    I popped my housing apart and installed a Sierra 160* thermostat. I salvaged the inlet nipple from another housing and used it on mine. Cant beat a $40 dollar 160 degree thermo!!

    Exactlly the same as OE BRP thermo but in a 160*.

    i am looking for a 131 or 140 degree Tstat that will fit in like the 158 that was found earlier.

    Did you ever find one? I have the 158* DIY thermostat mod done but was thinking to go to the 131 or 140 as well.
