How do you replace a coolant reservoir on a radiator?

Why does Honda Civic have a small coolant valve?
If both seals work correctly the coolant boils at a much higher temperature, in the range of 240 deg F. This allows for MUCH better heat transfer and allows your car to cool off better. The other thing that small valve does is help the system purge air bubbles from within the top of the engine.
Why is the radiator on my Honda Civic overheating?
If the hose goes from cold, to a bit warmer to a bit warmer to a bit warmer than the thermostat isn’t working correctly. For your testing focus on the radiator, not the heater core.

You might see coolant leaking if the tank is cracked or damaged. If your vehicle leaks too much coolant, your engine can overheat. This can lead to head gasket failure or even a cracked engine block.
What causes coolant to leak from the radiator?
The coolant reservoir collects the hot coolant for recycling back into the radiator once it has cooled down. If you are often adding more coolant to the reservoir, you might have a leak. You might see coolant leaking if the tank is cracked or damaged. If your vehicle leaks too much coolant, your engine can overheat.
