Does anyone know the effect of overfilled AC coolant i brought the meter to measure the coolant and it reads in the yellow which is warning for almost or overfilled, does anyone know if this would cause the ac to blow warmer at slower speeds but fine at high speeds?

AC donest have coolant it has freon., youll kill your AC if you run it overfilled for too long, you need room to compress the freon.

well on the meter it measures in the yellow which is warning from over filling but it is in the warning area is there any way reverse it

you risk exploding your Max in 3rd gear.

J/K - not sure how but emptying some freon would solve the issue.

Thats funny, isnt it illegal to vent it into the atmosphere? do places that do AC work have a special tool that maybe they can purge my lines so i dont finish destroying the ozone?

our cars do not use freon they use 143A refrigerant. you can bring it to any shop that does A/C work and they can fix it right up for ya

you mean 134a

is the 134a the or 143a which ever it is, is this the stuff you can buy and add in at your local parts store?

Yes.

freon is illegal to vent, i neglected to edit my post saying its R134A, the R12 they used to use is illegal to vent beacuse it contained CFC's. the new R134A does not.

ok so your sayin it wont hurt the ozone if i do decide to vent it?

epa still considers venting r134a illegal since it is a greenhouse gas. although a can of air duster for computers is basiclly r134a.

Freon = R12
R12 is not always called freon.
Freon = dupont brand for r12

oh and to answer your question about overfilling. your evap will be over filled. and it will not allow the r134a to boil. there will be no airflow over the r134a vapors in the evap. If you dont understand what i'm saying, consider this. Take a large Fan, and get a Big block of ice the size of a freezer. if you turned on the fan, and pointed it towards the block of ice, you would be able to feel the air at all.

I messed up my condenser this way.

well i wont fill as bad about venting it now that i know it wont destroy the ozone any more than it is

be prepared to be fined by the EPA.

In the United States, ANYONE working with refrigerants must be certified by the EPA. Most STATES also now require licensing to work with any refrigerant. If using old compressors, the refrigerant in the system MUST be recovered by an EPA certified technician - this includes r134a systems. Fines for venting refrigerant can range into the $1,000's.

good bit of info, i'm not doubting its credibility, but why not ban it like they do with R12 refridgerant

who would know

The people reading this thread.

lol

frozen passengers?

This post is hilarious, it's not like your dumping your oil change oil into a salmon hatchery or something. Just vent a little bit out until it is in the green. I don't think that 1/2 lb or less of 134a is going to do much. Contrary to popular belief man can't totally destroy the earth. The government has more things to worry about like illegals AND terrorists coming across the border.

So does that mean that it's OK to keep going without caring about the environment, just because "man can't totally destroy the Earth"?

doesnt have freon either it has environmentally safe R134a......and if u get a recharge and u overfill it it will spit out hot air not cold air.....if u overflow radiator coolant it will go into the overflow if that fills up beyond capacity it will spill all over ur engine bay where the resivoir is....as afar as venting ur 134a if u remove ur compressor....u wont be fined unless u get caught....so if anyone asks if they see.....its just steam from the radiator.....

r12 is what was killiing eagles along with the ozone, and they banned it because all the refridgerators and air-conditioners in dumps were leaking. one guy venting just a little bit will do nothing compared to 10's of 1,000's of air conditioners with refrigerant that actually harms stuff. like the ozone. and i really doubt that he would get fined for it. the epa is not so retarded that they follow around people to make sure they dont vent their air conditioners.
if you vent it though i would were a respirator. just in case. and i would do it on a windy day

This doesn't apply to people working on their own cars.

why do you say that?

cus no one of authority would be watching. if you do 100's of cars a year, thats a lot of refridgerant and epa wants to make sure your getting rid of it the right way. if you do it in your driveway, no one will know

The law was written for AC service businesses specifically.
