An engine cooling system is provided, which includes a water jacket through which coolant flows, a heat exchanger that cools the coolant, a first bypass passage that bypasses the heat exchanger and recirculates the coolant to the water jacket, a radiator passage that recirculates the coolant to the water jacket via the heat exchanger, and a flow control device that is installed at a location where a coolant passage branches into the first bypass passage and the radiator passage and performs a water flow control to adjust a coolant amount flowing into the water jacket by adjusting a coolant amount flowing through the first bypass passage. A thermally-actuated valve connected with the radiator passage via a second bypass passage is provided to the first bypass passage, and when this valve opens, the coolant flowing through the first bypass passage flows into the radiator passage through the second bypass passage.

An electric coolant pump of a cooling circuit of a motor vehicle includes a pump chamber, a suction line leading into a suction side of the pump chamber, a discharge channel leading out of a pressure side of the pump chamber, and an electric motor with a controller. The electric coolant pump includes a heater including an electric heating element which projects into the suction line or the discharge channel and which can be flushed by the coolant. The electric heating element includes at least a first heating element operating state in which the electric heating element can be operated from a power supply system and a second heating element operating state in which the electric heating element can be operated from an on-board power supply system of the motor vehicle. The controller of the electric motor is configured or programmed such that the electric motor also includes at least two operating states.

This disclosure relates to improved water pump assemblies and related methods. The water pump assemblies can include pre-mounted fasteners and gaskets to facilitate easy installation or reinstallation of the water pump assemblies. The water pump assemblies further can include a temperature-control valve assembly positioned within a housing of the water pump assembly. The water pump assembly can include a variety of other pre-installed components. Other embodiments are disclosed.

A module for a fluid circuit of a vehicle includes a unitary housing. The unitary housing of the module contains a fluid moving device, a fluid control device, and a power sharing connection. The power sharing device is configured to provide power to the fluid moving device and the fluid control device.

An engine is disclosed having a water cooling system allowing efficient cooling of the exhaust valves to prevent temperature gradients from building in the engine. Water is therefore pumped through the engine though first and second water cooling cores which discharge through the head. A water manifold is positioned over the discharge opening and includes couplings for the radiator supply, radiator return, water pump supply, oil cooler supply and oil cooler return. The engine has separate chambers to isolate the pistons and cylinders, and reed valves cover the chambers and allow the blow-by gases and oil to enter the oil pan during the power stroke of the engine cycle.
