Overflow Tank
When installing a new motorcycle radiator, you need to made the radiator overflow tank clean. Otherwise, the mud at the bottom of the bottle will enter the new motorcycle radiator.
By completely flushing and ensuring the cleanliness of the system, the new motorcycle radiator will last longer and run better.
Coolant
Use a glycol-based coolant without silicate in the motorcycle radiator. Because over time, silicate will wear the impeller blades of motorcycles and cause them to fail, usually with catastrophic consequences.
Fill the overflow bottle with coolant to full mark, about halfway through the overflow bottle. From there, it will fill the radiator, so you need to continue filling until both components reach the correct level. The coolant you put into the motorcycle radiator should be a mixture of 50% coolant and 50% water. Do not put undiluted coolant in the radiator.
When removing the old radiator, pour the old coolant into the drain pan. Do not let it drain into the ground, as it may be toxic to animals and pose a danger to the groundwater system. From the drip tray, place it in an airtight container and dispose of it responsibly. Don't try to reuse old coolant in the new radiator.
Air Flush
When installing a new motorcycle radiator, you need to drain the air from the system. For this, air must be discharged from the water pump. Before filling the new radiator, you need to start the engine. Let it run long enough to turn on the thermostat and let the air escape.
If you don't do this, you may end up leaving some hot air in the system. This may cause the engine to overheat, or it may cause engine cavitation, which may cause permanent damage to the engine.
Know your bike
The more you know about bicycles, the easier it is to replace motorcycle radiators. For example, some Honda cars actually have 2 radiators, while other brands and models require you to remove the fairing or even the fuel tank to access the radiator.
