Are the AC service ports on Discovery's (my is a '97) standard? I bought a service kit (Stop Leak and Refrigerant), pulled the cap on the low pressure service port but I can't get the service hose to engage. i.e. lock on. Wondering if LR designed port with unique connectors so as to force service through dealers.

 

no, its standard epa regualted size, make sure youre not on the high side port

 

Mine was tough to get on too. You just need to wiggle it and push hard.

 

I think I'm blind ,can anyone tell me where the low pressure port for charging the a/c on a 2008 LR 2 is located ?
