I have a 2009 370z mt. I am 90% sure the water pump failed.
Currently having a leaking issue that only occurs when the car is running, and worsens as the RPM and coolant temperature increases. The leak is located near the right of the AC compressor, which leads me to believe coolant is leaking from the weep hole due to some failure of the water pump. I don't see any leaks coming from the metal cooling hose connected near the headers, either. Other things of note: when the weep hole is leaking a lot, I can hear a faint constant whirring sound which I feel is indicative of a mechanical failure of the pump, likely due to the propeller. bearing failing. Only check engine light I have is for high coolant temperatures. Don't think its a head gasket issue cause: No steaming from the heads nor any coolant dropping on the headers Oil and coolant dont seem to be mixing. No gases from combustion coming out of radiator cap when revving. At the very least, since I have an 09 this gives the excuse to replace the gallery gaskets while I am at it. |
