You could try a new thermostat and a new raidiator cap. Like NISMO or Greddy, that lets off pressure at at lower heat levels or something like that. It's early on a sunday morning and I can't word things right......also, you can try Redline Water Wetter which should cool things down a bit. Good luck!
