Looking at recharging my A/C system. Wondering if anyone knew what PSI the system should run at off the low pressure side? Thanks!

 

Pressures can vary greatly. Your best bet is to pull a vacuum on the system and either weigh in the charge or if you are using cans make sure you know how much refrigerant is going in. Your car will have a sticker on it telling you exactly how much the factory charge is in LBS and OZs
