Lbs of Freon in a Behr system

[bavariaboy]

I seem to have a leak in my Behr ac system. How many lbs of freon or whatever should my mechanic put in the system?

 

thanks,  steve

Your mechanic should have a gauge set up that will tell when he gets to the correct operating pressure. I should add you can't mix refrigerants if you have a r12 system hold on it's going for about $118 for a 12 oz container if you can find it.

Steve,

 

I believe they used to specify 2.2 lbs. of R12 Freon, with a new Behr system for an ‘02. But Son of Marty’s approach sounds more relevant for a system that’s being repaired, and partially filled.

THIS IS WRONG: AS YOU’LL SEE BELOW, THE CORRECT ANOUNT IS 22 OUNCES!

I've seen anywhere between 2-2.4lbs. For what it's worth, I just charged my clardy system with a modern parallel condenser. I used about 28oz of R12 and it blows right at 38deg with good pressures.

its like 1.5 - 2 small cans of freon depending on the size of the condenser.

Concur with two small cans. I buy them at autozone, $5 bucks each.

I have 3 12 oz cans of R12 if you need them. $130 plus shipping which is what I paid for them. They have to be shipped ground Btw

Thanks guys. And I will alert my mechanic to your three cans, labphoto, if he needs them.

Some of the underhood sticker sets include Behr A/C Freon stickers. I’ve seen at least one version of these stickers on real live period cars. I’ve suspected that another version was borrowed from an e9 or e12.

 

Following, from a rusty 1972 tii, the first photo appears to show a very authentic Behr A/C sticker, for an ‘02.

 
22 ounces!

 

The second photo came with a set of under hood stickers. This is the one I suspect of having been printed for an e9 or e12.

2.86 pounds, or… 46 ounces?

 

Best regards,

I've used RedTek r12a in mine for years and it works great, I also use it in my 86 Carrera and it is even cold in there.

The Behr air conditioning installation manual is available in pdf form on the 2002tii.org website. If I recall correctly, it has the freon charge amount in the instructions. And remember, if yyou are going to use R134 instead of R12 you only fill the system with 80% r134 than the listed r12 amount.

You’re absolutely correct, Tom! But… I‘ve been unable to download it from the tii register website for the last month — hope it’s not gone forever — and I can’t find either of my printed copies!

Thank you, Tom,

 

That link worked for me!

 

So 22 ounces it is. That 46-ounce sticker is looking more out of place than ever!

 

Best regards,
