hi folks,

it is hot yesterday in New York. I feel my A/C is not really cold. I think the freon probably is low. So I am trying to check it out and charge it. But the problem is I can not locate the freon check window. I found the black bottle with a cap mark "H" just behind the driver side grille. I check the service manual it shoe the same location. But I still can not find it. Stupid me <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" />

I can not find the low service port either. can somebody tell me where it is. really apprecaited.

the low service port is on the a/c pump

the window is on the top of that black bottle you found with the high service port. it should be a little sight glass a little smaller in size than a dime. if you have truck running with a/c on, you should see stuff moving through the glass as the system cycles.

If you get a small container of R-134a and the hose to hook it up to the car, you should be able to recharge the system pretty easily, but you need to be careful. Because your low-side fitting is on the compressor, the chances are greater that you can damage/ruin the compressor by allowing liquid to enter. When you charge your A/C system, don't turn the can upside down - leave it right side up. It will take longer, but you won't hurt the compressor. If you want to make it charge a bit faster you can place the R-134a can into some warm water to increase its pressure.

thanks for your help. however it is not there. <img src="/forums/images/graemlins/confused.gif" alt="" /> <img src="/forums/images/graemlins/confused.gif" alt="" />

Mine is 99 Montero (not support), is it different than yours ?

If you are looking for the sight glass (the window you mentioned), there may not be one. Not all A/C systems have them. If there were one it would likely be on top of your receiver-drier, but looking at your picture there isn't one there - only the high-side service port. Your low-side lines will be larger in diameter than your high-side lines. What you need to do to find the low-side service port is follow the larger line coming off the compressor. If you follow it all the way back to the firewall, you're bound to find the low-side fitting. Though the low-side line is larger than the high-side line, the low-side fitting will be smaller, and it may have a platic cap with an "L" on it. Like Scottie said, the fitting may be on the compressor itsself. It could be anywhere between the compressor and the firewall.

thank you for your detail explanation. I will try to figure it out what tis the problem of my A/C systems.
