A/C filling

Post by P.Gaudreault » Fri Jul 03, 2015 4:55 pm

I would to fill my A/C because it is not very cold and when my engin run on park it is very not cold. If I buy a kit in Canadian Tire, does that kit fit for filling my Van?? Is it standard??
And finally, where is the damm plug on the Van for filling?? I can't find it.

Thank you.

Canadian Tire Kit with the 12a refrigerant. You may need more than one can.

You will find the low pressure connection just above the AC pump....just below your battery. You have to set the intercooler aside to get at it.

If you dual batteries its a very tight fit for your hand as the upper rad hose partially blocks access.

Here's a pic of the location of the low pressure nipple.
This is on my L400 with a single battery.

Thank you, with your picture I fund my plugue easly. But it is already full. I plugued my 12a refill and the pressure is already at 70psi. More than full. But I didn't let the engin running with the A/C fully open. I guest it is enought 70psi.

I'm not an A/C guy, but I did fill my ac unit. It should be filled to around 13 to 14 pis I believe. Thats no where near 30 to 38 psi.Make sure you fill it to low pressure side. The A/C worked great after I did the fill, but I must have a leak as it stopped producing cold after a few days. I think it's the schrader valve, Also It should be R134 not R12. any AC unit made after 1996 uses R134 from what I found in my research.
Hope this helps.

I used the 12a refrigerent kit from Canadian tire and the plugue fit great. I used the green plugue that izack98 shown to me. On the package they say to fill till 30 to 38 PSI, I don't know if each car is different. How your A/C work, went you are on park and let the A/C working. Is the air become warmer?? Colder then the outside temp but the air become colder while I drive.
