ac recharge.

Well, "420g ± 50g" means exactly that. If you're evacuating the system and using an accurate scale to recharge, you put in 420g. If you goof and wind up anywhere between 370 and 470 g, you don't necessarily have to do the job over (though at either one of those extremes it wouldn't be such a bad idea).

 

So for the Prius C is 470 grams of R-134a? i want an exact weight capacity.

 

The label photographed in this thread clearly shows 420 g, with an allowance for operator error of 50 g on either side of the correct charge.

But as lech suggested, it would be best to look under your own hood for your own label. The numbers there might be different (but how to read "correct charge ± error allowance" will not change).

 

I would stay closer to the 420 g if possible the Prius C has a very small refrigerant charge and 50 g is over a ounce and a half of refrigerant. The smaller the system charge the more sensitive it is to smaller increments of plus or minus.

Sent you do not have a sticker under your hood was it in the front in the accident before repaired at a body shop usually they leave the stickers off.
If this is the case you possibly have any aftermarket condenser of a lower

This is a very small refrigerant capacity system it is very sensitive to overcharge or under charge 50 g is a ounce and a half of refrigerant it does not seem like much but it does make a big difference try to stick closer to 420 g if possible with a very accurate scale it will work in either case.

Since you do not have it under hood sticker has your vehicle been in a front end collision repair it at a body shop they usually leave the stickers off after repair. In that case you may not have the original condenser you may have a lower quality aftermarket condenser that is not as good as the original it may have fewer cooling fins and few were refrigerant passage cooling tubes that reduces its heat dissipation load. This case it messes with the amount of refrigerant charge reducing your cooling capability on very hot days.

As for turning off your vehicle without turning off your air conditioning it all depends if you have a smell issue in some areas of the country people have mold in mildew spores in the air and different pollens that collect in the evaporator case and if they often shut their vehicles off with the water without drying it out first they get a smell .
I personally do not have that problem run my air conditioning 24 seven and I shut off my vehicle without turning off the air-conditioning everybody’s situation could be different.

 

I see, thank you very much for answering. Also with 90° F outside temperature my Prius A/C temperature is between 9° / 12° C when i came back home after 1 hour and 30 minutes, do those temperatures looks normal? This vehicle i think it still have the original refrigerant from facotry, i don't know if i should add a little more.

 

Well i looked under the hood and i can't see any label, and that one in the picture is from a 2012 Prius, not Prius C, i don't know if both vehicles have the same capacity for refrigerant.

 

9°C to 12°C is an excellent temperature for 90° F ambient temperature. If you’re just a little bit low on refrigerant your compressor will just have to work harder spin faster to try to move more refrigerant to compensate for the loss of refrigerant. It will take a longer time for you to get down in temperature because of the lack of refrigerant. And yes that is a picture off of my Prius C refrigerant label.

 

As lech said, that probably indicates there was body work done in front and the piece where the label's supposed to be got replaced.

For that case, I'd recommend either the repair manual, or going with whatever lech says.

 

And I would stay away from just topping off for adding refrigerant go for a complete drain and recharge This is the only accurate way

Your location indicates Puerto Rico different countries get different cars on the same platform sometimes the engines are different. Labels can be different

 

I do not know who gave you the information that the sticker is not for my Prius C but from a Prius but I think you should scratch that person off your list as a recommended source of information on Prius C.

 

Then where exactly i can find that label from the last picture? which place of the hood? my Prius have all those label except the last one.

I thought it was from a Prius and not from a Prius C because i could not find such label anywhere.

 

Maybe it’s possible that label in whatever country you purchased your vehicle doesn’t come with it but I thought it would. That’s why I said if it was ever in an accident possibly a body shop never replaced it you would just have to ask at the parts counter at Toyota to order another sticker they go by the Vin number

 

Well i can say very confidently that this vehicle was not in an accident that required major repairs like replacing the condenser, maybe the hood since i can't find the label, also in the hood there was a sticker that said ''Toyota R Dot'' Here some pictures. The only deformation that i could find in this vehicle was right behind the Toyota logo of the front bumper, it was bended a little bit, making the bumper not to look alienated with the hood, i fixed it with my hands. But that's all i can see, maybe it was a slight front crash, that's all the damage i could find.

 

I see, well then i will have to get new labels then. I'm starting to think that the hood in this vehicle was replaced, but i don't know, maybe it was when i took it to the tinsmith, i asked him to only fix the shape of the hood to make it look aligned with the bumper, but he said that i was not worth it since the hood was losing paint so it would be better to repaint it too.

 

Since you’re in Puerto Rico I think that’s what you’re area was a read on your profile maybe possibly in your country it’s not every legal requirement to have engine stickers and labels and hoods like here in America ??. The black sticker with the Toyota emblem with your Vin number definitely looks OEM from Toyota

 

The word tinsmith I have not heard in a long time. My great grandfather was a tinsmith in the Pennsylvania coal mines

 

Which section of the great commonwealth of PA?

My grandfather was a blaster in the coal mines of Northeastern PA.

Most of my family has been in that section of the state since the 1700's.

Not this guy though as I saw the best coast light.

 

Yes most of my family on both sides of my family have been here since there early 1700s. My father side of the family Hazleton Pennsylvania.

 

Our ancestors may have met then.

We are from the Dallas / Harvey's Lake area just west of Wilkes-Barre.

The mines around there were what my mothers father worked. And he had the black king to prove it.

Not sure if you have ever been back there, but it is a trip back in time compared to what we have here in the Bay Area.

 

Went back there one time when I was 17 or 18 years old with my father. One family member owns one of the big cold strip mines. Other family members Live on farms with lots of land. I was surprised every morning we would get up the first thing they would do is drink beer and skip breakfast. They had a specialize separate refrigerator that had a giant keg of beer in it with a beer tap sticking out the side. We immediately would go out in the morning in the big backhoes and large dump trucks to go work the land and the fish farm we’re building a new man-made lake on their farm get drunk every night throw up they would carry me home wake up in the morning and start all over that’s what I remember from Pennsylvania.


The women did not associate with them and they stayed in the kitchen cooking dinner for the men were served and ate out on the table I was curious and ask the question why aren’t the women eating with us my old uncle said woman’s place is in the kitchen. Got that barefoot and pregnant mentality. It was a world and a land long forgotten and lost back in time.

Me being raised and born in San Francisco it was culture shock.
