hey im trying to refill the freon in my car, but im having a difficult time finding the AC low port. I found the AC high port near the radiator, but can anyone tell me where the low port is at?

 

its r-134a...freon isnt allowable by law anymore i dont think. I seem to remember the low port being tucked away down low in teh engine compartment but i could be wrong. Do you have the correct guages?

You want your low side pressure to be around 32-35 as a rule of thumb.

 

ok, i was able to find the LOw port. its located on the driverside near the top of the engine.

i believe i do have the correct guages, however when i turned on the car and started to recharge, my guage was reading around 120, no where near 32-35. Can anyone else confirm if the pressure is suppose to be aound 32-35

 

120 seems to be the high side reading

 

the low port will be MUCH colder than anything else in the engine bay. 120 psi is not going to cool anything down. Going from 120 to 35 will though.

 

Is your car out of warranty? cause the only reason you would be low on refrigerant is if there's a leak.

 

nvm, thanks guys, the reason my guage was giving me bad readings was because it only read one way. I was able to refill completely drain my car and refill with the correct pressure readings.

yes my car is out of warranty, and i do not have a leak. i just wanted to refill because for some reason i thought my ac wasnt blasting cold enough, so i had assume i had a leak. in the end, after all my work, my ac blasts exactly the same haha, i fail

 

oh well....at least you learned about the a/c system in your car for when it really does spring a leak.
