A vehicle cooling system comprises an oil circulation circuit in which a cooling oil is circulated by an electric oil pump to cool a predetermined cooling target with the cooling oil; an oil temperature sensor detecting an oil temperature that is a temperature of the cooling oil; and a control device including a cooling control portion outputting a rotation command for operating the electric oil pump so as to cool the cooling target. The control device includes a pump abnormality determination portion outputting the rotation command to the electric oil pump to determine a presence/absence of abnormality based on a rotation state of the electric oil pump when an operation stop time of the vehicle is longer than a predefined determination permission time and an oil temperature detection value detected by the oil temperature sensor is higher than a predefined determination permission temperature.

A vehicle liquid testing system includes a liquid testing apparatus with a form factor of a dipstick. The system includes a sensor that detects a property of a fluid in a vehicle and emits a signal indicative of the property. A transmitter receives the signal from the sensor and transmits the signal. A controller receives the signal from the transmitter and compares the signal from the sensor to a threshold level to determine a condition of the fluid.

A fan housing includes a housing body for accommodating fan components and an outer casing which surrounds the housing body in circumferential direction. The housing body has at least two webs extending in a circumferential direction on the radial outer side. The outer casing has at least two ribs extending in the circumferential direction on the radial inner side. The ribs, in the assembled state, between the housing body and the outer casing, form a channel circulating in the circumferential direction for receiving and holding a heating band. The outer casing has at least one guiding rib directed in the radial direction toward a housing body as well as into the channel and extending in the circumferential direction.

Methods and systems are provided for controlling coolant flow through parallel branches of a coolant circuit including an AC condenser and a charge air cooler. Flow is apportioned through each of an air-conditioning condenser, a charge air cooler (CAC), and a transmission oil cooler (TOC) of the coolant circuit to maintain an estimated transmission oil temperature (TOT) below a threshold. The TOT is estimated from a torque converter slip ratio.

A method of manufacturing a thermo valve includes an overlaying step of overlaying a valve body onto a thermo actuator so as to cover a groove portion; and a caulking step of caulking an installing portion of the valve body onto the thermo actuator. The caulking step is performed by pressing, by use of a jig, the valve body and the thermo actuator toward an axis center in a radial direction. A pressing face of the jig has a short side portion and a long side portion longer than the short side portion. Pressing is performed with the long side portion being substantially in parallel to the axis center of the thermo actuator and the short side portion being substantially in parallel to the groove portion.
