Re: 2020 Jeep Wrangler - Frozen Evap?

It dawned on me that this thing has a cabin air filter. My tuck doesn't have one so I completely forgot about the darn thing. Anyway, I pulled it out and it was pretty rough. I have no doubt that it was restricting at least some airflow. I hooked up the gauges again after taking it out and the high ...

2020 Jeep Wrangler - Frozen Evap?

Ran into an issue with the wifey's ride today. Coming home today she called and said the the fan wasn't working right. She said with the fan on high it was barely blowing like it was on low. I suspect that the evaporator may have frozen over. When I got home, I took it for a quick drive and it was ...

Re: 2008 Altima Not Cooling


Drive the car on a hot day and report back


It got into the low 90's today (like 91°-92°) and it cooled like a champ. So far very pleased with the results. Assuming there isn't some microscopic leak that isn't showing itself yet, I think this one is licked.

Thank you guys for all of your help ...

Re: 2008 Altima Not Cooling


Why did you replace the comp? Did the previous one fail? This is important.

Drive the car on a hot day and report back

It didn't crater, but there were large amounts of oil and dye all over the bottom of the compressor. I could add refrigerant and it would cool, but not long. I posted the ...

Re: 2008 Altima Not Cooling

I didn’t do anything with oil. The compressor came with the proper amount of oil already in it.

Re: 2008 Altima Not Cooling

Well, shows what know...or don’t know. I thought those pressures were supposed to be higher.

The compressor came with the oil pre-filled from the manufacturer. The system calls for 18oz. of refrigerant according to what JohnHere posted. I may have slightly misjudged how much I put in. I’m probably ...

Re: 2008 Altima Not Cooling

Okay, system charged. The ambient temp when I started was about 81°, but has now dropped to about 78°-79°. I added maybe a little over 1.5 cans of refrigerant using provided directions in this thread. Best reading at center vent @1500 RPM was 41°/42°. Pressures don't seem right. Pressures as follows ...

Re: 2008 Altima Not Cooling


Yes, sounds about right, good job.
Be careful when you switch your yellow hose from vac to charge that you do not introduce any air!!
Be sure you bleed all your hoses of air.
You are probably using cans even tho that is not the preferred way.
For the first can, turn it upside down and thus rapidly ...

Re: 2008 Altima Not Cooling

IMG_6383.jpg And we have liftoff...

Low and high port schraeder valves replaced, fresh oil in the pump and back under vacuum. Went to 28 inHg almost immediately. I actually tapped on the gauge a couple of times and it went to 30 inHG. The plan is to let it vacuum for an hour or so, then let it sit ...
