The myth that “thick coolant is good coolant” is a common misconception among some customers. The idea behind this myth is that a thicker coolant might seem like it would provide better protection and cooling, but in reality, it can actually cause more harm than good.
Here’s why the myth is misleading:
The main function of engine coolant is to absorb and dissipate the heat, avoid freezing and provide protection against corrosion.
Flow Issues: Coolant that is too thick can have difficulty circulating through the narrow passage engine and heat exchanger /radiator core. The engine’s cooling system relies on a coolant that flows smoothly and efficiently to absorb and dissipate heat. A thick coolant can slow down the flow, reducing its ability to cool the engine effectively.
Strain on the Pump: The water pump in the cooling system is designed to circulate coolant at a certain viscosity. A thicker coolant can put unnecessary strain on the pump, leading to premature wear and even pump failure over time.
Reduced Heat Transfer: Coolant is designed to maintain a balance between heat transfer and flow. If the coolant is too thick, it may not be able to absorb and transfer heat as efficiently as it should, potentially leading to engine overheating which increases strain on engine causing engine to run hotter than usually hampering lubrication, fuel efficiency and overall engine durability.
Risk of Deposits: Thicker coolants are more prone to creating scaling or deposits in the system in longer run due heat induced agglomeration, which can clog the radiator, hoses, and other components, making the cooling system less effective.
Obstruct Corrosion Prevention: Thicker coolant containing rust preventive and descaling additives will not able fully utilises the potential of additive components due to compatibility. In longer period of time or in continuous usages thicker coolant can cause localised rust spots due ineffective wetting also thicker coolant give raise to the electrical conductivity due to internal friction causing localised rust spots to appear in the system.
Cavitation: Thick coolants can lead to severe cavitation issues that could create air pockets and foaming in the system. This will increase heat spot and excessive pressure on rubber hose and water pump.
Seal and Hose: Thicker coolant may cause compatibility issues with EPDM and Nitrile seals and hoses causing them to swell which could lead to leakage.
Manufacturer Specifications: Car manufacturers carefully design their cooling systems and specify the appropriate coolant formula, including the right viscosity. Using a coolant that’s too thick goes against these specifications and can void warranties or cause long-term damage.
So, the best coolant is not necessarily the thickest one but the one that meets the manufacturer’s recommended specifications for both viscosity and antifreeze concentration. Using the correct coolant will ensure optimal performance and protect the engine from overheating and corrosion.
