How do I get rid of an airlock in the coolant system of a Derbi GPR 125 2009
Use a airlift or comparable coolant system air removal/refill system.You attach the unit to the coolant system filler and it vacuums all air from the system,then you use the supplied hose to return the coolant into the vacuumed system.This fills the system with just coolant and no air.
