Re: Tube & Fin Condenser on Roof?

I'm kinda late to this conversation, but why do you think a condenser is your biggest bottleneck? What are the pressures?

Re: Need help diagnosing ac problem

You are just low on charge, maybe a tiny leak. You should have about 72 psig at that temperature, your Focus ECM reads the ambient, reads the high side pressure, algorithm says you are so low on charge that there is only vapor in your system, it will not try to engage the clutch. Recover what exists...

Re: Need help diagnosing ac problem

I agree with B52, but it might also be too cold outside, what was the ambient air temperature when you got those pressures?

Re: Oil and gas mixed together?

How the oil exists depends on where it us in the system. In a liquid line it is in a sort of solution, a leak of liquid R134a is leaking also oil. In the discharge line it's an incredibly high velocity high turbulence mixture of liquid oil an vapor R134a, a leak of R134a also leaks oil. In the sucti...

Re: Daihatsu gino not blowing cold air

What makes you think there is a problem at all?

Some A/C systems are just weak performers by design, i.e. small compressor, low evaporator airflow.

Re: Compressed air to confirm leak

I can see the spot you are in, difficult to do things when you are not allowed to do things! I'll admit to having used compressed air a few times when in a tough bind. In general it's a sin and a last resort, the reason is that compressed air by it's nature contains a lot of water, and water in refr...

Re: Low side hose pinches when pulling a vacuum

Yeah, it used to be unthinkable that it could collapse. I replaced the condenser in my 2015 Silverado and peed my pants when I saw that hose

Re: Question about oil in new system

The oil qty is determined for a complete system, not a compressor only. Oil qty is also very conservative, the factory amount is usually more than necessary. There is nothing wrong with 7.1 oz, sounds just fine, it's a random shot in the dark, but I suppose a front only car is ballpark the same size...

Re: Low side hose pinches when pulling a vacuum

Sorry I didn't see this sooner. It's normal for newer GM suction hoses to collapse. Their new hoses are very soft, very good for reducing noise in the cabin, they collapse flat when you pull a vacuum.
