Engine coolant is mixed with water, usually in a 50/50 ratio, and poured into the appropriate reservoir for your engine. The chemical ethylene glycol is used as a base to create a fluid that is pumped through the car’s engine to regulate and maintain optimum operating temperature during extreme hot or cold weather conditions.
As the outside temperature changes from hot to cold, coolant is pumped throughout the engine block to maintain a consistent operating temperature.
Maintaining proper coolant levels is very important. and that your car loses fluid is worrying, but it is even more so when you lose antifreeze without there being a leak.
Where does the coolant go if the car doesn’t have any leaks?
A poorly maintained antifreeze system, faulty components, or a quick change in driving style can all contribute to this coolant disappearing.
Here are some of the reasons why you might be losing coolant.
1.-Too much refrigerant in the system
Overfilling the system may be the reason for the mysterious disappearance. You have to keep the liquid at the required level. There is a label on the tank that indicates the ideal level of antifreeze when the engine is cold. The coolant in the radiator should be just below the filler neck.
2.- An internal puncture
When coolant is leaking but no leak is visible, multiple parts may be to blame. It could be a blown head gasket, cracked cylinder head, bad cylinders, or a manifold leak. It could also be a hydraulic lock.
If the coolant disappears for no apparent reason, check these components for cracks, damage, or defects. Either of these problems can destroy the engine if it goes on too long.
3.- Worn radiator cap
The radiator cap can deteriorate over time, allowing antifreeze to leak out while you drive. A clogged radiator system could also be a problem as it blocks the flow of the fluid. Check the radiator when the coolant disappears without a trace
4.- Engine overheated
Engine and coolant overheating are closely related to each other. Fluid loss can lead to the overheat condition, but overheating can also contribute to coolant loss. Simply fill the tank to the maximum limit and keep an eye on the engine health and coolant usage rate.
