Coolant change... Dont need over 9 litres!

[letsgotopless]

I recently did a differential and gearbox oil change, no problem .

The coolant swap came next and followed several youtube guides to make sure i was not missing something even though its a simple and straight forward operation.

I warmed the car up, put heater setting on hot, ramped the front up a little and then released the fluid by removing the plastic plug under the radiator and opened the pressure cap. After 20 mins i opened the bleed valve on the small top hose and left it all for half hour to fully drain. I thought about turning over the engine briefly to get the water pump to send some more out but decided against that and anyway, no one had suggested it.  I opened my first 5 litre bottle of nissan premixed coolant and slowly filled up and continued the process over a few hours according to the guides. All easy but after fully filling and bleeding the system with no air left therein I found that no more than the 5 litres was needed.

Have any of you guys found this also. Now I have a spare unopened 5 litre of coolant.

if you completely drain the block and the heater matrix as well as the radiator etc. you will require 10 litres.

Hello all. When talking of "Coolant Change" as the service schedule is it a complete drain or radiator only ?

Mine needs doing and want to get it right but work smarter not harder.

Thanks.

Radiator only. I questioned this before too.

 

If you drain the block, you'll have a lot more difficulty bleeding the whole system.

Thanks; appreciate it.
