Flushing cooling system 2003 Pathfinder

[Micallen]

I used to flush coolant by running engine with radiator drain open, water hose in top of radiator constantly filling. After several minutes of that all the existing coolant is replaced with tap water. Then I would remove hose, let it run another minute or 2, then turn engine off. Then of course I would close radiator drain and fill with coolant/water mix.

 

Is that OK with the path finder? Or would I theoretically need to "Flush" it with distilled water??

That should be fine, you may have to uncap the nipple by the firewall to get any air out of the system though if you flush it. I learned that when I replaced my radiator and filled it up, my truck would then overheat... I uncapped that and revved until coolant came out. All clear
