Damn almost a year ago now i had the turbo off the car and i just let the water lines dangle there after i undone them from the turbo, when i put the turbo back on i just bolted the water lines back up and thought nothing of it, now i read stuff about getting air in your coolant system. The car has run fine even though i didnt try to bleed it, i guess i just must have been lucky not to have got air in the system then ..

So anyways with changing the coolant i read the workshop manual and it doesnt say anything about bleeding the air by opening the air valve while the car is running like ive read in a few threads here. So can anyone shead some light on this cos the workshop manual just says top open the air valve while filling up the radiator and to close it if coolant starts coming out of it, and then it says that when its filled up to close tha valve and then start the car etc etc etc .. nothing about opening it while the car is idling.

This is what you should do : ignition on climate control on the highest temp , undo the bleeder fill the radiator until coolant comes from bleeder , do it up and fill the bottle .

Start the engine until normal temp ( thermostat opens ) , let it cool down , then take the radiator cap off and top up , check the bottle and if down fill .

No dramas if you dont open the bleeder , it just means that you will have to put more coolant in after it cools down , the system will bleed itself . It will be fine as long as you top it up , the bleeder is there to make it easier .

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
