My toyota sienna overheats at all time even if it is raining especially if you want to speed up or climb hill the temperature will go up. Immediately I start the car water will start coming from engine to fill the coolant reservoir.

Do you need to keep topping up the radiator frequently?
Has the engine overheated badly previously?
If the system has a radiator cap on the radiator, replace it and retest.
Are the cooling fans working?

The problem should be due to loss of coolant. Check for leaks.
