  • Q:

    Is this a fail-safe version which, in the event of mechanical failure, will stay open rather than shut causing an under heat condition versus an OVER HEAT condition?

      Hi Daniel! No, this is not a "fail-safe" version thermostat. Please provide us with your vehicle's year, make, model and engine size so that I can help you further.
