Hello all,

I have been trying to figure out what exactly Nissan is thinking between the different models in terms of cooling system service. For the G37, the FSM clearly states that there should be an air relief plug on the driver's side heater hose. Some have it, and some don't. I checked the 370z FSM and apparently all 370z models don't have this heater hose bleeder screw. The procedure for both the 370z and g37 is apparently the same - my question for you guys is this:

when you change the coolant in your 370z, how do you bleed all the air out? For the nissan altima, there is a special tool available to ensure all the air has been removed, and keep in mind this is no "spill free funnel."

You can look at some FSM screen shots I have posted in the other thread here:

No air relief plug on heater hose - can't bleed cooling system - MyG37

Any input would be appreciated.
