There could be several reasons why the coolant level of your new Pulsar NS 200 reached the minimum limit within 400 kilometers. Here are a few possible explanations:
Coolant leak: One of the most common reasons for coolant loss is a leak in the cooling system. It's possible that there is a small leak somewhere in the system, such as a damaged hose or a faulty radiator, which is causing the coolant to escape.
Manufacturing defect: Although rare, it's possible that there was a manufacturing defect in the cooling system of your specific motorcycle. This could include issues with the coolant reservoir or a faulty seal that is causing the coolant to leak.
Improper coolant fill: If the coolant was not properly filled during the initial setup or maintenance, it could lead to a lower coolant level. This could be a result of human error or oversight during the assembly or servicing process.
Overheating: If the motorcycle's engine is running hotter than normal, it can cause the coolant to evaporate more quickly, leading to a lower coolant level. Overheating can be caused by various factors, such as riding in extreme conditions or a malfunctioning cooling fan.
Incorrect coolant mixture: Using an incorrect coolant mixture or an incompatible coolant for your motorcycle can cause it to lose coolant more rapidly. It's important to ensure that you are using the recommended coolant type and that it is mixed properly according to the manufacturer's guidelines.
If you are experiencing this issue with your new Pulsar NS 200, it's recommended to contact a qualified mechanic or bring the motorcycle to an authorized service center. They will be able to diagnose the exact cause of the coolant loss and take appropriate measures to fix the issue.
