Vehicle coolant reservoir

A coolant fluid tank for a vehicle, comprising:

• a rear wall that operably forms at least a portion of a firewall at a rear of an engine compartment for a vehicle;
• a one-piece tank component engaged with the rear wall to form a coolant reservoir in the engine compartment, the tank component comprising a radiator port to receive fluid from the radiator, and a water pump port disposed at a bottom of the tank component to provide fluid to a water pump;
• and
• a gasket disposed between the rear wall and the tank component to operably mitigate fluid leakage.

A system for a vehicle engine coolant tank, the system comprising:

• a rear wall comprising at least a portion of a firewall panel disposed at a rear end of an engine compartment of a vehicle;
• a one-piece coolant reservoir component operably engaged with the rear wall to form a coolant reservoir, the coolant reservoir component comprising a fill port to operably add coolant to the coolant reservoir, the coolant reservoir component further comprising one or more structural attachment points formed into the one-piece coolant reservoir component, wherein the attachment points provide structural support for operably mounting a vehicle frame-mounted component;
• a gasket disposed between the rear wall and the one-piece coolant reservoir component to mitigate fluid leakage;
• a fluid level indicator disposed on a rear side of the rear wall, the fill level indicator operably, visually indicating a level of coolant disposed in the coolant reservoir;
• and
• a fluid level sensor disposed in the coolant reservoir at a low coolant level to detect the level of coolant at the low level when the engine compartment is rotated up to thirty degrees from horizontal;
• wherein the shape of the coolant reservoir mitigates loss of coolant through a pressure cap on the fill port when the engine compartment is rotated up to thirty degrees from horizontal, while maintaining sufficient coolant pressure.
