Re: Sealant for NPT fittings

Here's what I said in another Forum on this board in case you missed it. I wouldn't use any kind of plumbing pipe dope for NPT or NPS fittings because of the risk of contaminating the system with incompatible substances. I wouldn't use plastic tape on the threads, either, because any remnants of the...

Re: How cool should be vehicle ac be running?

If it worked well for a week and then it didn't, I agree that your A/C system probably has a leak or leaks... someplace . The trick is to find it (them) by having the shop check every part--including the new components--using a "sniffer." Although buried deep inside the dash, checking the ...

I don't think it's actually connected. I believe the OP is just holding the fitting right above the port of the tee to show that it won't thread on. I agree, though, the picture looks confusing.

Re: gauges leak out freon after use

As said, the yellow hose fitting for R-134a should readily thread onto the 1/2" ACME port...unless your vacuum pump fitting is the left-hand-thread version that's designed only for R-1234yf. Both adapters look identical at first glance.

Re: Replacing my 03 CR-V system for a 2nd time and kinda messed up on charge

I'm trying to attach a photo of the old compressor. It didn't leave black death throughout the system. Just kinda let go all of a sudden. My son and I will be dissecting it soon. That's a pretty impressive compressor failure. Could be that something broke internally causing the case to rupture, exc...

Re: How cool should be vehicle ac be running?

What issues were you having with the compressor and evaporator?

Re: Replacing my 03 CR-V system for a 2nd time and kinda messed up on charge

New question. Do you absolutely suggest replacing the desiccant again? It was replaced with the new condenser and only had about 2 hours run. It's been under vacuum for the last 18 hours. Some air and moisture made their way into the system earlier. And since evacuation won't pull any moisture out ...

Re: 2006 530i bmw

I think this is probably a clutchless variable. Although the OEM Denso Compressor, Part Number 471-1542, for this vehicle is listed by multiple vendors as being sold "with clutch," on viewing the pictures closely, it does appear to have a control valve mounted in it. So I think you're cor...

Re: 2006 530i bmw

Another thought: Have you checked the gap between the clutch plates? BMW might be different, but on most vehicles, it's 0.020" or smaller as long as the clutch doesn't drag. As the ambient and engine-bay temperatures rise, the clutch windings might not generate enough magnetic power on a 15-yea...

For the 6-cylinder 3.0 Liter engine, the specs are 26 ounces net weight of R-134a and 5.1-5.7 fluid ounces of PAG-100.
