Found the expansion tank empty after a short run on sunday. Topped up radiator and expansion tank and got the car up to temp and found that the rubber hose under the distributor is leaking. Not sure if this is the cool or hot side of the turbo coolant feed but i believe i need a 3mm hose as the pipe measures this at the turbo end of the pipe. Can anyone confirm this? Is this a part i need to get from nissan or can i make my own up using a suitable rubber hose?
