Everything I read says 134a refridgerant, but the nipple is to large for the adapters from advanced auto/pepboys 134a kits. It's a 1995, not OBD II, and it has me thinking it uses R-12 refridgerant. Anyone know for sure? It's not marked anywhere I can find. | | | 07-10-2014, 01:17 AM | #2 | Senior Member Join Date: Jul 2013 Location: Lakeland, FL Posts: 229 | It should be 134a. That is what is in my 95 318ti. | | | 07-10-2014, 01:18 AM | #3 | Junior Member Join Date: Nov 2012 Location: Collegeville, PA Posts: 16 | What's the build date of yours? It should be on the vin plate in the drivers door jam. I think it was a split year. there's no way to test that i know of. I did compare the nipple to another car I have and it's definitely not the same size. | | | 07-10-2014, 05:40 AM | #4 | Senior Member Join Date: Oct 2008 Location: Los Angeles, CA Posts: 1,464 | All ti's should be 134a. Make sure you're trying to connect to the correct port (suction). __________________ 1995 318ti Base - Cosmosschwarz/Sandgrau R.I.P. 1997 318ti Active - Alpinweiß III/Sandgrau 2013 328i Coupe - Le Mans Blau | | | 07-10-2014, 11:42 AM | #5 | Junior Member Join Date: Nov 2012 Location: Collegeville, PA Posts: 16 | It's the hard line with the black cap, there's really only one place you could connect it. If anyone could get a picture of the valve under their hood it'd be appreciated. | | | 07-11-2014, 01:48 PM | #6 | Senior Member Join Date: Aug 2009 Location: Georgia Posts: 595 | The suction charging port is by the firewall behind the shock tower on the passenger side. The one in the front by the radiator is the high side. Do not charge on the high side. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 | | | 07-11-2014, 05:20 PM | #7 | Junior Member Join Date: Nov 2012 Location: Collegeville, PA Posts: 16 | Aha, that's interesting. Everything else said it was right behind hte headlight, but back there is quite diffrerent. Thank you I will check that out as soon as i get home. | | | 07-14-2014, 04:06 AM | #8 | Senior Member Join Date: Mar 2005 Location: Portland Or Posts: 2,666 | LOL and thats why they are different sizes.. ! FYI I've topped mine off a couple times over the last 8 years and I found its almost impossible to get the right charge using the little refill bottles, I finally bought a real guage set and don't have to dink with it.. The operating spec for the pump on the 95 is freeking tight, 5lbs too high and the pump will stall and like 4 lbs too low and it don't work for sh** so I highly recommend a real dual guage high and low side charge setup.. My theory has always been its really an R12 pump with a R134 expansion valve ....

Just need someone to turn the hose on while i'm under hte car with a smoker to figure out where it's coming from. I can hear it easily. | | | 07-14-2014, 11:52 AM | #10 | Senior Member Join Date: Aug 2009 Location: Georgia Posts: 595 | Quote: Originally Posted by pdxmotorhead LOL and thats why they are different sizes.. !

I vacuum the system and weigh the charge. Too much and the engine feels like it is mis-firing when the system high side goes up the roof then high pressure switches fan to very high speed. Too little and it barely cools. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 | | | 07-14-2014, 11:53 AM | #11 | Senior Member Join Date: Aug 2009 Location: Georgia Posts: 595 | Quote: Originally Posted by nasomi I got it going, but I have a fierce leak somewhere, the o-ring must be all but gone.

If you don't have one, put a dye and UV light will reveal the leak. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 | | | 07-14-2014, 12:19 PM | #12 | Junior Member Join Date: Nov 2012 Location: Collegeville, PA Posts: 16 | I can hear it leak out as soon as I charge it, it takes about 5 seconds to completely empty from full, so it should be easy enough to spot. It is tough to get to but I have a proper gauge, I just can't get it to stay because it leaks out right away. | | | 07-14-2014, 08:02 PM | #13 | Senior Member Join Date: Aug 2009 Location: Georgia Posts: 595 | Using R134A refrigerant to find a big leak is quite expensive. You need to pressurize the system with nitrogen to find the leak. Fix the leak, vacuum then recharge the system. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 | | | 07-14-2014, 08:04 PM | #14 | Junior Member Join Date: Nov 2012 Location: Collegeville, PA Posts: 16 | It is quite expensive, but blowing out $15 worth of 134a is significantly cheaper than any alternative I'm aware of. Buying a system to pressure ize the tank, buying the tank to hold the nitrogen, buying hte nitrogen, is probably going to cost me more than $15. | | | 07-14-2014, 09:28 PM | #15 | Senior Member Join Date: Aug 2009 Location: Georgia Posts: 595 | Quote: Originally Posted by nasomi It is quite expensive, but blowing out $15 worth of 134a is significantly cheaper than any alternative I'm aware of.

If you don't have the hvac tools like nitrogen tank and gauges then R134a as a leak tester is cheaper. But that is not the trade practice for hvac techs and shops. Good luck finding that leak. __________________ 1996 Ti 280k miles and still going.... 1993 964 - holding on to this one 2001 Burban, 240k miles 2018 Suburban Z71 | | | | | Currently Active Users Viewing This Thread: 1 (0 members and 1 guests) | | Posting Rules | You may not post new threads You may not post replies You may not post attachments You may not edit your posts HTML code is Off | | | |
