  • Radiator and lateral bump stop therefor
    Patent number: 11098965
    Abstract: A radiator includes a radiator frame, an array of tube assemblies each including a coolant tube and a tube clip supported in the radiator frame, and a lateral bump stop fitted between the array of tube assemblies and the radiator frame. The lateral bump stop includes cushions arranged in a staggered cushion pattern complementary to a staggered packing pattern of the tube assemblies with each of the cushions in contact with the tube clip of one of the tube assemblies.
    Type: Grant

  • Method and system for detecting thermostat failure in an engine cooling system
    Patent number: 10119455
    Abstract: A method for thermostat failure detection in an engine cooling system is provided. The engine cooling system includes a coolant pump and a thermostat for providing a coolant flow between an engine and a radiator. The method includes determining one or more engine parameters. Further, a pressure difference between a coolant pump inlet pressure and a coolant pump outlet pressure is determined corresponding to the one or more engine parameters. The thermostat failure is detected when the determined pressure difference is outside a predefined range of pressure change defined corresponding to the determined one or more engine parameters.
