I think it is time for a new gauge set. The gauges still work great, but the hoses are giving me more problems. About 10 years old, and a cheap set to begin with, probably just time to start over. I use it 2-3 times per year. Only filling a system average of once a year. My vehicles are slowly getti...

I put exactly 3.1lbs in. As specified. On a side note, no oil would drain from the old compressor, as in not a single drop even turning the pulley. However, I drained about 8 oz out of the old receiver/dryer. Total system spec including compressor is 11oz. There was dye in the system. I suspect they...

Here are the fans mounted. And the rear evap before I cleaned it.

Finished putting everything together, even got the fans mounted, but no wiring done yet. I have less than two pounds of r-134a left and the system takes 3.1, so not enough for a second try. Luckily it works great. It was only 70 degrees in the shop, but after I charged it, I had cold air constantly ...

Started taking it apart today because the parts showed up early. Condenser was full of bugs again, but 95% of them fell off with a light brushing this time. Anyway, I can't find the orifice tube. I thought it should be in the evap inlet, alldata shows the evap inlet for a location, but there is noth...

I ordered parts, compressor, rear expansion valve, dryer, ford orifice tube, and fans. I decided to jump to the end and ordered a pair of the fans for a tahoe. We've only put about 300 miles on it since I did all the maintenance, but the condenser is filled with bugs again. The van does not have a h...

Hard to find ones that specify size.
These were the best match I could find, one variable and one fixed.

ACDELCO 1550120 GM red variable orifice tube

MOTORCRAFT YG346 Ford Red Fixed 0.062" tube

What would be my best choice?

I will need to look harder for the high side fitting. Hopefully there is one hiding, maybe down near the compressor. I used a cheaper gauge set, that has been working for me for more than 5 years. My r-134a tank has less than 10lbs of refrigerant left in it, but should be enough to recharge the van....

Thank you. Do you have part number for the Ford orifice tube? Would that single size work better than the severe (hot weather) variable tube? Other than that, the van is very clean, inside and out. I flushed the cooling system and replaced the thermostat, and while I had the fan out, I removed the g...

I just purchased a 2017 GMC Savana for my wife to use as her dog training vehicle. A/C is very important to her, especially at an idle, such as sitting in a parking lot with the dogs in the van. She has a temp warning device that connects to her phone in case of a failure, but we haven't gotten far ...
