An engine block heater is for an engine block having passage walls which define a fluid passage. The engine block has a heater socket which extends from the outer surface of the engine block toward its interior. The heater socket is separated from the fluid passage by the passage walls. The cartridge heater comprises a heater housing having an exterior heating surface. The exterior surface has substantially the same shape as the heater socket enabling insertion of the heater housing into the heater socket and substantial heat transfer contact between a substantial portion of the exterior heating surface and the heater socket. A connector mounting is attached to the heater housing. The connector mounting is adapted for connection to an electrical power source. The heater housing has a heating element therein which can be heated by electrical connection of the electrical power source to the connector mounting enabling the heater housing to transfer heat to the engine block. A quick-release fastener is attached to the heater housing for releasable connection of the heater housing to the outer surface of the engine block.
Chauffe-bloc pour bloc-cylindres comportant un chemisage permettant le passage d'un fluide. Un manchon pour le raccordement de l'élément chauffant affleure à la surface du bloc-cylindres et se prolonge vers l'intérieur. Le manchon de raccordement est séparé des passages par les parois de chemisage. La cartouche de chauffage est logée dans un boîtier dont la surface extérieure est chauffante. Le boîtier de l'élément chauffant, dont la forme est sensiblement la même que celle du manchon de raccordement, s'insère dans le manchon de raccordement pour assurer un transfert thermique optimal. Un connecteur fixé au boîtier de l'élément chauffant est destiné au raccordement à une source d'alimentation électrique. L'élément chauffant logé dans le boîtier, dont la chaleur est transférée au bloc-cylindres, est chauffé par raccordement à la source d'alimentation électrique par l'intermédiaire du connecteur. Un raccord rapide fixé au boîtier de l'élément chauffant permet le branchement/débranchement rapide du boîtier à la surface extérieure du bloc-cylindres.
