how much freon for a 98 Maxima? Pages: 12

aliaZ on Mon June 23, 2008 8:55 AM User is offline

Year: 1998
Make: Nissan
Model: Maxima
Refrigerant Type: R-134a

Thanks

1998 vehicles don't use freon, they use R134a. Freon is DuPont trade name for R-12.

NAPA book (linked on this site) says 25 oz R-134a. Look for a sticker on the car though; if you find one go by it as it's a more definite answer.

Second source says 25 ounces of R-134a (Suva- if you want to talk brand names here)

The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......

Johnson and Johnson also owns the trade mark "Band-Aid" that a lot of folks do not know also, but how many times do we ask for a Band-Aid when we cut ourselves?
The folks that come here or not experts in this industry or they would not have to come here to ask the experts, and I would say 99% of them call 134 A "freon", so for us to get technical with them over the patent name of freon is really irrelevant,we should be kinder and more gentler. JMO.

But this is also an educational opportunity- to learn- so a reminder of a/c correctness is always welcome.....

I have actually been invoiced for a 30 lb tank of "134a Freon"---I gently asked the sales rep what was I buying- I then asked him where does it say "freon" on the tank.....he threw me out....evidently he doesn't like to be corrected....

And I totally agree with you, but when you don't attempt to even help someone with there immediate issue and start giving them a Chemistry lesson I personally just thought this was a tad out of line, but as I said "Just My Opinion" and we all have them and I respect the opinions of others as well, no big deal.

Maybe we should just call it all "refrigerant". GRINS

JJM on Thu June 26, 2008 4:11 AM User is offline

But if you actually did put "Freon" in an R-134a system it would be a problem. How do we know if the person isn't contemplating recharging with some old cans of R-12 found lying around the garage?

I prefer the term "refrigerant" too.

In this case the proper term is Refrigerant, not Freon. Cussboy may have came off a little harsh with his correction, without answering the original poster's question, but he was setting him straight. I think it would be unprofessional to not state the difference and to lead the poster on thinking that calling R134a Freon was correct. However, I let it slide all the time.

I see R134a advertised as freon in Harborfreight & Kragen flyers all the time. I understand why the general public may not know the difference. Even the guy at the autoparts counter sometimes doesn't know the difference.

There is a reason they label it R-134a, R-12 versus HFC-134a and CFC-12, and it has nothing to do with chemistry.

Those old cans will be labeled "Refrigerant 12" unless they were DuPont brand.

We have a Canon photocopier in the office so of course it doesn't say "Xerox" anywhere on the machine, but that is what everyone calls it.

joe_mn on Sat June 28, 2008 8:30 PM User is offline

we just say copier at my office. we "copy" papers. the young guys don't know what xerox is. we send/get 90% faxes. our copier can also scan documents onto our network drive and i usually send email attachments. but a lot of our customers do not have computers or even use the internet. i design stuff on computers and use them alot but our customers are kind of technology shy.

As a novice to the whole A/C repair journey myself, I can assure you that the original poster will never forget the difference. I know I won't ever call R-134 "freon"..... did I spell that right? While our ignorance sometimes stings, I know I for one am very thankfull for the help.

So you can't buy virgin R12 any more. Hmmm I guess the virgin R12 we have been buying for years is a fake! Give me a break, the video is cute but not factual with the R12 statements.

Is DuPont still taking R-12 orders or have you been buying over priced old stock on elsewhere?

Chick on Mon June 30, 2008 7:56 AM User is offlineView users profile

I just bought a couple small cans from Pep Boys for a top off about a month ago , it was R12 I assure you... Yes, they are selling reclaimed R12, and it has to be something like 98% pure, but the real stuff is still out there.. Even in 30lb jugs. Of course since it's no longer made in the USA the price is up there, but not as high as it was when the retro craze began, (forced upon us) It's actually coming down now.... Back then it made sense, somewhat, to retrofit, but today it makes more sense to keep R12 cars R12.. Just my opinion though...

PS: I still have a 30lb at the shop, but was at a friends house and it was easier to go the pep boys for his car...

The last time I had anything with a r-12 system was a 89 crown vic. Couldn't find any r-12 at the time so I tried Duracool and that worked great.

Did it work as well as it did for these guys?

That's funny, They must of got sued or something, When I looked into it a few years ago it was stated the stuff was not flammable. Lets say that i got lucky and the system did not leak 5 years later the car went to the wreckers with the a/c still working fine.

Duracool is simply a mixture of propane and butane. The exact same stuff that fuels BBQ grills and lighters.
