GTM stage 2 Air Conditioner Problem?

hindi1973

the confusing part we got 2 upgraded nismos caps , in the nismo below 2012 the radiator cap was the one that has pressure cap number on and the reservoir cap had no pressure ratings so when ppl changed the caps they changed the one going to the radiator hose and left the plastic cap for the reservoir as is or some upgraded their resevoir tanks to stainless steal so they close it with metal cap , on the 2012 nismos , the resevoir cap has the pressure rating on it and the one going to the hose has no ratings is just pure metal with no pressure rubber inside it , so it got us confused to which one to choose , so we changed both to the upgraded nismo one , but i have a feeling i should leave the one going to the hose as is with the one that has no pressure rating on it and no pressure rubber inside it .

u guys can google 370z nismo 2012 engine pictures , u will see how the 2012 nismo caps are put togather and then look at your engines or google older versions , hope u guys can chime in

thanks
