Abstract
Provided is a thermostat monitor () comprising a thermostat open failure detecting part () for detecting an open failure of a thermostat when a condition is such that a radiator heat radiation amount () radiated from a radiator on a radiator-side cooling water channel is larger than a heater core heat radiation amount () radiated from a heater core on a heater core-side cooling water channel, and that a difference between the radiator heat radiation amount and the heater core heat radiation amount is equal to or more than a predetermined value A. Based on a temperature of engine cooling water detected by a temperature sensor positioned in the vicinity of an outlet of an in-engine cooling water channel, it is possible to detect the open failure of the thermostat relatively easily with certainty.
