guidance needed for HVAC gauges/frigi-quiet
I am going to redo my A/C system
I would like some guidance on what manifold gauge set to buy I don't want to spend more than I have to but want what is good for a diy guy I am going to put in a new dryer temp switch dryer hose expansion valve evaporator temp switch (ETR) pressure switch heat temp sensor water temp switch O-ring kit am I missing anything (don't want to do compressor if I don't have too or evap. or condenser you know the big money stuff unless really needed so I will do all this stuff first) maybe a kilma I'll jump 5 to 7 pin I'm putting freeze 12 in ( how many cans do I need?) I can only find the BG frigi-quiet II at diesel giant ($42 seems a little high but...) and nowhere else? I am going to replace my dash (after A/C stuff) because P.O. dog ate some of it!! What do I need to do when I am in there ...what are those pods called and how many do I need or how do you test them? Any help is good help any progress is good progress as I always say! |

Go to the BG website and contact them. I did that and paid $11 for the Frigiquite oil.

I am using Freeze 12 as well. I wanted R-12, but the Freeze12 has been working well, and is now on it's 4th summer season.
I replaced the compressor with a new Hancock Industries one. It does have the stepped ports though. I also had the hose under the engine rebuilt, due to a PO splice and rupture, flushed the system w/Methanol, installed a new drier, expansion valve, temp switch for the aux fan, and a new High/Low pressure switch.

I had contacted the BG distributor in my area and they said that the frigiquiet oil also has a dye in it. Is it supposed to come that way??

Frigiquite is a blue colored oil.

Ok Larry I'll use R-12 If I can find it legally..
I always want to use the best I can and if R-12 is the best for the system I'll use it if it gets me colder more reliable temps hell yeah! I'll use it. I had many other ??'s in the thread about manifold gauges and "anything else I for got" and none of those were touched on. And BG oil is dyed a floresent so checking for leaks is detectable under certain light Ok found some R-12 now I need some gauges (any good brand? ) found some BG frigi quiet so looks like I'm golden there How many cans of R-12 do I need??

The R-12 systems use a 1/4 inch flare fitting on both the high and low side service ports. Manifold sets (gauges with hoses) are easily available at any refrigeration supply house or online. Buy a basic set. No need to spend a lot of money for occasional use. A wise decision was made with the R-12. I would probably stay with the 500W mineral. Just my opinion. I know that mineral oil flows very good in an R-12 system.

My car is a 86 300 SDL (603.961)
so mineral oil instead of frgi-quiet ok I just want to use the best I can I am single and have no kids so my car gets all my attention and all the good "gifts" My compressor works (doesn't blow cold but engauges) only when I jump 5-7 pin with a wire on the Kilma so I'll order a new one I have voltage at switches by dryer center vents blow when 5-7 is jumped (test purposes) I found three cans of R-12 on craigslist near me for $60 seems like a good score I will weigh them on my scale before I pay for them though Seems like I have almost everything lined up but the gauges should I replace the schrader valve cores for "good measure" |

where did you get a compressor for 100 bucks just in case I need one
or was it one of those sweet deals my compressor only engauges when I jump the 5-7 pin on kilma So I will order one unless someone can talk me out of it ? but atleast it engauges oh and sticker said 2.8lbs. I think so three cans of R-12 useing a side tap on a warm day should be good |

only get the kilma if you have tested it to be bad. BC has the info on that...
you will not get compressor engagement if you don't have proper refrigerant levels. |

It's a Ready Aire unit and it's been a good compressor so far. Quote:
