    • A cooling system has a radiator for cooling coolant of an automotive engine, cooling fan (33) for cooling the coolant in the radiator (22), and a thermostat (1) for controlling coolant temperature. The thermostat (1) has a housing having a flange (16), an actuating rod (3) secured to the housing at a first end thereof, a guide member (4) slidably mounted on the actuating rod (3), a resilient seal spool (5) provided around a second end portion of the actuating rod (3) and secured to the guide member (4), a heat sensitive cylinder (8) housing the seal spool (5) and secured to the guide member (4), wax pellets (7) provided in the heat sensitive cylinder to enclose the seal spool (5). The flange (16) has a hole (19a) so as to pass a coolant, and the thickness of the resilient seal spool (5) being set between 25% and 5% of the diameter of the actuating rod (3), thereby reducing a spring constant of a return spring of the thermostat (1). A cooling fan switch (67) is provided for starting the cooling fan (33) at a low coolant temperature.

    • A guide member is slidably mounted on a rod, a resilient seal bag is provided around a first end portion of the rod and secured to the guide member, and a tubular sealing member is slidably mounted on a second end portion of the rod. The rod is inserted in a heat conductive cylinder secured to the guide member, and wax is filled in the heat conductive cylinder. The seal bag has a base portion and a bag portion, and is engaged with the rod only at the base portion to form a gap between the bag portion and the rod. The gap is charged with lubricating oil. The sealing member has a tubular body, a skirt portion, a closed head portion, and a plurality of annular grooves formed in an inner wall of the body. The base portion is secured to the guide member, and the head portion is engaged with an end of the second end portion of the rod. A seal device is provided between the guide member and the rod so as to prevent the lubricating oil in the seal bag from entering in the sealing member.
