glrnet Posted December 23, 2011 Share Posted December 23, 2011 It very much depends on the level of protection you want, check what the anti freeze manufacturer recommends, you should find details on the container. Quote Link to comment Share on other sites More sharing options...
Dblock Posted December 23, 2011 Share Posted December 23, 2011 I think its 10 or 11 litres for a full flush. I would need to check though. Quote Link to comment Share on other sites More sharing options...

Also OP might be buying it ready mixed. Quote Link to comment Share on other sites More sharing options...
se350z Posted December 24, 2011 Author Share Posted December 24, 2011 It very much depends on the level of protection you want, check what the anti freeze manufacturer recommends, you should find details on the container. ^ i just checked it and it says mix/propotion --- protection 1. bottle (antifreeze) + bottle (water) + bottle (water) --- -20^C 2. bottle (antifreeze) + bottle (water) --- - 36^C I guess option number one should be ok, because i believe we wont see -20^C however how many litres of water do i need to put?, for example if its 9 litres, i will be putting 6 litres of water and 3 litres of anti freeze with summer coolant.

HassanZ Posted December 24, 2011 Share Posted December 24, 2011 The full capacity is 8.7 litres. I purchased 'premix' coolant from Nissan so there was no stress about diluting the coolant with distilled water... Quote Link to comment Share on other sites More sharing options...
ZMANALEX Posted December 24, 2011 Share Posted December 24, 2011 If you are flushing the system then you will require 2 x 5 lts of Nissan Pre Mix. Otherwise a you will be safe at a 50/50 mix. Alex. Quote Link to comment Share on other sites More sharing options...

stubzie83 Posted December 24, 2011 Share Posted December 24, 2011 I changed the water, but it gives cold air from heater any ideas what i done wrong? air lock +1 When I did mine it was an absolute pain to get the air out of the heater matrix. I found the best method was to raise the front of the car up so that the radiator cap was above the air bleed valve. You can then force coolant into the heater matrix and the air eventually comes out of the radiator. It takes a while, a lot of massaging coolant hoses and a lot of cursing to get done.

Dynamic Turtle Posted February 9, 2012 Share Posted February 9, 2012 Thread gravedigging.... Is anti freeze used to prevent cracks from happening within the engine due to expanding ice water? Or is it because you guys are acutally crazy enough to use a 350z when it's -20c outside? Sorry, auto noob question I know. Quote Link to comment Share on other sites More sharing options...
