4 Causes Of Engine Losing Coolant But No Leakage

4 Causes Of Engine Losing Coolant But No Leakage – Coolant, also known as radiator fluid and antifreeze. Coolant is very important for the vehicle cooling system. A mechanical failure in a vehicle’s cooling system is one of the main causes of a car breaking down while traveling. Paying attention to the amount of coolant through the height and condition is part of the routine maintenance of the vehicle that we must do as ICE engine owners.

4 Causes Of Engine Losing Coolant But No Leakage

In general, there should be a leak if the vehicle loses a large amount of antifreeze both in the reserve tank and especially on the radiator. However, the car can lose coolant but no visible leakage at all in the cooling system. What should you do when the coolant disappears from the reservoir, especially from the radiator without leaving a trace?

It may sound weird and magical when you think of losing your cooler in that way. But, everything is not as complicated as it seems. A poorly maintained antifreeze system, damaged components, or rapid changes in driving style can cause this coolant loss.

4 Causes Of Engine Losing Coolant But No Leakage

Here are the main possible causes of coolant missing from your car’s cooling system but not appearing to leak at all.

First – Overflown Cooling System

Overfilling the cooling system can be the reason for the mysterious loss of coolant. You must keep the radiator fluid at the required level only. There is a MAX / MIN label on the tank which indicates the ideal antifreeze level when the engine is cold. The coolant in the radiator must be just below the neck of the filler.

If it is overfilled, what will happen is that water will spill out of the reservoir tank and make it appear as if you have lost coolant.

Second – An Inner Puncture

When you lose coolant but there are no visible leaks in the cooling system, some parts could be the culprit in this case. It could be a broken head gasket, a cracked cylinder head, a damaged cylinder bore, or a manifold leak.

If the antifreeze disappears for no apparent reason, inspect this component for cracks, damage, or defects. Luckily, if the coolant is not mechanical, you will find it mixed with oil. This indicates that the liquid did not pass to the engine but only that it was evaporating through something else.

Third – Broken Radiator Cover

The radiator cap can be damaged over a period of time. This can cause antifreeze to enter while you are driving. A damaged cap will allow coolant to easily escape from the radiator before the minimum engine pressure is reached. This amount of water will then evaporate or spill from the reserve tank. As a result, the coolant will decrease as if without a problem and there is no sign of leakage from the cooling system.

Fourth – Engine Overheats

There is a very close relationship between engine overheating and cooling. Loss of fluids can cause overheating. However, on the contrary, overheating can also cause loss of refrigerant.

Refill the tank coolant to the maximum limit and pay attention to the condition of the engine and the rate at which the coolant is used. Then pay attention to the engine temperature. When the engine temperature reaches a hot level and is accompanied by reduced cooling, it is clear that the engine is overheating, causing engine coolant loss.

If this case occurs then you must immediately take your car to a service point for further handling.
