I thought this might be a good place to post the attachment from the Stant Mfg. website since many members say they cannot find a radiator cap for the T. Mine just did the spewing fluid issue at 31,000 miles so I bought a new one from the dealer and it cost $21. Most I ever paid for a rad cap. The dealer is one hour from home and because I had my wifes car he would not warranty the cap so I bought it and my $50 Visa rebate from Nissan had already expired. Anyway Stant shows the radiator cap to be 42psi?? The recovery tank cap is supposedly 16 psi so that one should open long before the radiator cap does (unless the rad cap is bad). Anyway the part numbers are enclosed so i suppose you could order them as well as fuel caps, oil filler caps, etc.

Radiator cap is around $15 from courtesyparts.com probably plus shipping, so $21 sounds ok. The 2004 service manual has a section on pressure testing and specs the recovery tank cap = 14-18 psi. I could not find any spec on the radiator cap, so I think you are correct, the recovery tank cap provides the primary pressure relief.
