How to check the coolant level in a GSX250?
1 Answers
Open the radiator cap or expansion tank cap, start the engine. If there is no coolant in the radiator at all, you can first add some water, then start the engine and slowly add more water. Continue until water overflows, then tighten the cap securely. You can also gently rev the engine to raise the coolant temperature. Be sure to bleed air from the system when adding coolant.
