What is the correct pressure the radiator cap is supposed to be for a 2006 Highlander with a 3.3L?
I can't seem to find the correct pressure anywhere.

The Stant radiator cap catalog say 13 psi.for 2006. But for 2004, 2005 & 2007 16 psi. Weird.

16 psi, 1.1 bar!

The radiator cap itself might have the spec stamped or printed on a label. It's more commonly expressed in kilopascals (kPa) or bars on anything that isn't domestic. Bars are the easiest to convert to PSI. Just take any spec shown in bars, multiply it by 14.7, and that will be your cap pressure spec in PSI.
