I recently flushed and refilled the cooling system. I am worried about air pockets in the cooling system and was wondering where the air relief valve on our cars are. This is for the 5th gen 3.0 VQ. I have a Haynes manual only the picture they show of the location of the air relief valve is for the 3rd gen maximas. Any of you that have the ESM or just know the exact location please post. Thanks for your time.
