Thermal management module with loose slider valve for cooling circulation systems of the internal combustion engines essentially comprises at least an input which transfers the coolant from engine block and characterized by, - At least a body which provides housing for the elements of the thermal management module with loose slider valve and has two parts impending upper and lower and transmits the coolant from input - At least a space which is inside the body and in which components of the module is installed - At least a sliding loose valve inside of the space, which moves bidirectionally up and down along the axis of the space and controls the flow of the coolant liquid - At least an actuator with thermal element inside of the space which moves up and down on the axis of the space according to temperature change and through this change a force to be generated for driving a radiator valve and sliding loose valve and controls the temperature of coolant fluid. - At least a spring inside of the space which applies force on the actuator with thermal element in the opposite direction of the force generated by the actuator with thermal element - At least a radiator valve which controls the flow of the coolant fluid through the radiator output by opening and closing and which is connected to the actuator with thermal element - At least two primary connection elements which are in fact an extensity of radiator valve and transfer the movement of the actuator with thermal element to the loose valve by the holes which guide primary connection elements on the sliding loose valve - At least two guide teeth which are in fact an extensity of the body in and along the space which keeps the sliding loose valve on the axis of the space by guiding from both edges. - At least a body which provides housing for the elements of the thermal management module with loose slider valve and has two parts impending upper and lower and transmits the coolant from input - At least a space which is inside the body and in which components of the module is installed - At least a sliding loose valve inside of the space, which moves bidirectionally up and down along the axis of the space and controls the flow of the coolant liquid - At least an actuator with thermal element inside of the space which moves up and down on the axis of the space according to temperature change and through this change a force to be generated for driving a radiator valve and sliding loose valve and controls the temperature of coolant fluid. - At least a spring inside of the space which applies force on the actuator with thermal element in the opposite direction of the force generated by the actuator with thermal element - At least a radiator valve which controls the flow of the coolant fluid through the radiator output by opening and closing and which is connected to the actuator with thermal element - At least two primary connection elements which are in fact an extensity of radiator valve and transfer the movement of the actuator with thermal element to the loose valve by the holes which guide primary connection elements on the sliding loose valve - At least two guide teeth which are in fact an extensity of the body in and along the space which keeps the sliding loose valve on the axis of the space by guiding from both edges.
