    can't find my manual...
    13 psi or 16 psi?
    thanks.

    According to various parts sites, 16 psi.
    E.g.
    http://www.autopartswarehouse.com

    and

    All Civic-based vehicles use OEM ND 0.9 bar rad caps. This equates to
    13psi. Do not use aftermarket 13psi rad caps.

    Do not use aftermarket 1.1 bar (16psi) rad caps on your Civic. In fact, do
    not use aftermarket rad caps at all.

    The site http://catalog.drivewire.com has photos and shows
    an ND rad cap for both the 91 and 92, the 91 Civic's rated
    at 13 psi, the 92 Civic's at 16 psi.

    Autozone's parts site specifies a 16 psi rad cap for the
    1992 Civic, and a 13 psi rad cap for the 1991 Civic. The two
    parts sites I gave earlier do the same.

    The free online UK Factory Service Manual for the 95-97
    Civic says the opening pressure is 14-18 psi.

    My mistake. I had read the specs wrongly. The cap rating required is in
    about the middle of the operating pressures specified the shop manuals, not
    at the bottom of the range as I had previously thought.

    The '92-'95 Civic does in fact use a 1.1 bar cap, as does the '96-'00
    Civic. Looks like Honda went across the board with 1.1 around 1992.

    Still, aftermarket caps are a bad idea.

    so.... does anybody want to buy a neato Mr. Gasket aftermarket 13 psi
    cap with a thermometer built in, that it turns out doesn't fit Hondas
    anyway? (diameter is OK, but looks like it wants a taller radiator
    neck)
