Re: R134 Can Side Tap Advantage?

Rarely do I use the small cans of refrigerant. But whenever I have in the past, I worried about the can-top valve detaching suddenly and the can going airborne like a rocket. Never happened to me, but I have heard stories about it. My tool collection includes the older piercing valves, the newer val...

Re: 1995 Buick Roadmaster - Poor Cooling - Pressures

I don't have any way to reclaim the system. I don't have an RRR machine, either. But a local tire store close by does. So I go there whenever I need to recover refrigerant. It takes only a few minutes, they're happy to do it for me, and they gain some "free" refrigerant, which they can re...

Re: 2002 Ford Taurus low and high side high pressure

I think we are gonna have to dissect this one step at a time, and first we need to know how you did the sealing. I could be mistaken, but I believe the OP meant that he closed both handwheels on the Manifold Gauge Set for 1-1/2 hours to see whether the vacuum would hold, which apparently it did. Hi...

Re: 2002 Ford Taurus low and high side high pressure

Is your Manifold Gauge Set hooked up correctly while charging--that is, low-side handwheel fully open, high-side handwheel fully closed, both adapter thumbwheels fully open (turned clockwise until they stop); yellow hose connected to the refrigerant source, and refrigerant-source valve fully open?

Re: Source for this GM ambient temp sensor

I haven't seen that sensor in decades, either. Have you tried asking a GM dealership to look it up for you in their old parts books and checking availability? Alternatively, can you repair the one you have by soldering the broken tab back on?

Re: 2006 530i bmw

I wonder how the shop knew the system was overcharged just by checking the pressures. They themselves recovered and recharged it, ostensibly to specs. So where did the alleged overcharge come from? (Rhetorical question.)

In any event, let us know what the BMW dealership says.

Re: 2006 530i bmw

Although I don't recall the OP mentioning recovering/weighing the refrigerant, evacuating/recharging, or posting any pressures, it seems to me that the high side might not be building enough pressure to turn-on the fan, as mentioned earlier. Problem could be a low charge, a faulty control valve, a w...

Re: 1st Post Need Help Honda Fit A/C Issue

Couple of thoughts: Fix the leaks first. Sounds like it could be a low-charge condition caused by the leaks, as mentioned, but also just a tired little scroll compressor (which is what I believe it has) after around 12 years despite the low mileage. The specs that I have call for 16 ounces of R-134a...

Re: 2002 Pontiac Ram Air Trans Am ac is not cooling properly

John, I'm understanding that the different color control valves don't really translate into cooler temperatures (more stroke), right? It would just be a trial and error type of thing. The different color control valves might or might not translate into more stroke and cooler temperatures. I don't h...
