from the car's interior. The heat exchanger that goes inside the cabin is the Evaporator. Refrigeration lines can be made up by any competent hose shop. The basic compo...

Re: 240z with RB25DET engine - 3x workshops said it cannot be done

The 240Z was popular enough that there were aftermarket kits to add A/C built & sold. There were also factory A/C cars in 1973 I believe. Contact the site sponsor AC Kits and ask if the aftermarket kits are still available. AC Kits was the originator of many aftermarket kits back in those years....

Re: Live evap but no air blowing, parallel evaps in coach HVAC

Too much oil can be as big a problem as too little.

Multiple evaporators are done on millions of SUV's - and just as may mini-split HVAC units in homes.

Look here for a good "too much oil" tale

Re: Quality can tap?

Side can taps ROCK. My only choice for stuff in cans. https://www.ackits.com/side-mount-can-tap-for-r-134-a-cans-17241?search=side%20can%20tap Reliable, easy to use. Works on all of the standard size cans. Ever drop a nearly full can of brake cleaner, and snap off the valve stem? Yep, works for that...

Re: DIY Vacuum Pump Showing Moisture Removal.

Found it. I lost the original photo with a drive failure years ago. Damn, over 15 years ago I posted that.

Re: DIY Vacuum Pump Showing Moisture Removal.

Somewhere on the old site I posted a picture of an FS6 that would pump down to 800 microns on the suction side - with the discharge open to atmosphere. I was only turning that FS6 about 250 rpm too. I would trust the York if it was in good shape. But a tired hermetic from a discarded refrigerator is...

Re: Leaking aeroquip fittings??

Contact Aeroquip and find out what the annual permissible leak rate is for that fitting. Everything leaks a little. You are losing a pound in 3 years across 8 fittings and several feet of hose. Commercial stationary comfort refrigeration is allowed to leak 10% of the total charge per year by the EPA...

Re: Finding A Leak In A New System

An ounce or two of refrigerant should give you plenty of pressure for a leak test. No need to fully charge the system.

Manifold valve leaks and service hose / connection leaks happen occasionally. More common on rental / loaner units...
