Description Reviews MINI Cooper Coolant Line Banjo Bolts. These are the banjo bolt that holds the turbo coolant line to the front of the turbo. These fit both N14 & N18 MINIs in both coolant line locations. You can normally reuse these bolts if you actually have to take them off; but some people want to replace everything. They require new crush washers to make it work correctly; so we include them in this kit. Brand new MINI OEM Bolts. You can replace these when adding a new coolant line for your N14 or N18.
