Motorcycle engine coolants are the dedicated liquid compound that is used in the engine cooling system and it helps to reduce or regulate the engine temperature. Thus engine coolants work to keep the engine temperature at the correct operating temperature level and allow the engine to perform even in extreme riding and weather situations. Coolants are generally water-based fluids where various additives are added to give them certain properties usually the compound is colored green, blue, or even pink.

You know high-performance motorcycles or any other internal combustion engines produce a lot of heat due to combustion in a higher compression ratio. Hence the engine must be cooled to a proper temperature level while it running to avoid damage. So here the cooling system does its job and liquid cooling is the best solution to keep the temperature level regulated even in extreme riding or weather conditions. 

In the liquid-cooling system, the engine coolant runs through certain cooling channels or passages in the engine block and heads and collects the heat from surrounding metal surfaces. Therefore, the coolant then goes to the cooling radiator and disposes of the access heat through the radiator. Thus it picks up the heat and disposes of it through the radiator. Hence a perfect coolant has to be properties with certain characteristics like high thermal capacity, low viscosity, non-toxic, non-corrosive, chemically inactive to the metal, and anti-freezing in sub-zero temperature.

Accordingly, there are various types and characteristics of engine coolant available in the world markets which are formulated for different types of motorcycles which also composed to work in different weather conditions. So it’s necessary to use the manufacturer's recommended type or category of coolant for a certain model of motorcycle. Further, just like the engine lubricants the coolant also has its expiry and it needs to be inspected regularly to be sure the system has enough liquids. And again after a period the coolant also needs to be replaced perhaps it’s not frequent like the lubricating oils.

FAQ – Frequently Asked Questions

1. What is motorcycle engine coolant?

Ans: A motorcycle engine coolant is a kind of water-based liquid compound that is used to reduce or regulate the engine temperature of a motorcycle alike the other internal combustion motor engine coolants. The engine coolants are most commonly a chemical composition that is based on water and properties with high thermal capacity, anti-freezing characteristics, low viscosity, non-toxic, chemically inactive, and neither cause nor promote corrosion of the cooling system. 

2. What does a motor engine coolant does for an engine?

Ans: The motor engine coolants mainly reduce or regulate the temperature of internal combustion motor engines. The engine coolants work to keep the engine temperature at the correct operating temperature level and allow the engine to perform even in extreme riding and weather situations.

3. What are the common types of motor engine coolants?

Ans: There are various types and characteristics of engine coolant available in the world markets which are formulated for different types of motorcycles which also composed to work in different weather conditions. So it’s necessary to use the manufacturer's recommended type or category of coolant for a certain model of motorcycle.

4. Do the motor engine coolants need replacements?

Ans: Just like the engine lubricants the engine coolant also has its expiry and it needs to be inspected regularly to be sure the system has enough liquids. Hence, after a period the coolant also needs to be replaced as it loses its cooling properties perhaps it’s not so frequent as the lubricating oils.

5. Name the popular engine coolant brands available for motorcycles in Bangladesh

Ans: MOTUL, Liqui MOLY, Shell, Mannol, Castrol, Motorex, Omera, Bizol, ACL, Apsco, etc. are the popular engine coolant brands available for motorcycles in Bangladesh.

6. Does Bangladesh manufacture any of the engine coolants for motorcycles?

Ans: Bangladesh doesn’t produce any of the brands of motor engine coolants but a few brands of engine coolants are packed here for commercial distribution in the domestic market.
