-- To replace, remove the O-ring -2- from the connector coupling -4- with a suitable tool (do not use a sharp tool). While doing this, make sure the connector coupling and the O-ring seat are not damaged.

-- Coat the new O-ring or Y-ring with coolant and insert it in the coolant hose.

-- Press the coolant hose onto the connection -1- until it engages audibly.

-- Press the coolant hose on again and pull to make sure the connector coupling is engaged correctly.
