Most modern vehicles have a reservoir from which extra coolant can flow to the radiator and vice versa. Coolant in this reservoir usually indicates the radiator has sufficient fluid. Checking the radiator by opening the cap is a secondary means but the level may vary by temperature.
It is to let you know when an underground oil tank is filled to its capacity so not to overflow.
I checked my owner's manual - it listed radiator capacity at 6L.
The radiator capacity for a 1998 Toyota Camry is two gallons. This includes coolant stored in the engine block and radiator.
I'm not sure of just the radiator capacity, but the total coolant capacity is 11.8 quarts for 1995 3.0.
I filled the bottle to its maximum capacity
On a 2000 Ford Ranger : With the engine cold the radiator should be filled to the seat for the radiator cap and the engine coolant reservoir should be filled to the cold mark
1,228 if all boats were filled to capacity.
You don't put water in your radiator, you put antifreeze.
Only the radiator, aprox 4 US qts. Total coolant capacity, 13.4 US qts.
The lifeboats on Titanic were not filled to capacity but they did hold 712 survivors.
The year, make, model and engine info would help, but generally the radiator should be filled to the top and the reservoir should be filled to the "full cold" line. Total capacity is unknown without more info.
The efficiency of an oil-filled radiator is influenced by factors such as the quality of the insulation, the size and design of the heating elements, the thermostat accuracy, and the circulation of the heated oil within the radiator.
