Honda Rebel 1100 radiator cap may spray hot coolant medium
The radiator cap on some 2021 Honda Rebel 1100 motorcycles was not shaped correctly when it was made, so it may not seal the cooling system tightly. The engine's coolant is under pressure when hot, and a bad seal can let that hot liquid leak out or spray. Honda dealers will put on a new radiator cap and top up any coolant that was lost, at no cost to you.
