Std & Hi press pressure safety rad caps now avail
we now have a better alternative than the ridiculously expensive TRD radiator cap. we now have stocks of STANT (USA) caps for $27.50 incl GST but plus post. These also have a safety relese lever that allows you to vent any steam to the overflow bottle. They come in standard 13 lb (90kpa) or 16 pound (110kpa) varities. We use the latter on our race MR2 to stop it continually boiling when we stop. The venting action also makes it easier to bleed/fill the system as you can safety vent then open the cap as soon as the thermostat opens, and gradually add water.
