StokieShinobi Posted January 19, 2010 Posted January 19, 2010 Hi all I drained the rad yesterday, I was expecting 8.9 litres to drop out - only 5 came out and 5 went in. I am guessing there is old fluid in the system still. I undid the air release on the water pipe, undid the drain plug on the bottom of the rad, then released rad cap. However it seems not all the fluid came out. Has anyone any tips on getting a complete drain? Quote
rtbiscuit Posted January 19, 2010 Posted January 19, 2010 i'm sure i only purchased 5 litres, can't remember, check the envy wewbiste on the service section, they sell the required amount, and its where i bought mine from and should tell you how much is needed/goes in Quote
StokieShinobi Posted January 19, 2010 Author Posted January 19, 2010 This suggests 8.7? download/file.php?id=4768&mode=view/recommended%20fluids.jpg Quote
StokieShinobi Posted January 19, 2010 Author Posted January 19, 2010 Envy site also confirms this "Due on each P3 service (every 36k miles or 4 years). Coolant capacity 8.7l " Hmmmmmmm, how come I only dropped 5 litres? Quote
ZMANALEX Posted January 19, 2010 Posted January 19, 2010 The rest of the coolant will still be in the engine block, hoses, heater etc. Quote
StokieShinobi Posted January 20, 2010 Author Posted January 20, 2010 I thought this Any tips on how to do a complete drain? I'm gonna do it again but want to get it right so I dont waste more coolant doh! Quote
ZMANALEX Posted January 20, 2010 Posted January 20, 2010 There are removable drain plugs on the side of the block but I tend not to drain completely as bleeding the system afterwards can become problematical. Quote
StokieShinobi Posted January 20, 2010 Author Posted January 20, 2010 I opened the drain plug and filled the rad until fluid came out of the drain plug. I have a feeling not all fluid came out as I did the drain on the ramps, I think I'll give it another go with the entire car raised so that it is level Quote
StokieShinobi Posted January 20, 2010 Author Posted January 20, 2010 Its due a coolant change, and only half the fluid came out Quote
ZMANALEX Posted January 20, 2010 Posted January 20, 2010 Its due a coolant change, and only half the fluid came out And how do you think Nissan do it ? Honestly mate draining the coolant fully is more bother than what it is worth. You could always flush it out with a running hose. Quote
StokieShinobi Posted January 20, 2010 Author Posted January 20, 2010 Maybe I'll leave it then Only thing is when I first start the car I can hear a water splashing noise. I am guessing there is a slight air lock perhaps. All temps run fine Quote
