I bet after seeing the topic you were prob like “not again” ha.

this topic is slight different though, no worries.

Here’s the story, I bought my 04 G35 -105k Miles from a young DR. In NY, he didn’t drive it much, especially after it overheated and the radiator neck exploded... he took it to the shop and they said the water pump was bad and it will need a head gasket repair.

I still bought it anyway;
I installed a new radiator, new thermostat, drained the system, refilled and then burped...I was able to drive the car for about 18 Miles before it started overheating again.. I tried to burp the system once more.. and that still didn’t help.. so i was thinking it really might need a water pump and or head gasket job...

Long story short, I was so furious at myself at this point.. while I was burping for a third time.. I noticed that the right fan (facing the car) hasn’t came on at all ( over 5 mins) to my surprised, the fan motor was shot... I ordered a replacement motor, replaced the old one and my car hasn’t overheated since ... I hope this helps someone.
