Okay so i'm hoping recharging that AC system isn't expensive. All bolts are out but having trouble getting the heater hoses off the heater core so I can pull the box out. Any tips, I can't even get a scew driver in their to break the seal on the inside. Hose clamps are off?

 

Twist and pull lol.

 

I don't know what was holding them on there cause I had all my strength twisting and pulling and they never came off. I just crimped them with vise grips on the heater core and they came right off.

Anybody know the proper procedure for filling the AC system once I get it all back together. I know you can buy the recharge kits but am I best to just take it to a shop to get it filled?
