Why is my coolant reservoir empty after filling?
This is normal. You want to keep air out of the system so you start with a half full reservoir when cold…..as the car heats up and the coolant expands some is sent to the reservoir. When you turn the car off and things cool, it sucks coolant out and back to the radiator.

Why is my car still overheating after adding coolant?
Your car uses a combination of air from the moving car and air blown onto the radiator by the cooling fan. When this air flow is blocked, the coolant isn’t able to properly cool off before being exposed to more heat. If the problem is severe enough, the coolant will boil and the engine will overheat.
What happens if you never change your coolant?
The coolant can become more acidic over time and lose its rust-inhibiting properties, causing corrosion. Corrosion can damage the radiator, water pump, thermostat, radiator cap, hoses and other parts of the cooling system, as well as to the vehicle heater system. And that can cause a car engine to overheat.
Do cars burn off coolant?
The Coolant gets into the engine’s combustion chambers and burns off, which damages the car emission system and catalytic converter. As soon as the head gasket gets blown up, the Coolant enters the combustion chamber causing damage to the engine block or cylinder head resulting in white smoke from the engine.
What happens if you put too much coolant in the overflow tank?
Coolant expands as it heats and contracts when it cools. The extra space prevents damage to your engine and hoses. In worst case scenarios, overfilling your antifreeze tank can lead to electrical damage if overflow comes into contact with engine wiring.
Should the coolant reservoir always be full?
Your coolant reservoir tank should be at least 30% full. A leak means that the stored coolant is dripping out, which will eventually cause a low coolant level. To prevent engine overheat, ensure you check your radiator and coolant level regularly.
