**UPDATE** There is a crack at the top of the Radiator.
I removed my strut bar today as i needed to replace my spark plugs. Did the removal and had to dip out. Before i removed it i noticed some coolant had leaked but i couldnt see from where, yet my reservoir still had coolant in it. I took a quick trip to the shop and the car has started overheating bad (no steam or smoke but ran into the hot). I had to stop times in a 5 min trip to let it cool. Does this look like a water pump issue? The fans kick but no difference in temp control from the a/c both cold and hot are the same temp (blowing cold air). both top and bottom hose pipes are hot while running and can be squeezed? If it is a leak, could i just throw some StopLeak in there till I can get the radiator fixed?
Edit: The coolant has come through the top of the Radiator and after I drained it there was less than a litre that came out. Bit the bullet and bought a Mishimoto Radiator. Just to be safe a new water pump and Mishi thermostat.
Parts Purchased;
- Mishimoto Performance Alluminum Radiator
(MMRAD-350Z-07)
- Mishimoto Racing Thermostat
(MMTS-350Z-07)
- Genuine OEM Nissan Water Pump (JustJap)
(BK1010-JK20A)

glad you got it figured out. the water pump is completely unrelated if you want to save $ on the labor.

Yeah I know but it seems to be getting harder and harder to find parts in Australia for it. Especially for the HR so I thought I might aswel grab one now while i can just incase something else goes wrong down the line haha.
